Android鬧鐘管理器：OnRecive和PendingIntent服務不會被調用

Question

我嘗試使用鬧鐘管理器在8:30發送意圖，但鬧鐘管理員從未在8:30左右將意圖發送給接收方。

我在setAlarm（）方法中搞砸了一些東西，但我找不出來。 此處的許多帖子也提到服務/接收者可能在清單文件中聲明爲錯誤，但我不確定如何在清單中正確包含接收者和服務。我試圖加入軟件包名稱，但它仍然不起作用。

public class EventAlarmReceiver extends WakefulBroadcastReceiver { 
private AlarmManager alarmMgr; 
private PendingIntent alarmIntent; 
private PendingIntent alarmIntent1; 

@Override 
public void onReceive(Context context, Intent intent) { 
    Intent service = new Intent(context, EventSchedulingService.class); 
    startWakefulService(context, service); 
} 

public void setAlarm(Context context) { 
     alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
     Intent intent = new Intent(context, EventSchedulingService.class); 
     intent.putExtra("silent", true); 
     alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0); 

     Calendar calendar = Calendar.getInstance(); 
     calendar.setTimeInMillis(System.currentTimeMillis()); 
     // Set the alarm's trigger time to 8:30 a.m. 
     calendar.set(Calendar.HOUR_OF_DAY,8); 
     calendar.set(Calendar.MINUTE, 30); 
     System.out.println(calendar.getTimeInMillis()); 
     alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent); 
} 
} 

這裏是我的服務文件

package edu.ssui.smartsilent; 

public class EventSchedulingService extends IntentService { 

public EventSchedulingService() { 
    super("EventSchedulingService"); 
} 
@Override 
protected void onHandleIntent(Intent intent) { 
    Log.d("SService", "m1"); 
    AudioManager mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE); 
    if(intent.getExtras().getBoolean("silent")==true){ 
    mgr.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
    mgr.setStreamVolume(AudioManager.STREAM_ALARM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
    mgr.setStreamVolume(AudioManager.STREAM_SYSTEM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
    mgr.setStreamVolume(AudioManager.STREAM_NOTIFICATION, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
    } 
    else 
    { 
     mgr.setStreamVolume(AudioManager.STREAM_RING, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_RING)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
     mgr.setStreamVolume(AudioManager.STREAM_ALARM, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_ALARM)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
     mgr.setStreamVolume(AudioManager.STREAM_SYSTEM, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_SYSTEM)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
     mgr.setStreamVolume(AudioManager.STREAM_NOTIFICATION, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_NOTIFICATION)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE); 
    } 
    Log.d("SService", "m1"); 
    EventAlarmReceiver.completeWakefulIntent(intent); 

} 

}

Answer 1

要調用：

alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0); 

PendingIntent.getBroadcast（背景下，意圖）將檢索將與上下文進行廣播一個的PendingIntent和意圖你通過了。例如，它會調用Context.sendBroadcast（意圖），它將意向發送給所有感興趣的BroadcastReceivers。

而不是做的：

Intent intent = new Intent(context, EventSchedulingService.class); 

嘗試通過一個BroadcastReceiver的意圖構造。

Answer 2

試試這個：

 alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
     Intent intent = new Intent(context, EventAlarmReceiver.class); 
     intent.putExtra("silent", true); 
     alarmIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

     Calendar calendar = Calendar.getInstance(); 
//  calendar.setTimeInMillis(System.currentTimeMillis()); 
     // Set the alarm's trigger time to 8:30 a.m. 
     calendar.set(Calendar.HOUR_OF_DAY,8); 
     calendar.set(Calendar.MINUTE, 30); 
     System.out.println(calendar.getTimeInMillis()); 
     alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent); 

也把日誌進行調試，並確保你調用setAlarm（）。

Answer 3

這個權限添加到您的menifest：

<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
