How to make Broadcast receivers backward compatible?

Broadcast receivers are an essential component of Android applications that allow you to respond to broadcast messages from other applications or the system itself. To ensure your broadcast receivers are backward compatible, you can follow certain best practices that accommodate older versions of the Android operating system.

Best Practices for Backward Compatibility

  • Use Explicit Intents for Local Broadcasts: When dealing with your own application components, explicit intents are safer and help avoid conflicts.
  • Check Android Version: Use runtime checks to implement different behaviors based on the Android version.
  • Register Receivers in Manifest: For backward compatibility, register your receivers in the AndroidManifest.xml file to ensure they are triggered by system broadcasts even when the application is not running.
  • Utilize Support Libraries: Use AndroidX libraries to access backward-compatible features.

Example Code

<receiver android:name=".MyBroadcastReceiver"> <intent-filter> <action android:name="com.example.broadcast.MY_NOTIFICATION"/> </intent-filter> </receiver>
