If you dont want to use the broadcast on your activity, you can use in a service!!

Example:

public class batteryChangeService extends Service {

    private BroadcastReceiver mBatteryStateReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

            if (intent.getAction().equals(Intent.ACTION_POWER_CONNECTED)) {
                Toast.makeText(context, "The device is charging", Toast.LENGTH_SHORT).show();

            } else {
                intent.getAction().equals(Intent.ACTION_POWER_DISCONNECTED);
                Toast.makeText(context, "The device is not charging", Toast.LENGTH_SHORT).show();
            }
        }
    };


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

    @Override
    public void onCreate() {
        super.onCreate();

        IntentFilter ifilter = new IntentFilter();
        ifilter.addAction(Intent.ACTION_POWER_CONNECTED);
        ifilter.addAction(Intent.ACTION_POWER_DISCONNECTED);
        registerReceiver(mBatteryStateReceiver, ifilter);
    }


    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i("LocalService", "Received start id " + startId + ": " + intent);

        return START_NOT_STICKY;
    }

    @Override
    public void onDestroy() {
        unregisterReceiver(mBatteryStateReceiver);
    }


}

Register the service in your manifest:

<service
            android:enabled="true"
            android:name="NAME.COMPANY.APPLICATION.batteryChangeService"
            android:exported="true"/>

In fact, you can use any BroadcastReceiver inside a service!
