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

window to help you integrate Firebase services into your app.

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=

Location</strong> and checking the <strong>Use embedded JDK</strong>
checkbox.

- Perubahan pada drawable tidak diterapkan hingga proses build ulang penuh dilakukan untuk KitKat. (Bug: #21530)
- Perubahan resource tidak diterapkan dengan Instant Run jika sourceSets kustom berisi jalur yang disusun bertingkat. (Bug: #219145)
- Hot swap dan warm swap tidak berfungsi jika class yang diubah berisi anotasi dengan nilai enum. (Bug: #209047)
- Perubahan data anotasi tidak diterapkan dengan Instant Run. (Bug: #210089)
- Instant Run tidak menerima perubahan kode jika Anda membuat perubahan di luar IDE. (Bug: #213205)
