# Java 11+ APIs available through desugaring with the nio specification
Android Studio includes support for using a number of Java 11+ APIs without requiring a minimum API level for your app. This means that if you use an API introduced in Android 13 (API level 33) the code also works on all previous versions. Most APIs introduced to Android over the years are supported on Android 13. Through a process called[API desugaring](https://developer.android.com/studio/write/java8-support#library-desugaring), the DEX compiler (D8) allows you to include more standard language APIs in apps that support older versions of Android.
Java 11 support API desugaring comes in three flavors:
- The[minimal version](https://developer.android.com/studio/write/java11-minimal-support-table)includes only the`java.util.function`package and replacement classes for some Android framework concurrent collections that have known issues on old devices.
- The[default version](https://developer.android.com/studio/write/java11-default-support-table)is effectively an upgraded version of the Java 8 API desugaring updated to Java 11. It includes the`java.time`and`java.util.stream`packages in addition to everything in the minimal version.
- The[nio version](https://developer.android.com/studio/write/java11-nio-support-table)includes the`java.nio`package in addition to everything in the default version.
The following searchable table shows which Java 11+ libraries are available when you use the latest version of the Android Gradle plugin with the`coreLibraryDesugaring`dependency set to`com.android.tools:desugar_jdk_libs_nio:2.0.1`(see[API desugaring](https://developer.android.com/studio/write/java8-support#library-desugaring)for more information). Set this property in the`build.gradle`or`build.gradle.kts`file.

## `java.time`customizations
The following is a summary of potentially behavior-changing modifications to`java.time`that facilitate running the library on legacy Android devices.
- The method`Locale.getDefault()`is used instead of`Locale.getDefault(Locale.Category.FORMAT)`to look up user preferences. The latter method, as well as the`Category`enum, is new in JDK 8.
- Use`DateFormat`or`SimpleDateFormat`to look up parsing and formatting patterns. The internal API normally used is new in JDK 8 and not supported on Android. Formatting in ISO Chronology appears unaffected; non-ISO dates and times are calculated correctly but formatted (and parsed) using ISO patterns.
- `Temporal.getDisplayName(Locale)`never localizes for built-in field types and instead always returns English names such as "Day", "Week", and "Year".
- Similarly, chronology names are never localized during formatting and parsing, as this information doesn't seem to be available on legacy devices.
- Formatting and parsing are limited to most`ChronoField`constants (except quarters) and only supports ISO chronology concepts such as 7-day weeks, 12-month years, BC and AD eras, etc. For instance, Japanese eras don't work. "Standalone" formats also don't work. This is all due to the necessary localized strings not available through legacy JDK APIs.
- `JapaneseChronology`only partially supports the current REIWA era, depending on whether the Android frameworks on the device and the desugared library versions pre-date the start of the REIWA era (2019).
- `HijrahChronology`doesn't support "variants". Android 8 doesn't include any such variants, so this shouldn't make any practical difference.
- Time zone formatting ("printing") won't localize "generic" time zone names in the rare situation when the`Temporal`to print doesn't include "seconds". Generic time zone names simply aren't available on legacy devices, only "standard" and "daylight savings"-specific names.
- `ZoneRules`by default fall back on`java.util.TimeZone`. This has limitations listed below. Note that the primary method in this class,`ZoneRules.getOffset(Instant)`, should work accurately whenever data is available.
- Typically data appears to be available back to \~1900 on tested devices, so queries for 18xx (before the use of modern time zones) will probably return wrong results. Note the first daylight saving occurred in 1916, which is typically covered.
- `getStandardOffset()`doesn't work for time periods where a given timezone used a different offset from UTC. Because of that,`isDaylightSavings()`and`getDaylightSavings()`may also return wrong results in problematic time periods.
- `nextTransition()`and`previousTransition()`are slow but appear accurate within available data.
- `getTransitions()`and`getTransitionRules()`return empty lists. That's consistent with the spec but may be surprising; use`nextTransition()`or`previousTransition()`instead.
## `java.nio`customizations
Generally speaking, this is how`java.nio`desugaring works:
- When the runtime device is running Android 8.0 (API level 26) or higher, it wraps the platform`java.nio`code.
- When the runtime device is running on a platform strictly lower than API level 26, it emulates the APIs using`java.io`and`java.nio`code predating API 26.
The toolchain tries to make everything compatible, but has some limitations for API levels below 26 because some features cannot be emulated at this level. All the`java.nio`code works on devices running API level 26 or higher, so existing code guarded by an API level check should work as it used to.
The following is a list of features which aren't supported when the runtime device is strictly lower than API level 26. Calls to such APIs either return null or throw an instance of`java.lang.UnsupportedOperationException`.
- `java.nio.channels.AsynchronousFileChannel`
- Posix file features (group, owner, permissions), including reading or writing the attributes or attribute view or`FileSystem#getUserPrincipalLookupService`
- Watch service, including`FileSystem#newWatchService`or`Path#register`
The following is a summary of potentially behavior-changing modifications to other`java.nio`APIs when the runtime device is strictly lower than API level 26:
- Links and symbolic links cannot be created using`FileSystemProvider#createLink`or`FileSystemProvider#createSymbolicLink`, but APIs such as`BasicFileAttributes#isSymbolicLink`are supported.
- New`java.nio.channels.FileChannel`instantiation methods are emulated using`RandomAccessFile#getChannel`, which can be opened only with`r`,`rw`,`rws`or`rwd`. That means for example that write-only file channels are emulated with read-write file channels. The desugaring implementation tries to support the open options such as`CREATE`,`CREATE_NEW`,`TRUNCATE_EXISTING`,`DELETE_ON_CLOSE`, and`APPEND`.`SPARSE`is ignored and the open option`DELETE_ON_CLOSE`closes the file later than the JVM does it. The file is closed when FileChannel is closed.
- File operations sometimes raise`java.io.FileNotFoundException`instead of`java.nio.file.NoSuchFileException`when a file is not found. They are both subclasses of`java.io.IOException`, so the issue can be mitigated by catching`java.io.IOException`in user code.
- The`java.nio.file.attribute.FileAttribute`parameter in many APIs is ignored. The attribute usually contains a set of posix permissions.
- File copy with the`COPY_ATTRIBUTES`option does not copy attributes, though it is usually not relevant to copy basic attributes.
- File move with the`ATOMIC_MOVE`option uses file renaming. Linux does not guarantee renaming to be atomic, though it usually is, and the desugaring implementation will have the semantics of the OS.
