Execute a piece of code on certain Battery Level in Android

Question

I'm looking for a way of executing a piece of code within my Android application when the phone reaches 10% battery life. Would anyone be able to point me in the right direction of how to do so?

Answer 1

Write one receiver for getting the battery level like this:

public class BatteryReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);
    if (level < 10) {
        // Write your code here
    }
}

}

Write One Service:

public class BatteryService extends Service {

    private BatteryReceiver receiver;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        receiver = new BatteryReceiver();
        IntentFilter filter = new IntentFilter();
        filter.addAction(Intent.ACTION_BATTERY_CHANGED);
        registerReceiver(receiver, filter);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        unregisterReceiver(receiver);
    }
}

Register this service in your Manifest file like this:

<service android:name="com.example.testandroid.BatteryService" >
    </service>

then start the service in First Activity is Enough.
