android-pendingintent

问题 My app has notifications, which - obviously - without any flags, start a new activity every time so I get multiple same activities running on top of each other, which is just wrong. What I want it to do is to bring the activity specified in the notifications pending intent, to the front if it is already running, otherwise start it. So far, the intent/pending intent for that notification I have is private static PendingIntent prepareIntent(Context context) { Intent intent = new Intent(context,

问题 I'm having trouble working with the AlarmManager . I want to run AlarmManager using Calendar at a specific time. But the calendar doesn't work and AlarmManager always runs regardless of the time taken from the calendar. AlarmManager mAlarmManger = (AlarmManager) Objects.requireNonNull(activity).getSystemService(view.getContext().ALARM_SERVICE); Intent intent = new Intent(activity, MyReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(activity, 0, intent, PendingIntent

问题 Actually I'm trying to pass intent to an activity on click of the push-notification and it's working fine when the app is present in foreground .But when the app is in background although I'm receiving the push-notification without any problem but by clicking that notification I'm not getting intent in the activity .

问题 I want to receive an Intent instance from an Activity launched by an AlarmManager with a pendingIntent. I have the Activity A launch the Activity B through alarmManager with pendingIntent like this : PendingIntent pendingIntent = PendingIntent.getActivity(this, position, intentListAlarmActivityToWakeUpActivity, 0); Log.i("position", position +""); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.set(Calendar.HOUR_OF_DAY, hourAlarm);

问题 I'd like to start multiple activities when press on Notification. I didn't find any docs about how to set multiple intents in a single PendingIntent . One solution could be to start next activity in the first one's onCreate() and so forth, but I don't like this, maybe there is something else. 回答1: Finally, I got the answer for this - it's pretty trivial, just using method getActivities() to the PendingIntent like so: Intent myIntent1= new Intent(ctx, MyActivity1.class); myIntent1.setFlags
