当顶部还有另一个活动时，不会调用onNewIntent（）

Question

Seems that onNewIntent() of my MainActivity is not being called when I have another Activity on top of it, if I close the second Activity it does get called just fine, it's like the other Activity which is on top is blocking the messages? Both Activity s are set to singleTop in the manifest and I set the Intent from a notification:

Intent intent = new Intent(getApplicationContext(), MainActivity.class);
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
PendingIntent pIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

Does anybody know what could be wrong?

Thanks!

Answer 1

You have probably already searched google - there are lots of questions on why onNewIntent is not called.

It might depend on which android version you are doing tests, but you might try adding Intent.FLAG_ACTIVITY_SINGLE_TOP flag to your intent - even though you have it in your manifest, together with Intent.FLAG_ACTIVITY_CLEAR_TOP .

intent.setFlag(Intent.FLAG_ACTIVITY_SINGLE_TOP|Intent.FLAG_ACTIVITY_CLEAR_TOP);

this will remove activities above you activity which you want to launch.

But if your intent is to keep two activities alive, and switch between them, then look into android:taskAffinity and FLAG_ACTIVITY_NEW_TASK .

Answer 2

Verify that the correct launch mode is set for the Activity receiving the Intent. Set launchMode to " singleTop " in their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag when calling startActivity(Intent) .
