I have build an audioplayer which is deployed in android google playstore. I'm using crashlytics to monitor crashes and ANRs. Recently I have been getting a lot of crashes MediaButtonReceiver. The headset clicks work fine in many devices. But some devices are giving this problem.
Crashlytics report -

MediaSession code -

updateMetaData();

}
if (action == KeyEvent.KEYCODE_MEDIA_PLAY) {
resumeMedia();
}
}
}
return true;
}
return true;
}
});
}
What could be the problem and how to solve this?
My thoughts - Maybe this happens because user opens other music apps that has this feature while my app is still playing.

This usually occurs when your Wi-Fi or cellular data is slow or unstable, causing apps to malfunction. Another reason for Android apps crashing can be a lack of storage space in your device. This can occur when you overload your device's internal memory with heavy apps.
Select an app. On the left menu, select Quality > Android vitals > Crashes and ANRs. Near the center of your screen, use the filters to help you find and diagnose issues. Alternatively, select a cluster to get more details about a specific crash or ANR error.
You have to create your own media button receiver class, say MyMediaButtonReceiver.java, that extends MediaButtonReceiver, and it will be empty except for the onReceive method that you have to override, calling super.onReceive(...) between a try-catch that captures the IllegalStateException:
public class MyMediaButtonReceiver extends MediaButtonReceiver {
@Override
public void onReceive(Context context, Intent intent) {
try {
super.onReceive(context, intent);
} catch (IllegalStateException e) {
Log.d(this.getClass().getName(), e.getMessage());
}
}
}
Then you have to declare that receiver class in your Manifest (or replace your previous MediaButtonReceiver class declaration, if you had one), like:
<receiver android:name=".MyMediaButtonReceiver" >
<intent-filter>
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</receiver>
