CREATE FILE AS PER MRS ANKE METHOD .aia (63.9 KB)
my aia file attached thanks mrs Anke

Hello,
I have tried AS IS the app CREATE FILE AS PER MRS ANKE METHOD by KHALED_MOSTAFA on my Android 14 phone (Realme GT 6). It works fine, but when I copy the text file, I get READ_EXTERNAL_STORAGE permission denied error, but the file is eventually copied successfully. As natural, I granted any read/write file permission to this app in its operating system settings.
In am really interested in finding a solution to such issue, as I have several old apps that are no longer working on new Android version and that I need to make running again.
Any help will be very appreciated.

Did you use the File component? Some methods mistakenly request READ permission. Try to use one of the File extensions from @Taifun or @vknow360 instead.

Hi Anke, thank you for your prompt feedback.
The app already uses Taifun file extension to copy the file, it is there indeed I get the error:

Per your suggestion, is it possible the error comes from MakeFullPath or Exists method of File component (used in the Copied event)?

71

Try the TaifunFile.Exists method instead:

just ask for MANAGE_EXTERNAL_STORAGE permission only once
you can store a flag in TinyDB after the permission has been granted

ok, thank you very much

I now added a method into my tools extension, which can check, if manage external storage opermission already has been granted

HasManage

You can download the tools extension in the Download section here App Inventor Extensions: Tools | Pura Vida Apps

Example use

@Anke might want to add that method into her All Files Permission extension

  @SimpleFunction(description = "Checks, if MANAGE_STORAGE_PERMISSION has been granted. Returns true or false.")
  public boolean HasManageStoragePermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
      if (Environment.isExternalStorageManager())
        return true;
      else
        return false;
    } else
      return true;
  }
