Inspector</a></strong> lets you examine snapshots of your layout hierarchy
while your app is running on the emulator or a device.
</li>

<li>New <strong><a href="/studio/write/firebase.html">Assistant</a></strong>
window to help you integrate Firebase services into your app.

</li>

<li>New <strong>C/C++ build integration with CMake and ndk-build</strong>.
Compile and build new or existing native code into libraries packaged into
your APK, and debug using lldb. For new projects, Android Studio uses CMake
by default, but also supports ndk-build for existing projects. To learn how
to include native code in your Android application, read <a href=
"/studio/projects/add-native-code.html">Add C and C++ Code to Your
Project</a>. To learn how to debug native code with lldb, see <a href=

बदलाव

  • IDE के कोडबेस को IntelliJ 15 से IntelliJ 2016.1 पर अपडेट किया गया
  • 'इंस्टैंट रन' के लिए अब टारगेट डिवाइस के एपीआई लेवल से जुड़े प्लैटफ़ॉर्म का SDK टूल इंस्टॉल करना ज़रूरी है.
  • अगर उपयोगकर्ता ऐप्लिकेशन को वर्क प्रोफ़ाइल या सेकंडरी उपयोगकर्ता के तौर पर चला रहा है, तो इंस्टैंट रन अपने-आप बंद हो जाएगा.
  • इंस्टैंट रन की विश्वसनीयता से जुड़ी कई समस्याओं को ठीक किया गया, जिनमें बदलाव लागू नहीं हो रहे थे या ऐप्लिकेशन क्रैश हो जाता था:
    • आपके मौजूदा ऐप्लिकेशन पर कुछ ऐप्लिकेशन ऐसेट डिप्लॉय नहीं की गई. ( गड़बड़ी: #213454)
    • जब उपयोगकर्ता, इंस्टैंट रन और नॉन-इंस्टैंट रन सेशन के बीच ट्रांज़िशन करता है, तो ऐप्लिकेशन क्रैश हो जाता है. ऐसा तब होता है, जब Serializable क्लास में serialVersionUID की जानकारी नहीं दी गई हो. (गड़बड़ी: #209006)
    • स्टाइल में किए गए बदलाव, Instant Run में नहीं दिखते. (गड़बड़ी: #210851)
    • इंस्टैंट रन सेशन भरोसेमंद नहीं है और इसकी वजह से FileNotFoundException होता है. (बग: #213083)
    • KitKat के लिए, ड्रॉबल में किए गए बदलाव तब तक नहीं दिखते, जब तक कि पूरी तरह से फिर से न बनाया जाए. (गड़बड़ी: #21530)
    • कस्टम sourceSets में नेस्ट किए गए पाथ होने पर, संसाधन में किए गए बदलाव, इंस्टैंट रन में नहीं दिखते. (गड़बड़ी: #219145)
    • अगर बदली गई क्लास में, सूची में शामिल वैल्यू के साथ एनोटेशन मौजूद है, तो हॉट और वॉर्म स्वैप काम नहीं करते. (बग: #209047)
    • एनोटेशन डेटा में किए गए बदलाव, Instant Run में नहीं दिखते. (गड़बड़ी: #210089)
    • अगर IDE के बाहर बदलाव किए जाते हैं, तो इंस्टैंट रन को कोड में हुए बदलाव नहीं दिखते. (बग: #213205)
    • सुरक्षा टोकन मेल न खाने की वजह से, इंस्टैंट रन सेशन भरोसेमंद नहीं है. (गड़बड़ी: #211989
    • कोल्ड स्वैप उन डिवाइसों को नहीं बदला जा सकता जो 'रन-अस' काम नहीं करते हैं. (गड़बड़ी: #210875)
    • इंस्टैंट रन रीस्टार्ट होने के बाद ऐप्लिकेशन क्रैश हो जाता है. (गड़बड़ी: #219744)
    • इंस्टैंट रन से इंस्टैंट डीबग पर स्विच करने पर, ClassNotFoundException का पता चला. (बग: #215805)
