Question

应用程序Pupose ：简单的闹钟。

应用程序在Android 4.2.1（Jelly Beans）上正常运行。

应用程序完全搞砸了Android 5.1.1（Lollipop）

问题详细信息：当闹钟时间结束时，将调用“服务”。但是当我关闭闹钟时，它会在2-3秒后再次调用，然后立即延迟一段时间。无论我多少次关闭闹钟..活动关闭并一次又一次地重新出现（必须从最近的应用程序中刷出应用程序）。

另一个问题是，服务理念是确保......无论用户是否关闭应用程序，警报都会响铃......这在Android 4.2.1上是正常的，但是如果我关闭应用程序那么报警也是如此（服务）。

另一个问题：如果设置闹钟并关闭应用广播接收器，则不会被呼叫。当时没有采取任何行动。

尚未检查其他版本......

我正在使用AlarmManager使用以下代码设置闹钟定时器。函数从活动中调用。

 public static void setAlarm(Context context, int pendingIntentCode, long timeToAlarm, int alarmMode, String alarmTitle) {
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

    Intent intent = new Intent(context, AlarmReceiver.class);
    Log.d(TAG, "Pending Intent Code" + pendingIntentCode);
    intent.putExtra("pendingIntentCode", pendingIntentCode);
    intent.putExtra("alarmMode", alarmMode);
    intent.putExtra("alarmTitle", alarmTitle);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, pendingIntentCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    if (SDK_INT < Build.VERSION_CODES.KITKAT) {
        alarmManager.set(AlarmManager.RTC_WAKEUP, timeToAlarm, pendingIntent);
    } else if (Build.VERSION_CODES.KITKAT <= SDK_INT && SDK_INT < Build.VERSION_CODES.M) {
        alarmManager.setExact(AlarmManager.RTC_WAKEUP, timeToAlarm, pendingIntent);
    } else if (SDK_INT >= Build.VERSION_CODES.M) {
        alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, timeToAlarm, pendingIntent);
    }


}

BroadCast接收器代码。

 @Override
public void onReceive(Context context, Intent intent) {

    int pendingIntentCode = intent.getIntExtra("pendingIntentCode", 0);
    int mode = intent.getIntExtra("alarmMode", 0);
    String alarmTitle = intent.getStringExtra("alarmTitle");

    Intent startServiceIntent = new Intent(context, AlarmByService.class);
    startServiceIntent.putExtra("alarmTitle", alarmTitle);
    startServiceIntent.putExtra("alarmMode", mode);
    startServiceIntent.putExtra("pendingIntentCode", pendingIntentCode);

    context.startService(startServiceIntent);

    Log.d(TAG, "on Receive");

}

在服务类中，剩余的功能是相同的...除了调用MediaPlayer.stop的ondestroy。

 @Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);
    sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
    editor = sharedPreferences.edit();

    int annoyingMethod = sharedPreferences.getInt("annoyingMethod", 0);
    String calmModeTone = sharedPreferences.getString("alarm_tone_calm_mode", "default");
    String annoyingModeTone = sharedPreferences.getString("alarm_tone_annoying_mode", "default");
    vibration = sharedPreferences.getInt("vibration", 0);
    int mode = intent.getIntExtra("alarmMode", 0);
    int pendingIntentCode = intent.getIntExtra("pendingIntentCode", 0);
    String alarmTitle = intent.getStringExtra("alarmTitle");

    Intent activityToCall = null;


    if (mode == 0) {
        activityToCall = new Intent(AlarmByService.this, CalmModeAlarmDisplay.class);
        activityToCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        activityToCall.putExtra("pendingIntentCode", pendingIntentCode);
        activityToCall.putExtra("alarmTitle", alarmTitle);

        MediaPlayerForAlarm.playAlarm(calmModeTone, this, vibration);

    } else {
        MediaPlayerForAlarm.playAlarm(annoyingModeTone, this, 1);
        switch (annoyingMethod) {
            case 0:
                activityToCall = new Intent(AlarmByService.this, DrawPattern.class);
                activityToCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                activityToCall.putExtra("pendingIntentCode", pendingIntentCode);
                activityToCall.putExtra("alarmTitle", alarmTitle);
                break;
            case 1:
                activityToCall = new Intent(AlarmByService.this, SolveMathProblem.class);
                activityToCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                activityToCall.putExtra("pendingIntentCode", pendingIntentCode);
                activityToCall.putExtra("alarmTitle", alarmTitle);
                break;
            case 2:
                activityToCall = new Intent(AlarmByService.this, ShakeDevice.class);
                activityToCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                activityToCall.putExtra("pendingIntentCode", pendingIntentCode);
                activityToCall.putExtra("alarmTitle", alarmTitle);
                break;
        }
    }


    if (activityToCall != null) {
        Log.d(TAG, "Calling Activity Intent is not Null");
        startActivity(activityToCall);

    }
    if (alarmTitle == null || pendingIntentCode == 0) {
        Log.d(TAG, "Stopping Service Unintentional Call");
        stopSelf();

    }

    Log.d(TAG, "Title " + alarmTitle);
    Log.d(TAG, "Vibration: " + vibration);


    PendingIntent pendingIntent = PendingIntent.getActivity(AlarmByService.this, 0, activityToCall, 0);

    Notification alarmNotification = new NotificationCompat.Builder(AlarmByService.this)
            .setSmallIcon(R.drawable.app_icon)
            .setContentTitle(alarmTitle)
            .setContentText("Tap here to see Alarm Detail.")
            .setContentIntent(pendingIntent).build();

    startForeground(1337, alarmNotification);


    return START_NOT_STICKY;
}

过去两天我用Google搜索了这么多时间......并且找不到任何东西......可能是我不擅长谷歌搜索......任何帮助都是WellCome ......

如果提供的信息不足，我可以提供更多......

先谢谢。

首次执行onReceive函数后，WakefulBroadcastReceiver将不停止触发
