Android - open or restart app after clicking push notification using flag activities
提问by DijkeMark
I am using push notifications in Android. When I receive a push notification, I want to open the application if it is still running, else it should open a new instance of it.
我在 Android 中使用推送通知。当我收到推送通知时，如果应用程序仍在运行，我想打开它，否则它应该打开它的一个新实例。
I am using
我在用
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent,
Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP |
Intent.FLAG_ACTIVITY_NEW_TASK);
But when I receive a push notification now and I click on it, nothing happens.
但是，当我现在收到推送通知并单击它时，没有任何反应。
How can I still achieve this by using flagIntents?
我怎样才能通过使用 flagIntents 来实现这一点？

You need to set the Intent flags on the Intent. You were specifying them in the call to get a PendingIntent. Try this:
您需要在Intent. 您在调用中指定它们以获取PendingIntent. 试试这个：
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP |
Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);

In my case a running application restarted every time I clicked a push notification. But I don't want to restart the application.
就我而言，每次单击推送通知时，正在运行的应用程序都会重新启动。但我不想重新启动应用程序。
In PendingIntentI have an intent for needed Activity1 that called Activity2. A bug was in these lines:
在PendingIntent我有一个名为 Activity2 的所需 Activity1 的意图。这些行中有一个错误：
val intent = Intent(context, Activity2::class.java)
// Remove this line:
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK)
context.startActivity(intent)
