Мне показалось, что я понял это, но после некоторой отладки по этому вопросу: Как сделать уведомление несократимым/неустранимым Я только понял, что моя деятельность все еще продолжается. ) и onDestroyed() в случайном порядке.
Мой манифест для активности:
<activity
android:name="***.***.***.*****"
android:configChanges="orientation|keyboardHidden"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:launchMode="singleTop" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Я также пробовал launchmodes singleTask, singleInstance.
Мой код намерения для уведомления:
Intent intent = new Intent(context, MyClass.class);
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
//intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
//intent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
//intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
//intent.setFlags(Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY);
//intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
Как вы можете видеть, я пробовал каждый флаг, который, казалось бы, был бы уместным, но не повезло...
Это дает некоторые нежелательные артефакты, такие как перезапуск моего AlarmManager и запуск задачи запуска alarmmanager при каждом нажатии на уведомление. Я бы хотел этого избежать.
Любые предложения?
Изменить: я знаю, что есть масса вопросов, подобных этому, но ни одно из предлагаемых решений не похоже на трюк здесь...:/

Как уже упоминалось в комментариях, после запуска loginActivity, onResume() здесь снова вызывает вызов. То же самое после запуска alarmManager.
Кроме того, каждый раз, когда сигнализатор AlarmManager гаснет, он, кажется, выводит приложение на передний план. Любой способ избежать этого?
