Common mistakes when working with MediaPlayer?

When working with the MediaPlayer class in Android, developers often encounter several common mistakes that can lead to poor performance, crashes, or unresponsive applications. Here are some of the most prevalent pitfalls and how to avoid them.

1. Not using prepareAsync()

Using prepare() on the MediaPlayer in the main thread can lead to ANRs (Application Not Responding). Always use prepareAsync() for loading media files.

MediaPlayer mediaPlayer = new MediaPlayer(); mediaPlayer.setDataSource("your_audio_file.mp3"); mediaPlayer.prepareAsync(); // Correct usage

2. Forgetting to release resources

Failing to call release() on the MediaPlayer can lead to memory leaks. Always release it when it's no longer needed.

@Override protected void onDestroy() { super.onDestroy(); if (mediaPlayer != null) { mediaPlayer.release(); // Always release MediaPlayer mediaPlayer = null; } }

3. Not Handling Playback States

It's important to handle the various states of MediaPlayer to avoid crashes when trying to play, pause, or stop media playback in an incorrect state.

if (mediaPlayer.isPlaying()) { mediaPlayer.pause(); // Verify if playing before pausing }

4. Ignoring error handling

Always implement the OnErrorListener to gracefully handle errors during playback, such as file not found or unsupported format.

mediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() { @Override public boolean onError(MediaPlayer mp, int what, int extra) { // Handle errors return true; // Return true if you handled the error } });
