اعلام وابستگیها
برای افزودن وابستگی به Benchmark، باید مخزن Google Maven را به پروژه خود اضافه کنید. برای اطلاعات بیشتر، مخزن Maven گوگل را مطالعه کنید.
ماکروبنچمارک
برای استفاده از Macrobenchmark در پروژه خود، وابستگیهای زیر را به فایل build.gradle مربوط به ماژول macrobenchmark خود اضافه کنید:
شیار
dependencies { androidTestImplementation "androidx.benchmark:benchmark-macro-junit4:1.4.1" }
کاتلین
dependencies { androidTestImplementation("androidx.benchmark:benchmark-macro-junit4:1.4.1") }
Microbenchmark
برای استفاده از Microbenchmark در پروژه خود، وابستگیهای زیر را به فایل build.gradle ماژول microbenchmark خود اضافه کنید:
Groovy
dependencies { androidTestImplementation "androidx.benchmark:benchmark-junit4:1.4.1" } android { ... defaultConfig { ... testInstrumentationRunner "androidx.benchmark.junit4.AndroidBenchmarkRunner" } }
Kotlin
dependencies { androidTestImplementation("androidx.benchmark:benchmark-junit4:1.4.1") } android { ... defaultConfig { ... testInstrumentationRunner = "androidx.benchmark.junit4.AndroidBenchmarkRunner" } }
The Microbenchmark library also provides a Gradle plugin to use with your microbenchmark module.
This plugin sets build configuration defaults for the module, sets up
benchmark output copy to the host,
and provides the
./gradlew lockClocks task.
To use the plugin, include the following line in the `plugins` block in your top-level
build.gradle file:
Groovy
plugins { id 'androidx.benchmark' version '1.4.1' apply false }
Kotlin
plugins { id("androidx.benchmark") version "1.4.1" apply false }
Then apply the plugin to your benchmark module's build.gradle file
Groovy
plugins { id 'androidx.benchmark' }
Kotlin
plugins { id("androidx.benchmark") }

تغییرات API
- ضبط ردیابی Perfetto ساده شده روی دستگاه. ( I48810 )
- APIهای آزمایشی افزونه
TraceProcessor.runServerرا ازandroidx.benchmark:benchmark-macroبهandroidx.benchmark:benchmark-commonو به بستهandroidx.benchmarkمنتقل کنید. این کار امکان استفاده از آنها را در microbenchmarkها در آینده فراهم میکند. ( Ie25bb , b/393640753 )
رفع اشکالات
- پیادهسازی پردازنده ردیابی (و همچنین ضبط ردیابی Perfetto بدون نیاز به پیکربندی) را برای استفاده از Perfetto نسخه 56.0 ( I8fb9d ) بهروزرسانی کنید.
-
androidx.benchmark.requireAotوandroidx.benchmark.requireAotرا به طور پیشفرض روی true تنظیم کنید. این پیشفرضهای ایمنتر تضمین میکنند که کامپایل قبل از اجرای microbenchmarks انجام شود (به طور پیشفرض با افزونه gradle هنگام استفاده از AGP 8.4+ فعال است)، وmeasureRepeatedدر نخ اصلی استفاده نمیشود، جایی که میتواند باعث ANR شود. ( I1bc3c , b/379115078 ) - افزایش زمان توقف اجرای Perfetto از ۵ به ۳۰ ثانیه (فقط برای جلسات Perfetto که در بنچمارک گرفته شدهاند). اضافه شدن گزارش خطای واضحتر هنگام بروز مشکل. ( If188f ، b/435589290 )

androidx.benchmark:benchmark-*:1.5.0-alpha02 منتشر شد. نسخه 1.5.0-alpha02 شامل این کامیتها است.
رفع اشکالات
Add partial support for baseline profile generation for Kotlin multi-platform modules. Typically dependencies on profiles can be defined using the
baselineProfileGradle configuration in the dependencies block, but this doesn't currently work for KMP modules.kotlin { androidLibrary { namespace = "com.example.namespace" compileSdk = 36 } sourceSets { androidMain.dependencies { // THIS DOES NOT WORK // baselineProfile(":yourProducerProject") } } }در عوض، شما باید وابستگیهای خود را با استفاده از افزونه
baselineProfile** تعریف کنید. ( Ie19c4 )plugins { id("org.jetbrains.kotlin.multiplatform") id("com.android.kotlin.multiplatform.library") id("androidx.baselineprofile.consumer") } kotlin { androidLibrary { namespace = "com.example.namespace" compileSdk = 36 } sourceSets { androidMain.dependencies { // ... } } } // Define dependencies // This works ! baselineProfile { variants { androidMain { from(project(":yourProducerProject")) } } }
نسخه ۱.۵.۰-آلفا۰۱

androidx.benchmark:benchmark-*:1.5.0-alpha01 منتشر شد. نسخه 1.5.0-alpha01 شامل این کامیتها است.
- Macrobenchmark 1.5 از
UiAutomator2.4 برای سادهسازی تعامل با برنامهی اندازهگیریشده استفاده میکند. شیء MacrobenchmarkScope اکنون از UiAutomatorTestScope ارثبری میکند که به شما امکان میدهد از APIهای مدرنUiAutomatorمانندonElement { ... }.click()استفاده کنید. - برای اطلاعات بیشتر در مورد
UiAutomator2.4، به مستندات مراجعه کنید.
ویژگیهای جدید
- افزونه Gradle پروفایل پایه دیگر در AGP 9.0
newDsl=falseنیاز ندارد ( Iaaac7 ، b/443311090 ) - پیکربندی ردیابی را گسترش دهید تا اندازه هسته (مثلاً کوچک/بزرگ) را در ردیابیهای سیستم/کامل ثبتشده توسط معیار لحاظ کند. ( I8e397 ، b/457469959 )
تغییرات API
- (در رابط کاربری)
startActivitywait برای منتظر ماندن برای پنجره جدید تغییر کرد. ( I35da6 ، b/440021797 ) - Stabilize
BlackHoleAPIs in androidx.benchmark. ( I2b67e , b/451749438 ) - Add
@JvmOverloadsfor convenience constructors forPerfettoTraceRule. ( I1510a , b/443763207 )
نسخه ۱.۴
نسخه ۱.۴.۱
۱۰ سپتامبر ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.1 منتشر شد. نسخه ۱.۴.۱ شامل این کامیتها است.
رفع اشکالات
- Fixed
perfettoSdkTracing=true(eg when tracing Compose in a microbenchmark) would kill the target process if it was already running, and a StartupMode wasn't specified. ( Ib2c1f )
نسخه ۱.۴.۰
۳۰ ژوئیه ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0 منتشر شد. نسخه ۱.۴.۰ شامل این کامیتها است.
تغییرات مهم از زمان ۱.۳.۰
میکروبنچمارک
- وظایف Gradle
lockClocksوunlockClocksبه جای قرار گرفتن در سطح بالا برای رعایت ایزولهسازی پروژه Gradle، به پروژههای بنچمارک منتقل شدند. - Refactored
BenchmarkRuleto be built on top of coroutines, and support betteryield()behavior. This should significantly reduce the risk of ANRs during benchmark runs, especially long CI runs. Note: UI Benchmarks should run withmeasureRepeatedOnMainThread
Macrobenchmark
- Added workaround on API 34+ for
CompilationMode.None()would have inconsistent performance due to ART's verify now partly compiling apps after first launch. - ویژگی آزمایشی - Startup Insights میتواند با ارسال
MacrobenchmarkRule(..., experimentalConfig = ExperimentalConfig(StartupInsightsConfig(isEnabled = true)))مشکلات رایج خاصی را در یک Macrobenchmark هنگام راهاندازی برجسته کند. - ArtMetric اضافه شده است که میتواند برای تشخیص کامپایل JIT و بارگذاری کلاسهای بهینهسازی نشده استفاده شود - هر دو برای اعتبارسنجی بهینهسازیهای Baseline Profile مفید هستند.
Baseline Profiles
-
BaselineProfileRuleاکنون پروفایلهای برنامههای چندپردازشی را جمعآوری میکند.
سایر تغییرات
- TraceProcessor به کتابخانهی خودش (
androidx.benchmark:benchmark-traceprocessor) منتقل شده است تا در موارد دیگر، بتوان از آن خارج از معیارهایMacrobenchmarkاستفاده کرد. همچنین میتوان آن را با تعریف ServerLifecycleManager خودتان، روی Desktop JVM اجرا کرد.
نسخه ۱.۴.۰-rc01
۱۸ ژوئن ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0-rc01 منتشر شد. نسخه 1.4.0-rc01 شامل این کامیتها است.
رفع اشکالات
- Added workaround for runtime images causing
CompilationMode.None()to not measure worst case performance after first iteration. Unfortunately this workaround requires a delay of 5 seconds to intentionally corrupt the runtime image at the beginning of each macrobenchmark suite ( I4a4f1 ).
Version 1.4.0-beta02
۴ ژوئن ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0-beta02 is released. Version 1.4.0-beta02 contains these commits .

رفع اشکالات
- قالب لینک بینش راهاندازی
TraceProcessorبهروزرسانی شد تا از افزونه صحیح استفاده کند و جداکننده واضحتری داشته باشد (:کوتاهتر از%3Aاست و هر دو پشتیبانی میشوند) ( Ie18ef ) - Always use force-stop to kill processes, even when rooted and killing system apps. Fixes exceptions of the form:
Expected no stdout/stderr from killall ... No such process. ( Idca2c )
مشارکت خارجی
- کنترلکنندهی استثنای پروکسی برای
TraceProcessorHttpServer( I480f5 ) اضافه شد.
نسخه ۱.۴.۰-آلفا۱۱
۹ آوریل ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0-alpha11 is released. Version 1.4.0-alpha11 contains these commits .
تغییرات API
- آرگومان timeout مربوط به
TraceProcessorتغییر کرد: مدت زمان برای timeoutMs long جهت قابلیت استفاده از فراخوانیکننده جاوا. ( I9fbb5 ) - Mark
TraceProcessorconstructor as internal. Callers should useTraceProcessor.startServerorTraceProcessor.runServer. ( Ia8c5b )
رفع اشکالات
- هنگام kill کردن برنامه با
MacrobenchmarkScope.killProcess، نتایج دستور kill را اعتبارسنجی کنید تا از خطای بیصدا و خطای timeout جلوگیری شود. ( I84555 )
بهروزرسانیهای وابستگی
- این کتابخانه اکنون سطح زبان Kotlin 2.0 را هدف قرار میدهد و به KGP 2.0.0 یا جدیدتر نیاز دارد. ( Idb6b5 )
نسخه ۱.۴.۰-آلفا۱۰
۲۶ مارس ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0-alpha10 is released. Version 1.4.0-alpha10 contains these commits .
تغییرات API
- Increased default timeout for
TraceProcessorserver load and querying to 120 seconds (from 60/30 previously), and made both configurable with one timeout parameter. ( Ifec87 )
رفع اشکالات
- چند مشکلی که هنگام بنچمارک یا گرفتن پروفایل یک برنامه بدون
profileinstallerرخ میداد، برطرف شد وBroadcastRecieverنیز در آن گنجانده شده است. این مشکل فقط روی دستگاههای روت شده تأثیر میگذارد. ( Ied308 )
نسخه ۱.۴.۰-آلفا۰۹
۱۲ مارس ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0-alpha09 is released. Version 1.4.0-alpha09 contains these commits .
تغییرات API
-
TraceProcessorو Session API با Handleهای قابل بستن، برای استفاده آسانتر با چرخههای عمر سفارشی اضافه شدند. این همچنین گامی در جهت فعالسازی آسانتر استفاده از Coroutine و Java API است. توابع افزونهTraceProcessor.runServer {}اکنون به صورت آزمایشی علامتگذاری شدهاند، زیرا احتمالاً در آینده منتقل میشوند و غیرآزمایشی میشوند. ( I358b4 )
رفع اشکالات
- رفع مشکل عدم کارکرد ضبط Benchmark و Baseline Profile با API 36 به دلیل تغییر در
pgreptoybox که اکنون برای چاپ خط فرمان کامل-aنیاز دارد. ( Idc991 ) - پیکربندی ردیابی پیشفرض را فیلتر کنید تا خطر از دست رفتن دادهها در ردیابیها در سطوح API جدیدتر کاهش یابد. ( I54e8a )
- Added experimental
androidx.benchmark.killExistingPerfettoRecordingsinstrumentation argument, which can be set tofalseto allow pre existing perfetto trace capture to continue. By default pre existing perfetto trace captures on device are killed to prevent interference. ( I02a3c ) - فیلد JSON مربوط به
context.osCodenameAbbreviatedاکنون برای نسخههای سیستم عامل منتشر شده در API 35 و بالاتر،RELخواهد بود، زیرا نامهای کد غیر عددی دیگر توسط پلتفرم اصلی پشتیبانی نمیشوند. ( Ib17fd ) - Fixes crash in
FrameTimingMetricwhen resynced frames occur. ( I7c6f4 , b/394610806 ) - No longer assume
Choreographer#doFrameis the top of the stack frame on the main thread forFrameTimingQuery. ( Iee0e0 , b/340206285 )
نسخه ۱.۴.۰-آلفا۰۸
۱۲ فوریه ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0-alpha08 is released. Version 1.4.0-alpha08 contains these commits .
تغییرات API
- APIهای افزونهی
TraceProcessor.runSession()به حالت آزمایشی منتقل شدند، زیرا احتمالاً در نهایت در اندروید به سازندههای عینی تبدیل خواهند شد. ( Ib0528 , b/393640753 ) - Most of the implementation of Startup Insights are now public/experimental, and move to the
TraceProcessorartifact SeeStartupInsights. ( I0aa00 ) -
BenchmarkRule.runWithTimingDisabled {}به نفعBenchmarkRule.runWithMeasurementDisabled {}منسوخ کنید، که رفتار را واضحتر توصیف میکند - همه معیارها متوقف میشوند. علاوه بر این، سوپرکلاسMicrobenchmarkScopeرا در معرض دید قرار دهید زیرا تعریف مجدد تابعrunWithMeasurementDisabledبرای دسترسی آزاد امکانپذیر نیست، زیرا درونخطی است. ( I9e23b ، b/389149423 ، b/149979716 ) - Benchmark libraries have moved to Kotlin 2.0. ( I9d1e0 )
- Removed
androidx.benchmark.startupProfiles.enableinstrumentation argument. It is no longer useful, as it can be controlled byincludeInStartupProfilearg inBaselineProfileRule.collect(). ( I39eb4 )
رفع اشکالات
- تعداد توابع داخلی Microbenchmark که در طول پروفایلینگ فراخوانی میشوند، کاهش یافته است تا مثلاً ردیابی متدها واضحتر شود ( Ifaed8 )
- Speculative fix for crashes: 'Failed to stop [
ProcessPid(processName=perfetto, pid=...)]'. Now Benchmark will log a message instead of crashing when a background Perfetto process isn't able to be stopped before running the benchmark. ( I37d3e , b/323601788 ) - رفع
IllegalStateExceptionsبا برچسب 'Expectedpm dump-profilesstdout' که ناشی از بررسی بیش از حد دقیق فرمت خروجی بود. ( I358dc )
نسخه ۱.۴.۰-آلفا۰۷
۲۹ ژانویه ۲۰۲۵
androidx.benchmark:benchmark-*:1.4.0-alpha07 منتشر شد. نسخه 1.4.0-alpha07 شامل این کامیتها است.
ویژگیهای جدید
-
BaselineProfileRuleاکنون یک رابط برنامهنویسی کاربردی (API) به نامcollectWithResults(...)معرفی میکند که شامل فهرستی از مسیرها به پروفایلهای محاسبهشده است. ( I056f8 ) - آرگومان ابزار
androidx.benchmark.measureRepeatedOnMainThread.throwOnDeadlineاضافه شد که میتوان آن را روی false تنظیم کرد تا رفتار throw on deadline مربوط بهmeasureRepeatedOnMainThreadبرای تست محلی غیرفعال شود. در غیر این صورت توصیه نمیشود، زیرا احتمال ANRها را در طول تستها افزایش میدهد. ( Idbeec , b/353226476 )
تغییرات API
-
@JvmOverloadsبه سازندهMicrobenchmarkConfigاضافه شد. ( I13fd3 ) - Refactored
BenchmarkRuleto be built on top of coroutines, and support betteryield()behavior. This refactor removed several experimentalBenchmarkStateAPIs, but will be followed by replacements as needed. Additionally, addedrunWithMeasurementDisabledto clarify behavior (all measurement is paused). In the future,runWithTimingDisabledwill be deprecated. ( I19837 , b/389149423 , b/311242861 ) - Move
PerfettoTraceProcessortoTraceProcessorin a newandroidx.benchmark:benchmark-traceprocessorartifact, and make most of its API non-experimental. Any customTraceMetricor anything reading from traces will need to update to the newTraceProcessorimport. The newTraceProcessorAPI works exactly like the old one, but is a standalone interface library (somewhat analogous to theandroidx.sqlitelayer from Room) with an Android-specific implementation built into macrobenchmark. The new artifact can be used on JVM as well, but currently you'll need to start your own copy of theTraceProcessorbinary and offer a port to connect to it on. ( I3a767 , I62563 , b/381134564 )
رفع اشکالات
- Throw a clearer error message when
MacrobenchmarkScope.startActivityAndWaitfails to launch the target process (potentially due to a crash in the target process), instead of the more ambiguous 'Unable to confirm activity launch completion' message ( I3539b ) - Fixed several syntax errors in Kotlin samples, and syntax highlighting in several Java / build.gradle samples. ( Ib3808 )
- مستندات پارامترهای
ArtMetricوCaptureInfoشفافسازی شده ( I96e60 )
نسخه ۱.۴.۰-alpha06
۱۱ دسامبر ۲۰۲۴
androidx.benchmark:benchmark-*:1.4.0-alpha06 is released. Version 1.4.0-alpha06 contains these commits .
تغییرات API
- استفاده از
@Language("sql") درPerfettoTraceProcessor.Session.query() حذف شد، زیرا برجستهسازی/تجزیه Studio با مشکل مواجه است. ( Idc2fa ، b/377733398 )
رفع اشکالات
- این کتابخانه اکنون از حاشیهنویسیهای nullness از نوع JSpecify استفاده میکند که از نوع استفاده میکنند. توسعهدهندگان کاتلین باید از آرگومان کامپایلر زیر برای اعمال استفاده صحیح استفاده کنند:
-Xjspecify-annotations=strict(این پیشفرض است که از نسخه ۲.۱.۰ کامپایلر کاتلین شروع میشود). ( I46810 ، b/326456246 ) -
ArtMetricاصلاح شد تا بار کلاس (نه init) را گزارش دهد، و مستندات بهبود یافته تا رفتار زمان اجرا را روشن کند. ( I9915c ) - On Android Multiuser, execute commands as root only on rooted devices. ( I88b44 )
نسخه ۱.۴.۰-آلفا۰۵
۱۳ نوامبر ۲۰۲۴
androidx.benchmark:benchmark-*:1.4.0-alpha05 منتشر شد. نسخه 1.4.0-alpha05 شامل این کامیتها است.
رفع اشکالات
- Fixed an issue on API 34+ where
CompilationMode.None()would have inconsistent performance not representative of initial, worst case performance. This works around a platform change which allows ART's compilation stateverifyto partially compile apps (only affecting class loading) shortly after first launch. ( Ie48d0 ) - مشکلی که باعث میشد ردپاهایی (بهویژه کوتاه) ثبت شوند که اندازهگیری را از معیارهای داخلی Macrobenchmark گزارش نمیدادند، برطرف شد، زیرا نام فرآیند در ردپای Perfetto کوتاه شده بود. اکنون macrobenchmark با جستجوی نام بسته کوتاه شده در تمام پرسوجوهای داخلی، علاوه بر نام بسته مورد انتظار، این مشکل را حل میکند. توجه داشته باشید که پیادهسازیهای سفارشی
TraceMetricیا سایر فراخوانیکنندههای مستقیمPerfettoSession.queryمیتوانند همین رفتار را با تغییرprocess.name LIKE "$packageName"در یک پرسوجوی Perfetto به(process.name LIKE "$packageName" OR process.name LIKE "$(packageName.takeLast(15))")پیادهسازی کنند. ( I5bf01 ، b/377565760 )
نسخه ۱.۴.۰-آلفا۰۴
۳۰ اکتبر ۲۰۲۴
androidx.benchmark:benchmark-*:1.4.0-alpha04 منتشر شد. نسخه 1.4.0-alpha04 شامل این کامیتها است.
ویژگیهای جدید
- (Experimental) Enable Baseline Profile generation, and benchmarking on apps installed to a secondary user, for example any app on headless Android Auto devices. This support has been tested in some scenarios, but let us know with a bug if it doesn't work for you. ( I9fcbe , b/356684617 , b/373641155 )
رفع اشکالات
-
isProfileableis now always overridden in benchmark builds, andisDebuggableis also now always overridden in both benchmark andnonMinified(baseline profile capture) builds. ( I487fa , b/369213505 ) - Fixes compilation detection on some physical devices prior to API 28 - affects json
context.compilationMode, as well as behavior ofandroidx.benchmark.requireAot=true(which no longer incorrectly throws) ( Ic3e08 , b/374362482 ) - In
CpuEventCountermetrics, throw if invalid measurements are observed (eg instructions/cpucycles==0) ( I8c503 )
نسخه ۱.۴.۰-آلفا۰۳
۱۶ اکتبر ۲۰۲۴
androidx.benchmark:benchmark-*:1.4.0-alpha03 منتشر شد. نسخه 1.4.0-alpha03 شامل این کامیتها است.
تغییرات API
- Macrobenchmark :
ArtMetricرا اضافه میکند که میتواند برای بررسی پوشش پروفایل یا عملکرد کلی Android RunTime استفاده شود. تعداد و مدت زمان کل JIT، کلاس init (در صورت وجود) و تأیید کلاس را ثبت میکند. علاوه بر این،CaptureInfoتغییر میدهد تا نسخه اصلی ART اختیاری را با پیشفرض در بر بگیرد. ( I930f7 ) - برای نمایش پایداری در یک اجرای معیار مشخص،
coefficientOfVariationبه خروجی JSON معیار اضافه کنید. ( Ib14ea )
رفع اشکالات
- Fixed
CollectBaselineProfileTaskwhen AVD device has spaces in it. ( Ia0225 , b/371642809 ) - رفع احتمالی خطاهای ناشی از استثنائات
StartupMode.COLD:Package <packagename> must not be running prior to cold start!اکنون،MacrobenchmarkScope.killProcess()(شامل یک اجرا قبل از هر تکرار، که برای پیادهسازی رفتارStartupMode.COLDاستفاده میشود) منتظر میماند تا تأیید کند که فرآیندهای برنامه همگی متوقف شدهاند. ( I60aa6 , b/351582215 ) - مشکل نمایش خطای UNLOCKED_ در برخی از شبیهسازهای روتشده برطرف شد. ( Ic5117 )
- This library now uses JSpecify nullness annotations , which are type-use. Kotlin developers should use the following compiler argument to enforce correct usage:
-Xjspecify-annotations=strict(this is the default starting with version 2.1.0 of the Kotlin compiler). ( I7104f , b/326456246 )
نسخه ۱.۴.۰-آلفا۰۲
۲ اکتبر ۲۰۲۴
androidx.benchmark:benchmark-*:1.4.0-alpha02 is released. Version 1.4.0-alpha02 contains these commits .
تغییرات API
- وظایف Gradle به
lockClocksوunlockClocksبه جای اینکه در سطح بالا در دسترس باشند، به پروژههای بنچمارک منتقل شدند. این تغییر ضروری بود زیرا متأسفانه هیچ راهی برای ثبت این موارد به عنوان اقدامات سطح بالا بدون شکستن انزوای پروژه وجود ندارد. ( I02b8f , b/363325823 )
رفع اشکالات
-
BaselineProfileRuleاکنون با ارسال سیگنال به هر فرآیند در حال اجرا در انتهای بلوک برای تخلیه پروفایلها، پروفایلهای برنامههای چند فرآیندی را جمعآوری میکند. اگر یک کامپایل مبتنی بر پروفایل هرگز با موفقیت فرآیندی را برای پخش پیدا نکند، کامپایل با شکست مواجه میشود، زیرا وجود دادههای پروفایل در آن غیرمنتظره است. علاوه بر این، یک آرگومان ابزار دقیق برای کنترل مدت زمان انتظار تخلیه اضافه شده است:androidx.benchmark.saveProfileWaitMillis( I0f519 ، b/366231469 ) - از بنچمارک
1.3.2: مشکل آزمایشگاه تست فایربیس (FTL) که نمیتوانست فایلهای نتیجه Baseline Profile یا Macrobenchmark را از افزونه Gradle Baseline Profile دریافت کند، برطرف شد. ( I2f678 ، b/285187547 )
برای استفاده از FTL، افزونه را به ماژول پروفایل پایه در بلوک افزونه اعمال کنید، با:
plugins {
...
id("com.google.firebase.testlab")
}
و سپس آزمایشگاه تست فایربیس را با دستور زیر پیکربندی کنید:
firebaseTestLab {
// Credentials for FTL service
serviceAccountCredentials.set(file("credentials.json"))
// Creates one or more managed devices to run the tests on.
managedDevices {
"ftlDeviceShiba34" {
device = "shiba"
apiLevel = 34
}
}
// Ensures the baseline profile is pulled from the device.
// Note that this will be automated as well later with aosp/3272935.
testOptions {
results {
directoriesToPull.addAll("/storage/emulated/0/Android/media/${android.namespace}")
}
}
}
همچنین دستگاه FTL ایجاد شده باید به افزونه پروفایل پایه اضافه شود:
baselineProfile {
managedDevices += "ftlDeviceShiba34"
useConnectedDevices = false
}
نسخه ۱.۴.۰-آلفا۰۱
۱۸ سپتامبر ۲۰۲۴
androidx.benchmark:benchmark-*:1.4.0-alpha01 is released. Version 1.4.0-alpha01 contains these commits .
ویژگی جدید - بینشهای راهاندازی برنامه
- نسخه اولیه بینشهای راهاندازی برنامه را میتوان در Macrobenchmark فعال کرد. ( 09fae38 )
برای فعال کردن در یک بنچمارک راهاندازی:
@Test
fun startup {
macrobenchmarkRule.measureRepeated(
…
packageName = "com.example.my.application.id"
metrics = listOf(StartupTimingMetric()),
iterations = 5,
startupMode = StartupMode.COLD,
compilationMode = CompilationMode.None(),
experimentalConfig = ExperimentalConfig(startupInsightsConfig = StartupInsightsConfig(isEnabled = true))
) {
scope.startActivityAndWait(...)
}
}
سپس اجرای بنچمارک راهاندازی شما، ردیابی را برای یافتن مشکلات رایج تجزیه و تحلیل میکند و آنها را پس از معیارها در خروجی تست استودیو در برگه بنچمارک چاپ میکند، مثلاً:
StartupBenchmark_startup[startup=COLD,compilationMode=None]
├── Metrics
│ ├── timeToFullDisplayMs min 1,147.2, median 1,208.8, max 1,307.4
│ └── timeToInitialDisplayMs min 1,147.2, median 1,208.8, max 1,307.4
├── App Startup Insights
│ ├── App in debuggable mode (expected: false)
│ │ └── seen in iterations: 0(true) 1(true) 2(true) 3(true) 4(true) 5(true) 6(true) 7(true) 8(true) 9(true)
│ ├── Potential CPU contention with another process (expected: < 100000000ns)
│ │ └── seen in iterations: 4(105022546ns)
│ └── Main Thread - Binder transactions blocked (expected: false)
│ └── seen in iterations: 7(true)
└── Traces
└── Iteration 0 1 2 3 4 5 6 7 8 9
این ویژگی هنوز در حال توسعه است و پیشرفتهایی در مستندات و قابلیت توسعه آن در راه است، اما از بازخورد شما استقبال میشود.
ویژگیهای جدید
- ویژگی gradle به نام
androidx.baselineprofile.suppressWarningsبرای سرکوب همه هشدارهای پروفایل پایه اضافه شد. ( 314153a ) - معیارهای میکروبنچ اکنون در ردپاهای Perfetto به عنوان شمارنده نمایش داده میشوند. ( 3214854 )
- اسکریپتهای آزمایشی برای غیرفعال کردن jit (نیازمند روت / راهاندازی مجدد در زمان اجرا) و تنظیم مجدد وضعیت عملکرد/تست دستگاه اضافه کنید. این موارد در حال حاضر به عنوان وظایف gradle منتشر نشدهاند. ( 7c3732b )
- Added benchmark argument to skip tests when running on emulator. When
automaticGenerationDuringbuild is enabled, benchmarks will also trigger baseline profile generation. This will fail, if emulators are used. With the new argumentskipBenchmarksOnEmulatorwe can instead skip the test. ( 0c2ddcd ) - تغییر رویداد perf، منطق را برای اجرا در API 23+ ( 2550048 ) فعال میکند.

نسخه ۱.۳.۰
۲۱ آگوست ۲۰۲۴
androidx.benchmark:benchmark-*:1.3.0 منتشر شد. نسخه ۱.۳.۰ شامل این کامیتها است.
تغییرات میکروبنچمارک از نسخه ۱.۲.۰
- ردیابی متد به طور پیشفرض در میکروبنچمارکها هنگام اجرا روی اکثر دستگاهها فعال است.
- ردیابی روش به عنوان یک مرحله جداگانه، پس از اندازهگیریها اجرا میشود - این امر باعث میشود اندازهگیریهای دقیق و ردیابی روشها هر دو از یک اجرای معیار واحد خروجی گرفته شوند.
- ردیابی روش در برخی از نسخههای سیستم عامل اندروید و ART بر مراحل اندازهگیری بعدی تأثیر میگذارد - در این نسخهها، ردیابی روش به طور پیشفرض خاموش است و یک هشدار در خروجی استودیو چاپ میشود.
- Main thread benchmarks and ANRs
- برای معیارهای نخ رابط کاربری (مثلاً آنهایی که با رابطهای کاربری Compose/View تعامل دارند)
measureRepeatedOnMainThreadاضافه شد تا از ANRها هنگام اجرا برای چند ثانیه جلوگیری شود. - اگر انتظار برود که از مهلت اجتناب از ANR تجاوز کند، ردیابیهای متد نادیده گرفته میشوند. برای غیرفعال کردن این رفتار،
androidx.benchmark.profiling.skipWhenDurationRisksAnrرا روی false تنظیم کنید (برای اجراهای CI توصیه نمیشود، زیرا ANRها میتوانند در اجراهای طولانی CI مشکل ایجاد کنند).
- برای معیارهای نخ رابط کاربری (مثلاً آنهایی که با رابطهای کاربری Compose/View تعامل دارند)
- کوچکسازی
- قوانین پروگارد تعبیهشده برای بهبود میکروبنچمارکینگ با فعالسازی کوچکسازی
- Minification/R8 در یک ماژول کتابخانهای به AGP 8.3 نیاز دارد و میتواند از طریق
android.buildTypes.release.androidTest.enableMinificationدرbuild.gradleشما فعال شود. - API آزمایشی
BlackHole.consume()برای جلوگیری از حذف کدهای مرده اضافه شد ( If6812 , b/286091643 )
- معیارها
- Experimental cpu event counter feature (metrics from
perf_event_open, which requires root on most versions of the platform), access viaInstrumentationArgumentandroidx.benchmark.cpuEventCounter.enable(can be set totrue), andandroidx.benchmark.cpuEventCounter.eventscan be set eg to (Instructions,CpuCycles). This should be supported on some userdebug emulators, but support has not been tested across all available emulators
- Experimental cpu event counter feature (metrics from
تغییرات MACRObenchmark از نسخه ۱.۲.۰
- Method tracing overhaul for macrobenchmarks.
- Now method traces are scoped to the duration of the
measureBlock, and can capture multiple sessions if the process starts multiple times. - پیش از این، ردیابی متد فقط برای بنچمارکهای
StartupMode.COLDکار میکرد و برایmeasureBlocksکه فرآیند هدف را مجدداً راهاندازی نمیکردند، چیزی ثبت نمیکرد. - ردیابیهای متد اصلاحشده در ماکروبنچمارک همسطح میشوند، بنابراین ردیابیهای متد باید بهطور کامل ثبت و معتبر باشند، حتی در دستگاههای کندتر. ( I6349a ، b/329904950 )
- Now method traces are scoped to the duration of the
- Correctly dump ART profile during individual
warmUpiterations when process is killed soCompilationMode.Partial(warmup=N)measurements are more accurate. ( I17923 ) - پیام خرابی پخش Drop Shader
- پیشنهادهای اشکالزدایی برای حذف پیام خطای پخش سایهزن اضافه شد
- دو آرگومان ابزار دقیق برای لغو رفتار رها کردن سایهزن برای حل مشکل خرابیها هنگام بنچمارکگیری از برنامهها بدون
ProfileInstaller1.3 اضافه کنید:-
androidx.benchmark.dropShaders.enable=true/false: can be used to skip all shader dropping (including that done inStartupMode.Coldlaunches), esp when benchmarking apps that don't yet use profileinstaller 1.3 -
androidx.benchmark.dropShaders.throwOnFailure=true/false: can be used to tolerate failures when trying to drop shaders, for example when benchmarking apps without profileinstaller 1.3 ( I4f573 )
-
- Added experimental
MacrobenchmarkRule#measureRepeatedvariant which takes a customPerfettoConfigfor fully customized Perfetto trace recording. Note that incorrectly configured configs may cause built in Metric classes to fail. ( Idfd3d , b/309841164 , b/304038384 ) - قبل از اجرای یک Macrobenchmark، کارهای dexopt پسزمینه را لغو کنید تا تداخل کاهش یابد. ( I989ed )
- Macrobenchmark اکنون ۱ ثانیه منتظر میماند تا برنامهی هدف، پروفایل ART را پاک کند (قبلاً ۵۰۰ میلیثانیه منتظر میماند). ( I85a50 ، b/316082056 )
- TraceSectionMetric overhaul
- توجه : تغییرات
TraceSectionMetricزیر میتواند بر خروجیها در استفاده از CI تأثیر بگذارد و ممکن است ناپیوستگی ایجاد کند یا تجزیه را مختل کند. - اکنون Sum پیشفرض است، زیرا بیشتر استفاده از این معیار برای رویدادهای تکراری است و first دادهها را در این موارد حذف میکند.
- تغییر یافته تا قابل تنظیمتر باشد، با حالتهای موجود بیشتر
- نام حالتها اکنون در نام خروجی متریک (در استودیو و JSON) تعبیه شدهاند.
- اکنون از برشهای ایجاد شده با استفاده از
Trace.{begin|end}AsyncSectionپشتیبانی میکند.
- توجه : تغییرات
- معیارها
- Power - Added
PowerMetric.deviceSupportsHighPrecisionTracking,PowerMetric.deviceBatteryHasMinimumCharge()andPowerMetric.deviceSupportsPowerEnergy() - برای مطابقت با نوع بازگشتی،
Metric.getResultبهgetMeasurementsتغییر نام داد. - برچسبهای log.w / exception به همه خطاهای تشخیص راهاندازی اضافه شد. این کار رفتار فعلی را تغییر نمیدهد (بنابراین برخی خطاها رخ میدهند و برخی دیگر به طور خاموش در تشخیص راهاندازی ناموفق هستند)، فقط آن را قابل فهمتر میکند. به طور کلی مواردی که
Log.w()و معیارهای راهاندازی را گزارش نمیکنند، مواردی هستند که رویدادهای غیر فریمی از دست رفتهاند، هنگام شناسایی راهاندازی به جز اطلاعات زمانبندی فریم (از برشهای UI/RT) استثناهایی رخ میدهد. ( Id240f ، b/329145809 ) - اندازهگیری
frameCountبهFrameTimingMetricاضافه شد تا به کشف سناریوهایی که در آنها اندازهگیریها به دلیل تغییر تعداد فریمهای تولید شده تغییر میکنند، کمک کند (انیمیشنهای جدید اضافه شد، مشکلات نامعتبرسازی برطرف شد). ( I1e5aa ) - توضیح داده شد که
frameOverrunMsمعیار ترجیحی برای ردیابی در صورت وجود در اسناد است و دلیل آن چیست. ( I18749 ، b/329478323 ) - Fixes issue where unterminated frames at the beginning and end of the trace could be paired together, which would incorrectly report as a single extremely long frame. ( I39353 , b/322232828 )
- خطای
FrameTimingMetricرا هنگام تولید نشدن فریمها بهبود بخشید، و همیشه هنگام عدم موفقیت در تجزیه متریک، لینک را برای ردیابی خروجی دهید تا به تشخیص مشکل کمک کند. ( I956b9 ) - مشکل کرش کردن
FrameTimingMetricکه باعث میشد نتواند شناسه فریم را تجزیه کند، مخصوصاً در برخی از دستگاههای OEM، برطرف شد. ( Ia24bc ، b/303823815 ، b/306235276 ) - سختگیری در بررسیها در
FrameMetricsکاهش یافت و جزئیات بیشتری به پیامهای خطا اضافه شد. ( Iadede )
- Power - Added

سایر تغییرات قابل توجه از زمان ۱.۲.۰
- ردیابی ضبط
- کاهش خطای EXITCODE 2 هنگام شروع perfetto از یک خطا به هشدار ثبت شده
- فعال کردن ردیابی AIDL به صورت پیشفرض در بنچمارکها (نیازمند API 28) ( Ia0af2 ، b/341852305 )
- Enable porter tag tracing by default in benchmarks. This captures, for example, wakelock tracepoints. ( Icfe44 , b/286551983 )
- افزایش زمان شروع ضبط ردیابی برای جلوگیری از خرابی هنگام شروع ردیابی در دستگاههای کندتر ( I98841 ، b/329145808 )
- Added public API
PerfettoTraceProcessor.Session.queryMetricsAPIs with JSON, textproto, and proto binary (undecoded) variants. These allow you to query metrics built intoTraceProcessor( I54d7f , b/304038382 ) - فعال کردن شروع مسدودسازی در رکورد ردیابی Perfetto برای کاهش خطر از دست رفتن دادهها در ابتدای ردیابی. فقط در API 33+ پشتیبانی میشود. ( Ie6e41 ، b/310760059 )

- اطلاعات اضافی در زمینه معیار در خروجی JSON اضافه شد:
-
context.artMainlineVersion- integer version of Art mainline module (if present on device,-1otherwise) -
context.build.id- برابر با android.os.Build.ID -
context.build.version.codename- Equals android.os.Build.VERSION.CODENAME -
context.build.version.abbreviatedCodename- corresponds to first letter of pre-release codename (including on release builds) ( Ie5020 )
-
- Added
profilerOutputlist to JSON output for easier tooling around profiling traces (eg Perfetto, Method traces) ( I05ddd , b/332604449 ) - Added a warning when Android Test Orchestrator is used in benchmark modules, as this will cause per-module output JSON files to be repeatedly overwritten. ( Ia1af6 , b/286899049 )
- Throw when filenames are longer than 200 chars to avoid unclear crashes when writing or post-processing files. ( I4a5ab )

رفع اشکالات
- Fix
androidx.benchmark.cpuEventCounterproducing corrupt values for non-Instruction events ( I7386a , b/286306579 ) - Fix
resumeTiming/runWithTimingDisabledto respect metric priority order, and significantly reduce impact of lower priority metric pause/resume on higher priority metric results. For example, if using cpu perf counters viacpuEventCounter.enableinstrumentation argument, timeNs is no longer significantly reduced when pause/resume occur. ( I39c2e , b/286306579 , b/307445225 ) - Reduced chance of stack sampling causing
measureRepeatedOnMainThreadfrom hitting main thread hard timeout by moving stack sampling conversion off main thread. ( I487a8 , b/342237318 ) - Removed manual outlining of access to new platform APIs since this happens automatically via API modeling when using R8 with AGP 7.3 or later (eg R8 version 3.3) and for all builds when using AGP 8.1 or later (eg D8 version 8.1). Clients who are not using AGP are advised to update to D8 version 8.1 or later. See this article for more details. ( I9496c , b/345472586 )
- Added agp version check to send package name as instr arg. Previous to AGP 8.4.0 the target app package name cannot be send to the instrumentation app via instrumentation arguments. ( 0c72a3f )

تغییرات API
- Renamed
MethodTracing.affectsMeasurementOnThisDevicetoAFFECTS_MEASUREMENT_ON_THIS_DEVICEfor consistency. ( I1bdfa ) - Added experimental
BlackHole.consume()api to prevent dead code elimination in microbenchmarks. ( If6812 , b/286091643 ) - Microbenchmark will now correctly throw to prevent method tracing from interfering with measurements. This occurs on certain devices when method tracing is forced on (via instrumentation args or
MicrobenchmarkConfig), and if a measurement is attempted after a method trace. Affected devices are running API 26-30 or certain ART mainline module versions affected by this interference, and can be detected at runtime viaProfilerConfig.MethodTracing.affectsMeasurementOnThisDevice. ( Iafb92 , b/303660864 )

ویژگیهای جدید
- Adds public API
PerfettoTraceProcessor.Session.queryMetricsAPIs with JSON, textproto, and proto binary (undecoded) variants. These allow you to query metrics built into TraceProcessor ( I54d7f , b/304038382 ) - Added
profilerOutputto JSON output for easier tooling around profiling traces (eg perfetto, method traces). ( I05ddd , b/332604449 ) - Added power tag to benchmark Perfetto Config. This captures, for example, wakelock tracepoints. ( Icfe44 , b/286551983 )
- Added inst argument
androidx.benchmark.profiling.skipWhenDurationRisksAnr, can be set to false to avoid skipping method traces when expected duration may cause an ANR - strongly recommended to avoid in CI runs. - Added experimental inst argument
androidx.benchmark.profiling.perfCompare.enable, set this to true to run comparison timing between measurement and profiling phases. Useful in eg evaluating overhead of method tracing. ( I61fb4 , b/329146942 )
تغییرات API
- Changed
TraceSectionMetric.Modeto sealed class to enable future expansion without breaking exhaustive when statements ( I71f7b ) - Added
TraceSectionMetric.Mode.Averageand.Count, and reordered args so the more common argument (mode) was earlier in the arg list, reducing need for specifying parameter names. ( Ibf0b0 , b/315830077 , b/322167531 ) - Renamed
Metric.getResulttogetMeasurementsto match return type ( I42595 )
رفع اشکالات
- Fix to ensure benchmarks use generated baseline profiles when
automaticGenerationDuringBuildis off ( Ic144f , b/333024280 ) - Fix
BaselineProfilegradle plugin property overrides to enable baseline profile generation and benchmarking when customizing anonMinifiedor benchmark build type. ( Ib8f05 , b/324837887 ) - Fixed method traces flush in macrobenchmark, so that method traces should be fully captured and valid, even on slower devices. ( I6349a , b/329904950 )
- Enable blocking start on Perfetto trace record to reduce risk of missing data at beginning of trace. Only supported on API 33+. ( Ie6e41 , b/310760059 )
- Added a warning when Android Test Orchestrator is used in benchmark modules, as this will cause per-module output JSON files to be repeatedly overwritten. ( Ia1af6 , b/286899049 )
- Force ',' (comma) thousands separators for consistency in Studio output, ignoring device locale ( I3e921 , b/313496656 )
-
TraceSectionMetricnow supports slices created usingTrace.{begin|end}AsyncSection. ( I91b32 , b/300434906 ) - Added log.w / exception labels to all startup detection failures. This does not change current behavior (so some errors throw, and others silently fail to detect the startup), just makes it more understandable. Generally the ones that
Log.w()and fail to report startup metrics are those where non-frame events are missing, exceptions are thrown when startup is detected except for frame timing information (from UI/RT slices). ( Id240f , b/329145809 ) - Cancel background dexopt jobs before running a Macrobenchmark to reduce interference. ( I989ed )
- Added
frameCountmeasurement toFrameTimingMetricto aid in discovery of scenarios where measurements change because the number of frames produced changed (new animations added, invalidation issues fixed). ( I1e5aa ) - Clarified that
frameOverrunMsis the preferred metric for tracking when available in docs, and why. ( I18749 , b/329478323 )

تغییرات API
- Renamed
MicrobenchmarkConfigboolean parameters to avoid unnecessary word 'should' ( Ia8f00 , b/303387299 ) - Added
BenchmarkRule.measureRepeatedOnMainThreadso main thread benchmarks (eg ones touching Views or Compose UIs) can avoid triggering ANRs, especially during large suites in CI. ( I5c86d ) - Added
FrameTimingGfxInfoMetric, an experimental alternate implementation ofFrameTimingMetricwith measurements coming directly from the platform, rather than extracted from the Perfetto trace. ( I457cb , b/322232828 ) - Add the ability to dump an ART profile during individual
warmUpiterations. ( I17923 ) - Several changes to
TraceSectionMetricAPI:- Add
Mode.Min,Mode.Max - Add label argument to override section name as metric label
- Added mode name to output to clarify metric meaning
- Changed default to sum, as most usage of this metric is for repeated events Be aware of this changes in CI usage, as it may create discontinuities or break parsing. ( Ic1e82 , b/301892382 , b/301955938 )

- Adjusted data source timeouts to attempt to fix
java.lang.IllegalStateException: Failed to stop [ProcessPid(processName=perfetto, pid=...)]( I8dc7d , b/323601788 ) - Add two instrumentation arguments for overriding shader dropping behavior to workaround crashes when benchmarking apps without
ProfileInstaller1.3:-
androidx.benchmark.dropShaders.enable=true/false: can be used to skip all shader dropping (including that done inStartupMode.Coldlaunches), esp when benchmarking apps that don't yet use profileinstaller 1.3 -
androidx.benchmark.dropShaders.throwOnFailure=true/false: can be used to tolerate failures when trying to drop shaders, for example when benchmarking apps without profileinstaller 1.3 ( I4f573 )
-
- Skip method tracing on UI thread when expected to take longer than a few seconds, and cleanup method traces when throwing. ( I6e768 )
- Throw when filenames are longer than 200 chars to avoid unclear crashes when writing or post-processing files. ( I4a5ab )
- Fixes issue where unterminated frames at the beginning and end of the trace could be paired together, which would incorrectly report as a single extremely long frame. ( I39353 , b/322232828 )
- Use
--skip verificationon API 30+ when reinstalling a package on API 30-33 to clear ART profiles on user builds. This helps bypass Play Protect warnings that cause failures on some class of devices. ( Ic9e36 ) - Use
am force-stopto kill apps when not a system app like System UI or Launcher. ( I5e028 ) - Macrobenchmark now waits for

تغییرات مهم از زمان ۱.۱.۰
Baseline Profiles
- New Baseline Profile Gradle Plugin automates capturing and including baseline profiles in your test and build workflow.

packageName, and drive your app
- Just specify
- For libraries generating baseline profiles, you can now filter the rules generated either in code (
BaselineProfileRule.collectargument), or even more simply in the gradle plugin - رفع اشکالات
- Fixed baseline profile collection on Android U+ ( Id1392 , b/277645214 )
Macrobenchmark
- گردآوری
- Macrobenchmark now correctly fully resets compilation state for each compile - this requires reinstalling the APK prior to Android 14, so benchmarking on Android 14+ is strongly recommended if you want to persist state (like user login) in what's being measured.
- You can also work around this by controlling app compilation separately, and skipping compilation with
CompilationMode.Ignore()or instrumentation argument
Instrumentation Arguments
- Support for
androidx.benchmark.dryRunMode.enableinstrumentation argument, (already available in microbenchmark) for quicker validation runs (eg when creating the benchmark, or in presubmit) - Support for
androidx.benchmark.profiling.mode=StackSamplingandMethodTracing. - Added
androidx.benchmark.enabledRulesto allow runtime filtering baseline profile vs macrobenchmark rule tests - Added
androidx.benchmark.perfettoSdkTracing.enableargument to enable tracing with tracing-perfetto, eg Compose recomposition tracing. Note that when used withStartupMode.COLD, timing will be significantly affected as the tracing library is loaded and enabled during app startup.
- Support for
الزامات
- Macrobenchmark now requires
ProfileInstaller1.3.0 or greater in the target app, to enable profile capture / reset, and shader cache clearing.

- Skip battery level check for devices without battery (micro and macro)
- Improved file output, with more clear errors for invalid output directories, and safer defaults
- Improved stability of
StartupMode.COLDby consistently dropping the shader cache (also exposed viaMacrobenchmarkScope.dropShaderCache) - Fixed leanback fallback for
startActivityAndWait.
Microbenchmark
- ویژگیها
- Profiling was moved to a separate phase, after other metrics, so one test run can display both accurate timing and profiling results.
- Experimental APIs
- Added experimental
MicrobenchmarkConfigAPI for defining custom metrics and configuring tracing and profiling. Can be used to capture method traces, or capture tracepoints (but be aware of tracing overhead). - Added experimental APIs for controlling
BenchmarkStateseparately fromBenchmarkRule, without JUnit - Added experimental
PerfettoTracerecord to enable capturing Perfetto traces, with custom configuration, separate from benchmark APIs.
- Added experimental
- رفع اشکالات
- Workaround missing leading whitespaces in Android Studio benchmark output.
- Fix issue where warnings could fail to print in Android Studio benchmark output.
- Fixed
SampledProfilingcrash on Android 13 (API 33) and higher. - Massively improved performance of

Version 1.2.0-alpha08
۷ دسامبر ۲۰۲۲
androidx.benchmark:benchmark-*:1.2.0-alpha08 is released. Version 1.2.0-alpha08 contains these commits.
تغییرات API
- Added experimental new APIs
PerfettoTrace.record {}andPerfettoTraceRuleto capture Perfetto traces (also known as System Traces) as part of a test, to inspect test behavior and performance. ( I3ba16 ) -
BaselineProfileRulenow accepts a filter predicate instead of a list of package prefixes. This gives the test full control on filtering. ( I93240 ) - Add an experimental API
BaselineProfileRule.collectStableBaselineProfilewhich waits until a baseline profile is stable for N iterations. ( I923f3 ) - Add the ability to specify an output file name prefix when generating baseline profiles using
BaselineProfileRule. ( I7b59f , b/260318655 )
رفع اشکالات
- Improve safety of file output writing, which should prevent output files from silently not being written / appended, especially on API 21/22. ( If8c44 , b/227510293 )
- Fix
simpleperftrace output to create and place the file correctly. This should also more generally fix issues where a file is unsuccessfully pulled by gradle. ( I12a1c , b/259424099 ) - Improve profileinstaller error message printed when profileinstaller is too old. This now tells you to update profileinstaller version (1.2.1) for measuring baseline profiles on API 31 through 33, instead of saying it's not supported. ( Ia517f , b/253519888 )
- Fix several shell command failures onerror message Print needed API <=23, including failed perfetto capture binary setup and trace capture failures ( Ib6b87 , b/258863685 )
- Automatically sort generated profile rules to minimize the number of changes as they change over time (when checking-in profile rules into source control). ( Ie2509 )
- Fixed crash on unrooted builds below Android 13 (API 33) with message
Expected no stderr from echo 3 > /proc/sys/vm/drop_caches( I6c245 , b/259508183 )
Known Issues - MacrobenchmarkScope.dropShaderCache() may crash due to a missing broadcast registry in profileinstaller manifest, which has not yet been released. ( I5c728 , b/258619948 ) To workaround the issue in profileinstaller:1.3.0-alpha02 , add the following to your application's (not your benchmark's) AndroidManifest.xml:

نسخه ۱.۲.۰-آلفا۰۷
۹ نوامبر ۲۰۲۲
androidx.benchmark:benchmark-*:1.2.0-alpha07 is released. Version 1.2.0-alpha07 contains these commits.
تغییرات API
- Adds
PowerMetricAPI for measuring energy and power in Macrobenchmarks. ( Ife601 , b/220183779 ) - Fixed
MacrobenchmarkScope.dropShaderCache()to actually drop the shader cache. This removes roughly 20ms of noise fromStartupMode.COLDbenchmarks, as shaders are now consistently cleared each iteration. Previously,Partialcompilation using warmup iterations would report incorrectly fast numbers, as shader caching was more likely to happen during warmup. This fix requires either a rooted device, or usingprofileinstaller:1.3.0-alpha02in the target app. ForProfileInstallerlibrary's API changes, please refer to ProfileInstaller 1.30-alpha02 page. ( Ia5171 , b/231455742 ) - Added
TraceSectionMode("label", Mode.Sum), allowing measurement of total time spent on multiple trace sections with the same label. For instance,TraceSectionMetric("inflate", Mode.Sum)will report a metricinflateMsfor the total time in a macrobenchmark spent on inflation. Also removed API 29 requirement, asTraceSectionMetricworks together withandroidx.tracing.Traceback to lower API levels, with the use offorceEnableAppTracingwithin the target app. ( Id7b68 , b/231455742 )
رفع اشکالات
- Improved safety of all internal shell commands by validating all output/errors. ( I5984d , b/255402908 , b/253094958 )
- Specify device in baseline profile
adb pullcommand, so the pull command can be simply copied if multiple devices are connected (up to one emulator) ( I6ac6c , b/223359380 ) - Add error if macrobenchmark test apk isn't set up as self-instrumenting. This error prevents macrobenchmarking from within the target app's process. In process, macrobench wouldn't be able to compile/kill/cold start the app, or control its own permissions ( I4279b )
- Fixed an issue in
measureRepeated()whereStartupMode.COLDwouldn't kill the target process aftersetupBlock. NowsetupBlockinteracting with the app will not leave the app process running, and an invalid cold start measurement. ( I8ebb7 )
نسخه ۱.۲.۰-alpha06
۲۴ اکتبر ۲۰۲۲
androidx.benchmark:benchmark-*:1.2.0-alpha06 is released. Version 1.2.0-alpha06 contains these commits.
تغییرات API
-
BaselineProfileRuleno longer requires root on Android 13 (API 33), and is no longer experimental. ( Ie0a7d , b/250083467 , b/253094958 )- This change also fixes how profiles from an app are flushed to disk on unrooted devices, but requires updating the target app's profileinstaller dependency.
- To use
BaselineProfileRuleorCompilationMode.Partial(warmupIterations)on an unrooted device, you must also update your target app to useandroidx.profileinstaller.profileinstaller:1.3.0-alpha01. This enables flushing the profile to disk correctly, so that it can be compiled/extracted.
رفع اشکالات
- Fixes
SampledProfilingcrash on API 33+. ( I40743 , b/236109374 )
نسخه ۱.۲.۰-آلفا۰۵

FrameTimingMetricto listFrameOverrunas requiring API 31 instead of 29 ( I716dd , b/220702554 ) - Set iteration in
BaselineProfileRule, and throw clearly if target package not installed (was already done for MacrobenchmarkRule). ( Ic09a3 , b/227991471 )
نسخه ۱.۲.۰-آلفا۰۴
۲۱ سپتامبر ۲۰۲۲
androidx.benchmark:benchmark-*:1.2.0-alpha04 is released. Version 1.2.0-alpha04 contains these commits.
ویژگیهای جدید
Add support for
dryRunMode.enableinstrumentation argument to macrobenchmark (already available in micro) for faster local development, and validating app automation (eg in presubmit). This overrides iterations to 1, skips compilation, suppresses all configuration errors , and disables measurement .json file output. ( Ib51b4 , b/175149857 )On Gradle command line:
./gradlew macrobenchmark:cC -P android.testInstrumentationRunnerArguments.androidx.benchmark.dryRunMode.enable=trueIn build.gradle:
android { defaultConfig { testInstrumentationRunnerArgument 'androidx.benchmark.dryRunMode.enable', 'true' } }
رفع اشکالات
- Fixed
StartupTimingMetricto no longer require measured Activities to be launched throughMacrobenchmarkScope.startActivityAndWait(). This means the metric can pick up launches from eg notifications,Context.startActivity(), in-app Activity based navigation, or shell commands. ( Ia2de6 , b/245414235 ) - Fix bug where
startActivityAndWaitwould timeout trying to wait for launch completion on emulators by reducing strictness of frame detection. ( Ibe2c6 , b/244594339 , b/228946895 )
نسخه ۱.۲.۰-آلفا۰۳

- Added the ability to clear shader cache in
MacrobenchmarkScope. ( I32122 ) - Enables developer to configure display of metric type and detail desired subsystem categories. ( I810c9 )
- Previously an
UnsupportedOperationExceptionwas thrown in the benchmark if run on an unsupported device. Now UOE only occurs if the metric is used on the unsupported device (ie:PowerMetric.configure). ( I5cf20 , b/227229375 ) - Added
TotalPowerMetricandTotalEnergyMetricfor measuring total power and energy in each system category in macrobenchmarks. ( I3b26b , b/224557371 )
رفع اشکالات
- Fixed an issue where compiled methods were not correctly being reset between each macrobenchmark on unrooted builds. This unfortunately requires reinstalling the apk each iteration, which will clear application data for each macrobenchmark. ( I31c74 , b/230665435 )
- Fix trace recording crash on API 21/22 ( If7fd6 , b/227509388 , b/227510293 , b/227512788 )

Version 1.1.0-rc02
۱۱ مه ۲۰۲۲
androidx.benchmark:benchmark-*:1.1.0-rc02 is released. Version 1.1.0-rc02 contains these commits.
- Note that this release includes a behavior change, as apps are now fully reinstalled in between each benchmark to ensure accurate measurements.
Bug Fixes/Behavior Changes
Fixed an issue where app compilation was not correctly reset between macrobenchmarks, and not reset at all on unrooted builds. This fixes many cases where running multiple tests would result in
CompilationModehaving little to no effect on measurements. To workaround this problem, the target app is now fully reinstalling each test method, which will clear application data between each macrobenchmark. ( I31c74 , b/230665435 )As this prevents apps from setting up state before tests, it is now possible to skip compilation / reinstallation to enable working around this. You can for example fully compile the target with a shell command
cmd package compile -f -m speed <package>, and then bypass macrobenchmark's compilation step.Eg in Your macrobenchmark's build.gradle:
android { defaultConfig { testInstrumentationRunnerArgument 'androidx.benchmark.compilation.enabled, 'false' } }Or from the Gradle command line:
./gradlew macrobenchmark:cC -P android.testInstrumentationRunnerArguments.androidx.benchmark.compilation.enabled=falseMade it possible to share a module between macrobenchmarks and baseline profile generating tests by adding
androidx.benchmark.enabledRulesinstrumentation argument. Pass in 'Macrobenchmark', or 'BaselineProfile' to just run one type of test, eg when generatingBaselineProfileson an emulator. ( I756b7 , b/230371561 )Eg in Your macrobenchmark's build.gradle:
android { defaultConfig { testInstrumentationRunnerArgument 'androidx.benchmark.enabledRules', 'BaselineProfile' } }Or from the Gradle command line:
./gradlew macrobenchmark:cC -P android.testInstrumentationRunnerArguments.androidx.benchmark.enabledRules=BaselineProfile

NoSuchElementExceptioncaused by process names not being captured correctly in traces. ( Ib4c17 , b/218668335 )Use
PowerManagerfor thermal throttling detection on Q (API 29) and higher. This significantly reduces frequency of false positives in thermal throttling detection (benchmark retry after 90 second cooldown), and speeds up benchmarks significantly on user builds. It also provides throttle detection even when clocks are locked (if they're locked too high for the device's physical environment). ( I9c027 , b/217497678 , b/131755853 )Filter simpleperf sampled profiling to

Version 1.1.0-alpha13
۱۵ دسامبر ۲۰۲۱
androidx.benchmark:benchmark-*:1.1.0-alpha13 is released. Version 1.1.0-alpha13 contains these commits.
تغییرات API
- Add low-overhead System Tracing to microbench output on Android Q (API 29+). Note that this does not currently capture custom tracing (via
android.os.Traceorandroidx.tracingJetpack APIs) to avoid affecting results. This tracing should be useful in diagnosing instability, especially from sources outside the benchmark. ( I298be , b/205636583 , b/145598917 ) - Clarify
CompilationModesinto three classes - Full, None, Partial. Previously they were inconsistently named after compilation arguments (which we now treat as implementation details) and features. This makes the tradeoffs, potential combinations, and behavior across platform versions more clear. ( I3d7bf , b/207132597 ) - Setup and measure are now always in pairs, in order. You can now query the package name and iteration (though the iteration may be
nullin certain warmup scenarios). ( Id3b68 , b/208357448 , b/208369635 )

- Fixes multiple crashes in StackSampling profiling mode on emulators and non-rooted devices ( Icdbda , b/202719335 )
- Removed 0.5 second sleep at the end of each iteration - if you see missing metrics with this change, please file a bug. ( Iff6aa )
- Reduce chances of dropped data, and lower memory overhead from tracing ( Id2544 , b/199324831 , b/204448861 )
- Reduce trace size by ~40% by switching to compact sched storage format. ( Id5fb6 , b/199324831 )
- Updated implementations of startup metrics to always end at end of renderthread. This will be more contistent across platform versions, and more closely map to in-app measurements. ( Ic6b55 )

- Added JvmOverloads to multiple MacrobenchmarkScope methods for Java callers. ( I644fe , b/184546459 )
- Provide alternative MacrobenchmarkRule.measureRepeated function that uses a
Consumer<MacrobenchmarkScope>for idiomatic usage in Java language. ( If74ab , b/184546459 )
رفع اشکالات
- Fix for traces not starting early enough, and missing metric data. This is expected to fix "Unable to read any metrics during benchmark" exceptions that were caused by the library itself. ( I6dfcb , b/193827052 , b/200302931 )
- FrameNegativeSlack has been renamed to FrameOverrun to clarify its meaning - how much the frame went over its time budget. ( I6c2aa , b/203008701 )

1.1.0-alpha04 was cancelled before release due to a sporatic crash. b/193827052
تغییرات API
- Switched startActivityAndWait to invoke launch via
am start, which reduces the time of each measurement iteration by approximately 5 seconds, at the cost of no longer supporting intent parcelables. ( I5a6f5 , b/192009149
رفع اشکالات
- Reduce aggressiveness of thermal throttle detection, and recompute baseline if throttles are detected frequently. ( I7327b )
- Fixes FrameTimingMetric to work on Android S beta ( Ib60cc , b/193260119 )
- Use an
EmptyActivityto bring the target app out of a force-stopped state to better supportCompilationMode.BaselineProfile. ( Id7cac , b/192084204 ) - Changed trace file extension to
.perfetto-traceto match platform standard. ( I4c236 , b/174663039 ) - StartupTimingMetric now outputs the "fullyDrawnMs" metric to measure time until your application has completed rendering. To define this metric for your app, call Activity.reportFullyDrawn when your initial content is ready, such as when your initial list items are loaded from DB or network. (reportFullyDrawn method available without build version checks on ComponentActivity). Note that your test must run long enough to capture the metric (startActivityAndWait doesn't wait for reportFullyDrawn). ( If1141 , b/179176560 )
- Reduce cost of appending Ui metadata to traces by 50+ ms ( Ic8390 , b/193923003 )

نسخه ۱.۱.۰-آلفا۰۲
۱۸ مه ۲۰۲۱
Benchmark version 1.1.0-alpha02 brings a big component to benchmarking - Macrobenchmark. In addition to benchmark allowing you to measure CPU loops, macrobenchmark allows you to measure whole-app interactions like startup and scrolling, and capture traces. For more information see the library documentation .
androidx.benchmark:benchmark-*:1.1.0-alpha02 is released. Version 1.1.0-alpha02 contains these commits.
ویژگیهای جدید
Macrobenchmark artifacts added ( androidx.benchmark:benchmark-macro-junit4 and androidx.benchmark:benchmark-macro )
- Capture startup, scrolling/animation performance metrics from your app, locally or in CI
- Capture and inspect traces from within Android Studio
رفع اشکالات
- Workaround shell permissions issue with output directory on Android 12 (Note - may require updating Android Gradle Plugin to 7.0.0 canary and Android Studio to Arctic Fox (2020.3.1), to continue capturing output files on affected devices). ( Icb039 )
- Support configuration caching in BenchmarkPlugin ( 6be1c1 , b/159804788 )
- Simplified file output - on by default, in a directory that doesn't require
requestLegacyExternalStorage=true( 8b5a4d , b/172376362 ) - Fixes library printing logcat warnings about not finding JIT thread on platform versions where it is not present. ( I9cc63 , b/161847393 )
- Fix for reading device max frequency. ( I55c7a )
نسخه ۱.۱.۰-آلفا۰۱
June 10, 2020
androidx.benchmark:benchmark-common:1.1.0-alpha01 , androidx.benchmark:benchmark-gradle-plugin:1.1.0-alpha01 , and androidx.benchmark:benchmark-junit4:1.1.0-alpha01 are released. Version 1.1.0-alpha01 contains these commits.
New Features of 1.1
- Allocation Metric - Benchmarks now run an additional phase after warmup and timing, capturing allocation counts. Allocations can cause performance problems on older versions of the platform (140ns in O became 8ns in M - measured on Nexus5X, with locked clocks). This metric is displayed in Android Studio console output, as well as in the
- Profiling support - You can now capture profiling data for a benchmark run, to inspect why your code may be running slowly. Benchmark supports capturing either method tracing, or method sampling from ART. These files can be inspected with the Profiler inside Android Studio using File > Open .
- The Benchmark Gradle plugin now provides defaults for simpler setup:
-
testBuildTypeis set to release by default, to avoid using dependencies with code coverage built-in. The release buildType is also configured as the default buildType, which allows Android Studio to automatically select the correct build variant when opening a project for the first time. ( b/138808399 ) -
signingConfig.debugis used as the default signing config ( b/153583269 )
-
** Bug Fixes **
- Significantly reduced the warmup transition overhead, where the first measurement for each benchmark was artificially higher than others. This issue was more pronounced in very small benchmarks (1 microsecond or less). ( b/142058671 )
- Fixed
InstrumentationResultParsererror printed for each benchmark when running from command line. ( I64988 , b/154248456 )
مشکلات شناخته شده
- Command line, gradle invocations of Benchmark do not print out results directly. You can work around this by either running through Studio, or parsing the JSON output file for results.
- Benchmark reporting fails to pull the report from devices that have an app installed with an applicationId ending with either “android” or “download” (case insensitive). Users hitting this issue should upgrade the Android Gradle Plugin to 4.2-alpha01 or later.

New documentation has also been added for how to use the Benchmark library without Gradle, both for usage with different build systems (such as Bazel or Buck), and when running in CI. For more information, see Build benchmarks without Gradle and Run benchmarks in Continuous Integration .
ویژگیهای جدید
- Gradle plugin
- Now automatically disables test coverage, and sets the
AndroidBenchmarkRunnerby default ( b/138374050 ) - Added support for new AGP-based data copy, when running benchmarks and when using AGP 3.6+
- Now automatically disables test coverage, and sets the
- JSON format additions
- Output total benchmark test run time ( b/133147694 )
-
@Parameterizedbenchmarks that use a name string (for example@Parameters(name = "size={0},depth={1}")) now output parameter names and values per benchmark in the JSON output ( b/132578772 )
- Dry Run mode ( b/138785848 )
- Added a "dry run" mode for running each benchmark loop only once, to check for errors/crashes without capturing measurements. This can be useful eg for, for example, quickly running benchmarks in presubmit to check that they're not broken.
تغییرات API
- Module structure has changed, splitting the library ( b/138451391 )
-
benchmark:benchmark-junit4contains classes with JUnit dependency:AndroidBenchmarkRunner, andBenchmarkRule, both of which have moved into theandroidx.benchmark.junit4package -
benchmark:benchmark-commoncontains the rest of the logic, including the BenchmarkState API - This split will allow the library to support benchmarking without JUnit4 APIs in the future
-
- Configuration warnings are now treated as errors, and will crash the test ( b/137653596 )
- This is done to further encourage accurate measurements, especially in CI
- These errors can be reduced back to warnings with an instrumentation argument. For example:
-e androidx.benchmark.suppressErrors "DEBUGGABLE,LOW_BATTERY"
رفع اشکالات
- Errors when writing to external storage on Q devices provide more-descriptive messages, with suggestions of how to resolve the issue
- Screens are automatically turned on during benchmark runs, instead of failing when the screen is off

۶ ژوئن ۲۰۱۹
androidx.benchmark:1.0.0-alpha02 and androidx.benchmark:benchmark-gradle-plugin:1.0.0-alpha02 are released. The commits included in this version can be found here .
Note that we are treating the JSON schema as an API. We plan to follow the same stability constraints as other APIs: stable (with very rare exceptions) once in beta, and fixed in final release, with only additions in minor releases and changes/removals in major releases.
تغییرات API
Overhauled JSON schema. Further changes to the JSON schema are likely to be limited to additions:
- Reorganized the result object structure to support additional metric groups in the future ( b/132713021 )
