Hello.
I use an app A to open an app B made in AI
my problem is A can open several time B.
today it open several instances of B (B play music, so i have twice or more musics played)
So I don't want to open new instance of B but the one which is already open.
How can i prevent B to open twice ?
I took a whack at this problem, but failed.
I thought TinyDB changes in one instance of the app might be visible in another instance of the app at startup time. Sample code:
This experiment failed.
On second thought, perhaps changing the Namespace of TinyDB on the fly might flush TinyDB from RAM to the file system, where it will be available to a fresh copy of the app.
It's a good idea ABG !
may be using a file instead of TinyDB...
A file is probably the classical way to do it.
Here is another attempt that failed ...
I must admit I rarely interact with the Android O/S as a user, preferring to spend my time with program and data structures.
I see you have as far as failed tries as I 
yo might want to modify the manifest of B

How do you open app B from A, with Activy Starter?
In this case app B can tell app A that it is already open and working.
I open app B from a service
I can modify manifest of an AI app ?
well, I don't know if you can, but if you want to know how to modify the manifest, then a search in the community might help...
