How to make Handler backward compatible?

To make a Handler backward compatible in Android, you can utilize the <android.os.Handler> class in combination with the <android.os.Looper> class. This allows you to work with the main thread or any other thread in a consistent way across different Android versions.

You can create a custom handler that checks the Android version and executes the appropriate method for sending messages or posting runnable tasks.

Example Implementation

public class MyHandler extends Handler { public MyHandler(Looper looper) { super(looper); } public void postDelayed(Runnable runnable, long delayMillis) { // Implement backward-compatible behavior here if necessary super.postDelayed(runnable, delayMillis); } }
