java - 广播接收器未接收到广播

Question

我似乎无法让我的 onReceive 类接收我发出的任何广播。我不确定是我的代码有问题还是 Android list 有问题。

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i("BROADCAST_RECEIVED", intent.getDataString());
        PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP, "");
        wakeLock.acquire();
        wakeLock.release();
        context.startActivity(intent);
    }

}

public void setDayOfWeekAlarm(DayOfWeek day){
    long alarmInMili = 0;
    Intent intent = new Intent(context,AlarmScreenActivity.class);
    alarmInMili = System.currentTimeMillis() + 1000*10;
    Log.i("REGISTER ALARM", String.valueOf(alarmInMili));
    AlarmManager alarmManager = (AlarmManager)  context.getSystemService(Context.ALARM_SERVICE);
    PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
    alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,SystemClock.elapsedRealtime() +
            10 * 1000,pi);
}

除了 Gabe 的回答之外，您在 setDayOfWeekAlarm() 中使用的 Intent 也指向 AlarmScreenActivity。这不是您的 BroadcastReceiver，也不是您 list 中注册的任何其他组件。
