预定警报从不调用接收器类

我正试图设置闹钟每5分钟发射一次。

这是设置闹钟的代码:

   @Override
public void scheduleAlarmManager() {
    Timber.i("After SignIn sets AlarmManager");
    // broadcast
    Intent intent = new Intent(this, PatientAlarmReceiver.class);
    intent.setAction(PATIENT_START_ALARM_ACTION);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
            this, REQUEST_CODE, intent, 0);

    // and set alarmManager
    AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

    Calendar currentCal = Calendar.getInstance();
    long currentTIme = currentCal.getTimeInMillis();

    // if there's not an Alarm already set then set one
    if (!isAlarmSet(this)) {
        Timber.i("Alarm not set - so set one");
        alarm.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                currentTIme + TWO_MINS_DURATION, TWO_MINS_DURATION, pendingIntent);
    }

}

我可以验证我是否正确设置了警报,因为我在logcat中看到了我使用Timber登录的消息。

我的Receiver课程是:

public class PatientAlarmReceiver extends BroadcastReceiver {

public static final String TAG = "PATIENT-ALARM-RECEIVER";
public static final String PATIENT_START_ALARM_ACTION = "bp.headsup.receivers.alarm.patient";

@Override
public void onReceive(Context context, Intent intent) {
    Log.i(TAG, "Inside OnReceive Patient");
    Timber.i("Inside OnReceive Patient");

    if (intent == null || intent.getAction() == null) {
        return;
    }

    String action = intent.getAction();
    if (PATIENT_START_ALARM_ACTION.equalsIgnoreCase(action)) {
        onStartCheckForConnectionRequest(context);
    }
}

/**
 * If is connected to network starts services
 */
private void onStartCheckForConnectionRequest(Context context) {
    NetworkUtils networkUtils = new NetworkUtils(context);
    if (networkUtils.isNetworkConnected()) {
        Intent checkForConnRequestIntent = new Intent(context, PatientCheckForConnectionRequestService.class);
        context.startService(checkForConnRequestIntent);
        Timber.i("Starts Service From PatientALARMMANAGER");
    }
}

}

我在Manifest中声明:

        <!-- Receivers -->
    <receiver
        android:name="bp.headsup.receivers.PatientAlarmReceiver" />

如果我跑:adb shell dumpsys alarm 我可以看到:

  ELAPSED_WAKEUP #0: Alarm{42d804e8 type 2 bp.headsup.mock}
operation=PendingIntent{42d0c230: PendingIntentRecord{42d0f000 bp.headsup.mock broadcastIntent}}

上面的响应中的模拟是我正在使用的sourceSet - 不知道它是否与此有关,我只是提到它。

问题是我从未在logcat中读过我在Receiver类onReceive中的消息,显然没有服务启动。任何人都可以帮忙吗?我正在使用一个运行kitKat 4.4(api 19)的设备,但我也尝试使用模拟器,结果是一样的。

答案 0 :(得分:1)

您正在设置ELAPSED_REALTIME警报,该警报基于自上次启动以来的时间。但是,您根据&#34;挂钟&#34;传递它的开始时间,所以您的闹钟实际上将在未来设置得相当远。

您可以将闹钟更改为RTC类型,也可以从SystemClock.elapsedRealtime()获取开始时间。鉴于您描述的行为,保持已过时的类型并更正开始时间似乎是合适的。
