Question

我有以下代码。应该以一定的间隔在logcat中发送消息但是不起作用。 stackoverflow上有很多类似的帖子，但我无法弄清楚问题。在某处可以帮助我吗？

<receiver android:name="BoopoohooAlarmReceiver"></receiver>

public void startAlarmManager(long interval){
    Context context = getApplicationContext();
    Intent intent = new Intent(context, BoopoohooAlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
    AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.add(Calendar.SECOND, 10);
    Log.i(DEBUG, "hollaa");
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), interval, pendingIntent);
}

public class BoopoohooAlarmReceiver extends BroadcastReceiver {
    private final String DEBUG = "BoopoohooAlarmReceiver"; 
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(DEBUG, "onReceive");
    }
}

感谢。

尝试添加“。” （点）在android清单文件声明中的接收者名称前面。

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

This也可能会有所帮助。
