How to communicate between 2 mobile Apps

I’m figuring how to communicate 2 mobile Apps in the same terminal. One is UE4 App and the other not ( last one launches the Ue4 App). Both requires share some info, text files right now.

My first attempt was to find a way to share that folder path for both Apps. So they can read/write there.

Those or other ideaslike here but impletable with Ue4 are so welcome.

I’ve thought to use TCP messaging but not sure if that would be a good solution. Probably I would have to deal with SO permisions blocking messages like this TCP/UDP pluggin says: “You have to keep in mind that IOS blocks unsafe connections. It can be somehow deactivated.

I’ve posted this question to the people of mobile Utils plugin too.
