private Handler handler = new Handler;

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() {

@Override

public void onReceive(final Context context, Intent intent) {

int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);

int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, 100);

Log.i(TAG, "level: " + level + "; scale: " + scale);

int percent = (level*100)/scale;

final String text = String.valueOf(percent) + "%";

handler.post( new Runnable() {

public void run() {

Toast.makeText(context, text, Toast.LENGTH_SHORT).show();

}

});

}

};
