Receiving text opens inside another app on some devices

[marekhalmo]

Consider an application which stores your copy text stack.
The app would receive share text intent and add it to the app's list.

User would go to app A (let's say a browser).. select text, share it to this app (B). Text would be added to the list inside of app (B)

On some devices -> my app (B) opens inside the app (A) - insade task of A

What i want it to do is to push the data to an already running instance of app (B).

I tried to put singleTop, singleInstance e.t.c. to AndroidManifest but no luck.

It works on Android Emulator for Pixel3a (Android 14), and my Android 8 tablet,
but does not work on all other real android devices that i own < Android 13, 10, 11

Any idea why?

Application i start it with is always chrome - address bar

New information

It seems like where it goes OK, it comes from ReceiveSharingIntent.getTextStream() listener - when the app was already opened before, or ReceiveSharingIntent.getTextStream() if it was not opened

If my app (B) opens inside of (A) - the event commes from ReceiveSharingIntent.getTextStream() future - every time

Looks like the problem is that when it works -> the intent is started with "startActivity" vs if it does not it is launched with "startActivityWithResult"
