无法在 Android 上使用 AlarmManager 安排通知(使用 Qt)
Unable to schedule notification with AlarmManager on Android (using Qt)
我正在从 qt 5.5 执行以下操作。项目。
我正在尝试使用 android 中的警报管理器安排本地通知。这是安排通知的代码:
class ScheduledNotifications {
static public int notification_id = 0;
static int scheduleNotification(String title, String content, int futureInMilliseconds) {
++notification_id;
Intent notificationIntent = new Intent(QtNative.activity(), NotificationPublisher.class);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID, notification_id);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, createNotification(title,content));
PendingIntent pendingIntent = PendingIntent.getBroadcast(QtNative.activity(), 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager)QtNative.activity().getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, /*futureInMilliseconds*/0, pendingIntent);
Log.d("!" ,"Scheduled");
return notification_id;
}
static public Notification createNotification(String title, String content) {
Notification.Builder builder = new Notification.Builder(QtNative.activity());
builder.setContentTitle(title);
builder.setContentText(content);
return builder.build();
}
}
这是 NotificationPublisher,它应该显示通知:
class NotificationPublisher extends BroadcastReceiver {
public static String NOTIFICATION_ID = "notification-id";
public static String NOTIFICATION = "notification";
public void onReceive(Context context, Intent intent) {//Called when its time to show the notification ...
Log.d("!", "Notified");
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = intent.getParcelableExtra(NOTIFICATION);
int id = intent.getIntExtra(NOTIFICATION_ID, 0);
notificationManager.notify(id, notification);
}
}
对于调试程序,我将 "wakeup" 时间设置为 0(因此通知应立即出现)。
Lod.d("!","Scheduled")
输出出现在控制台输出中,但 Log.d("!", "Notified")
没有。那么我是否以某种方式安排了警报?
老实说,不能 100% 确定为什么你的不工作,但我怀疑是传入的 0。我认为这应该是 System.currentTimeInMillis() + SOME_SHORT_INTERVAL ?
这是警报管理器设置的一个工作示例。是的,我知道它的不同,但它是值得比较的
Intent syncIntent = new Intent(this, SyncIntentService.class);
syncIntent.putExtra(EXTRA_REQUEST_KEY,
SyncRequestTypes.REQUEST_BACKGROUND_SYNC.name());
PendingIntent pi = PendingIntent.getService(this, 0, syncIntent,
Intent.FLAG_ACTIVITY_NO_USER_ACTION);
// Register first run and then interval for repeated cycles.
alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() + DEFAULT_INITIAL_RUN_TEST,
DEFAULT_RUN_INTERVAL_TEST, pi);
我在 AndroidManifest.xml 中出错了。 NotificationPublisher 需要注册为接收者,像这样:
<receiver android:name="de.goodpoint_heidelberg.NotificationPublisher" android:enabled="true"/>
