@Ibrahim_Jamar my app is game mod for that reason I want the Android/data permission
I can’t be able to compile the @Taifun cod into the Extension so how I try it.
For what exactly?
If it’s a game then why are you opening folder inside Android/data permission?
Are you coping something from these folders?
I copy form “Download” Folder to Android/data to Execute the Mode file.
Wait a minute 
If it’s a game app what about copying it manually using file manager, is the game app copy these file itself? But how? I ever see kind of game doing file manager work inside the app
Can I see your app please, if it’s possible PM me
Users Never Want to Do Extra Things Like Download Other app then setup then copy manually then why they use my apk they copy and gone.
You need to get some knowledge about A Game apk and a File Manger both are different work culture and Rules.
@Ibrahim_Jamar FYI: the app, @thekarmakumar is trying to create is to help people cheating while playing a game, so the idea is to modify files in the ASD of that game app to get more lifes, to get more coins etc.
I think because of people trying things like this it was a good idea from Google to introduce scoped storage and stop these attempts…

@Taifun Thanks for explaining, but honestly I’m a bit confused here. I don’t really see how something like that can be made with Kodular. From what I understand, Android’s scoped storage blocks apps from touching another app’s private files (ASD), and Kodular doesn’t really give a way to bypass that. Maybe I’m missing something, but I thought Kodular only lets us work with our own app files or shared media (like images, audio, docs), not go inside other apps’ storage. That’s why I don’t get how it would be possible to do what @thekarmakumar describing.
In short, my question is that, it’s possible in Kodular creating a such app as of now? Because @thekarmakumar need the truth, as you can see he even dropped the price of the extension but none of us here respond to do it

Your code won’t work on Android 12 and above. There is a workaround for Android 12 but it was patched in Android 13.

What about to corporate?
I wrote a code that works on versions 11 to 14. I just want to see if the Taifun code works or not, but my code works perfectly in 11 to 14, but twist is not in 15.
