Question

我有一个代码设置一个新的重复警报（在生产中我将使用不精确的重复），但是我已经注册处理它的BroadCastReceiver没有被调用。

以下是我设置闹钟的代码：

newAlarmPeriod = 5000; // For debugging

Intent alarmIntent = new Intent(this, GroupsCheckAlarmReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(this, Constants.CHECK_ALARM_CODE,
                                                  alarmIntent, 0);

AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() 
                + newAlarmPeriod, newAlarmPeriod, sender);

它似乎工作，它每五秒钟触发并发出警报，如“adb shell dumpsys alarm”输出中所示：

DUMP OF SERVICE alarm:
Current Alarm Manager state:

  Realtime wakeup (now=1269941046923):
  RTC_WAKEUP #1: Alarm{43cbac58 type 0 android}
    type=0 when=1269997200000 repeatInterval=0 count=0
    operation=PendingIntent{43bb1738: PendingIntentRecord{43bb1248 android broadcastIntent}}
  RTC_WAKEUP #0: Alarm{43ce30e0 type 0 com.almarsoft.GroundhogReader}
    type=0 when=1269941049555 repeatInterval=5000 count=1
    operation=PendingIntent{43d990c8: PendingIntentRecord{43d49108 com.almarsoft.GroundhogReader broadcastIntent}}
  RTC #1: Alarm{43bfc250 type 1 android}
    type=1 when=1269993600000 repeatInterval=0 count=0
    operation=PendingIntent{43c5a618: PendingIntentRecord{43c4f048 android broadcastIntent}}
  RTC #0: Alarm{43d67dd8 type 1 android}
    type=1 when=1269941100000 repeatInterval=0 count=0
    operation=PendingIntent{43c4e0f0: PendingIntentRecord{43c4f6c8 android broadcastIntent}}

  Broadcast ref count: 0

  Alarm Stats:
  android
    24390ms running, 0 wakeups
    80 alarms: act=android.intent.action.TIME_TICK flg=0x40000004
  com.almarsoft.GroundhogReader
    26ms running, 2 wakeups
    2 alarms: flg=0x4 cmp=com.almarsoft.GroundhogReader/.GroupsCheckAlarmReceiver

但由于某些原因，触发警报时未调用BroadCastReceiver。我在Manifest上声明了它：

<receiver android:name=".GroupsCheckAlarmReceiver" />

这是缩写代码：

public class GroupsCheckAlarmReceiver extends BroadcastReceiver{
  @Override
  public void onReceive(Context context, Intent intent) {
     Toast.makeText(context, "XXX Alarm worked.", Toast.LENGTH_LONG).show();
     Log.d("XXX", "GroupsCheckAlarmReceiver.onReceive");
  }

Answer 1

我发现了问题，这是一个非常愚蠢的错误。 <receiver>标记位于<manifest>内，但位于<application>标记之外。谢谢你的时间，伙计们。

Answer 2

您是否尝试将manifest receiver标志上的'enabled'属性明确设置为true？如果没有指定默认值，我在文档中找不到任何东西。

BroadcastReceiver没有收到警报的广播
