我希望我的服务和广播接收器运行即使应用程序已从应用程序列表中清除或被迫停止

Question

我希望我的服务和广播接收器在后台运行即使应用已关闭或强制停止。

我的接收器正在检测屏幕响应并执行任务。当应用程序打开时以及应用程序在应用程序列表中但未关闭时，它工作正常。当我从应用程序列表中清除该应用程序时，它没有检测到屏幕响应。我尝试了很多方法，但都没有成功。帮帮我。

清单文件：-

<receiver
        android:name=".broadcastReceiver.MyReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.SCREEN_OFF"/>
            <action android:name="android.intent.action.SCREEN_ON"/>
        </intent-filter>
    </receiver>

    <service
        android:name=".service.MyService"
        android:enabled="true"
        android:exported="true"
        android:stopWithTask="false">

    </service>

我的服务class:-

private var myReceiver:MyReceiver?=null

private var defaultUEH:Thread.UncaughtExceptionHandler?=null
private var uncaughtExceptionHandler = object:Thread.UncaughtExceptionHandler{

    override fun uncaughtException(thread: Thread?, ex: Throwable?) {

        Log.d("Exception found","Uncaught exception start!")
        ex!!.printStackTrace()

        unregisterReceiver(myReceiver)

        var intent = Intent(applicationContext, MyService::class.java)
        intent.setPackage(packageName)
        var pendingIntent = PendingIntent.getService(applicationContext,1,intent,PendingIntent.FLAG_ONE_SHOT)
        var alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
        alarmManager.set(AlarmManager.ELAPSED_REALTIME,SystemClock.elapsedRealtime()+1000,pendingIntent)
        System.exit(2)

    }

}

override fun onBind(intent: Intent): IBinder? {
   return null
}

override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {

    var intentFilter = IntentFilter("android.intent.action.SCREEN_OFF")
    intentFilter.addAction("android.intent.action.SCREEN_ON")

    myReceiver = MyReceiver()
    registerReceiver(myReceiver , intentFilter)

    return START_STICKY
}

override fun onCreate() {
    super.onCreate()
    Log.d("Service" , "onCreate fun")
}

override fun onDestroy() {

    super.onDestroy()

    Log.d("Service" , "onDestroy fun")
}

override fun onTaskRemoved(rootIntent: Intent?) {

    unregisterReceiver(myReceiver)

    var intent = Intent(applicationContext, MyService::class.java)
    intent.setPackage(packageName)
    var pendingIntent = PendingIntent.getService(this,1,intent,PendingIntent.FLAG_ONE_SHOT)
    var alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
    alarmManager.set(AlarmManager.ELAPSED_REALTIME,SystemClock.elapsedRealtime()+1000,pendingIntent)
    super.onTaskRemoved(rootIntent)

}

MyReceiver class:-

override fun onReceive(context: Context?, intent: Intent?) {

    Log.d("Where ","Broadcast")
    if (intent!!.action.equals(Intent.ACTION_SCREEN_ON)){

        var dashboardActivity = DashboardActivity.instance
        var isSosEnabled = dashboardActivity!!.getSos()

        if (isSosEnabled){
            Log.d("Service Sos Enabled","True")
        }else{
            Log.d("Service Sos Enabled", "False")
        }
    }

}

您可以使用服务在主应用程序中 start/stop 服务

Intent service = new Intent(context, MyService.class);
context.startService(service);
...
Intent service = new Intent(context, MyService.class);
context.stopService(service);

服务

public class MyService extends Service
{
 private static BroadcastReceiver m_ScreenOffReceiver;

 @Override
 public IBinder onBind(Intent arg0)
 {
  return null;
 }

 @Override
 public void onCreate()
 {
  registerScreenOffReceiver();
 }

 @Override
 public void onDestroy()
 {
  unregisterReceiver(m_ScreenOffReceiver);
  m_ScreenOffReceiver = null;
 }

 private void registerScreenOffReceiver()
 {
  m_ScreenOffReceiver = new BroadcastReceiver()
  {
   @Override
   public void onReceive(Context context, Intent intent)
   {
     Log.d(TAG, "ACTION_SCREEN_OFF");
     // do something, e.g. send Intent to main app
   }
  };
  IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
  registerReceiver(m_ScreenOffReceiver, filter);
 }
}
