如何在安卓设备关屏的情况下运行应用

public class MyBackgroundService extends Service {
    private PowerManager.WakeLock wakeLock;

    @Override
    public void onCreate() {
        super.onCreate();
        PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
        wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyApp::MyWakelockTag");
        wakeLock.acquire();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 在这里执行后台任务
        new Thread(new Runnable() {
            @Override
            public void run() {
                // 执行长时间运行的任务
                while (true) {
                    // 任务逻辑
                    try {
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }).start();
        return START_STICKY;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        if (wakeLock.isHeld()) {
            wakeLock.release();
        }
    }

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

<service android:name=".MyBackgroundService" />

Intent serviceIntent = new Intent(this, MyBackgroundService.class);
startService(serviceIntent);
