我如何运行我的应用程序时，设备处于锁定状态和屏幕处于关闭状态？

本文介绍了我如何运行我的应用程序时，设备处于锁定状态和屏幕处于关闭状态？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用的报警服务，让应用程序运行时，我的手机被锁定，屏幕关闭，但它不能正常工作。

I am using Alarm services to keep my application running when mobile is locked and screen turned off but it does not work.

我的报警服务类是：

public class AlarmService extends BroadcastReceiver { // Restart service every 60 seconds private static final long REPEAT_TIME = 1000 * 60; @Override public void onReceive(Context context, Intent intent) { AlarmManager service = (AlarmManager) context .getSystemService(Context.ALARM_SERVICE); Intent i = new Intent(context, StartUp_broadcast.class); PendingIntent pending = PendingIntent.getBroadcast(context, 0, i, PendingIntent.FLAG_CANCEL_CURRENT); Calendar cal = Calendar.getInstance(); // Start 60 seconds after boot completed cal.add(Calendar.SECOND, 60); // // Fetch every 60 seconds // InexactRepeating allows Android to optimize the energy consumption service.setRepeating (AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), REPEAT_TIME, pending); // service.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), // REPEAT_TIME, pending); } }

和我brodcast服务类是：

and my brodcast service class is:

public class StartUp_broadcast extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Intent myIntent = new Intent(context, AlarmService.class); PendingIntent pendingIntent = PendingIntent. getService(context, 0, myIntent, 0); AlarmManager alarmManager = (AlarmManager) context .getSystemService(Context.ALARM_SERVICE); alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 1000, 1000, pendingIntent); Intent Startup_Intent = new Intent(context, LocationService.class); Startup_Intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startService(Startup_Intent); } }

我的主要活动类有PowerManager的服务为WakeLock

My main Activity class has PowerManager Service for WakeLock

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); pm = (PowerManager) getSystemService(Context.POWER_SERVICE); wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeUp"); wl.acquire(1000); //wake up the screen setContentView(R.layout.main); this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
