I did it like the image, but no authority was requested. I tested it with a companion.

Some permissions, like android.permission.INTERNET, are automatically granted when you installed an app (you have never seen Google asking you for internet access permission). I'm not sure if this is the case.

This extension is working fine. Whenever I use image-picker to set an image as a wallpaper then it's working. But whenever I get the image using the phone image path then I'm not able the set that image as a wallpaper. Getting runtime null error.

Please use your package name.
Thank You

Hi there,
The problem is probably within these blocks.
The socket is meant to be a string, not a list. I think you need to ask each permission one at a time.

What Android version are you using and are you using the Companion? The companion does not work, and Android 11 - 12 does not have the write permission.

what exactly is the "phone image path"? any example?
If you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...
which means in your case post a screenshot of your relevant blocks...
To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.

Did you declare the SET_WALLPAPER permission under @UsesPermissions in your extension? If you did, I don't think this block is necessary because the permission would be directly declared in the Manifest.
