在UncaughtExceptionHandler中通过AlarmManager设置时不调用BroadcastReceiver

Question

我使用Intent和BroadcastReceiver在未捕获的异常期间为PendingIntent设置了AlarmManager，如下面的代码所示。在我的Android 7.0设备上，此代码正常运行。在早期的设备上，永远不会调用BroadcastReceiver。为什么不呢？

我的Thread.UncaughtExceptionHandler，Application子类的成员：

public void handleUncaughtException (Thread thread, Throwable e)
{
  Intent restartIntent = new Intent (getApplicationContext (), RestartReceiver.class);

  PendingIntent pendingIntent =
    PendingIntent.getBroadcast (getApplicationContext (), 0, restartIntent, 0);

  AlarmManager alarm = (AlarmManager)getSystemService (Context.ALARM_SERVICE);
  alarm.set (AlarmManager.RTC, System.currentTimeMillis () + 5000, pendingIntent);

  System.exit (1);
}

接收者：

public class RestartReceiver extends BroadcastReceiver
{
  @Override
  public void onReceive (Context context, Intent intent)
  {
    Intent restartIntent = new Intent (context, RestartActivity.class);
    context.startActivity (restartIntent);
  }
}
