Can two AGK2 apps running on the same Android system get to each other's files and directories?

If you have a server, you could create a shared folder for your apps to dip into.

Thanks guys! Both good ideas. One thing you learn from programming is that there are almost always work arounds to situations you encounter.

Perhaps have them communicate through a data file (text)?

There are many ways I can think of to allow AppGameKit apps to share data, but that's not what the question was?

The problem of accessing files outside the sandboxed area allowed to your app is not a limitation of AppGameKit, it's how Android works.

I know that Android was designed, much like iOS using a "sandbox" model for security reasons. But then how do so many of the other apps on Android allow me to edit my photos, text files, etc.?

I have a lot of apps on my phone that allow me to browse the file structure on Android. Granted, it does not allow me full access, i.e. other files executables and graphics, but I can see a lot of what other apps put on my phone, tablet, etc.

Some graphics editors even show me the graphics for my AGK2 apps and allow me full access to delete and edit them.

This was an attempt to somewhat do a work around for the limitation of the "sandbox". What I really wanted to do was grab files like photos taken with my phone/tablet and work on them. But I thought that just maybe, since the file structure on my Windows system shows that all of the AGK2 app directories are in a common AGK2 directory that at least I could share files between two AGK2 apps, like a simple .txt file. I did some testing and I now don't think that's even it's possible.

I ran this code to no avail:

		Inc countF
		fnF$=GetNextFolder()

	Print ("Total Folder Count:"+Str(countF,0))

endwhile

end

And I put a graphic in the "media" directory to see if I could find it and I did, in the first section. Then when I used setfolder("") it jumped to another directory with AppGameKit assets in it.
but I could not go further toward the root directory.

If your goal is to play with images in your gallery, it might be worth looking at:
* ShowChooseImageScreen
* IsChoosingImage
* GetChosenImage

Since we can make an image from a memblock, and make a memblock from an image...

Two different apps could have access to the same image file perhaps?

A kludgy work-around, I know, but it might be a way to pass data.
