Android Question Accessing files of another apk

[HARRY]

Hi,

I have two apk's, which are related to each other. One creates a file to be used by the second one. Does any possibility exist with Android 4.4.2 to realize that the second apk deletes and creates a file in the Files folder of the first apk? May be by special permissions?

1. The assets folder (Files tab in the IDE) is read-only. You cannot write to it.
2. You can access files in the secondary storage (File.DirRootExternal or File.DirDefaultExternal).

You can copy the file from the folder DirAssets, to the root (or anywhere) and so you can access from the two applications.

Also if you know the destination folder, you can copy it from the folder DirAssets.

File.copy(File.DirAssets,"FileName",File.DirRootExternal, "/Filename")
File.copy(File.DirAssets,"FileName",File.DirRootExternal, "/Android/data/packageName/files/FileName")

regards

No result. I tried with File.DirRootExternal , but it refers to the Phone storage itself, not to the SDcard. Then I tried to refer to the SDCard, as named on my mobile: "/storage/extSdCard", but then I get access denied. More suggestions?
By the way, I use Android 4.42.

For a long time, and "security policy" on Google , you can not write to the external SD program, unless you're root.

Look at this:

On Android 4.4+ you can find the path to the sd card with the code posted here: https://www.b4x.com/android/forum/threads/how-to-ext-sd-card-write-on-android-4-4.42177/#post-255351

You can also use RuntimePermissions.GetAllSafeDirsExternal to find the sd card path.
