Cannot access in folder documents on Android 11 in Delphi XE 10.4.2

[mrceski 0]

I want to read files from documents folder on android in Delphi XE 10.4.2.

Some code work very well in Delphi XE 10.3.3 on Android 10.

Now show message Cannot open file "/storage/emulated/0/documents/Readme.txt". Permission denied.

 

Code:

    WS:=JStringToString(TJManifest_permission.JavaClass.WRITE_EXTERNAL_STORAGE);
    PPS:=jstringtostring(TJManifest_permission.JavaClass.READ_PHONE_STATE);
    RS:=jstringtostring(TJManifest_permission.JavaClass.READ_EXTERNAL_STORAGE);
    PermissionsService.RequestPermissions([PPS,WS,RS],nil,nil);

 

Open file in memo.

Memo2.Lines.LoadFromFile(TPath.GetSharedDocumentsPath + PathDelim + 'Readme.txt' ,TEncoding.GetEncoding(1251));

Why do people keep insisting on using the XE name for things that are not XE?!?  Embarcadero stopped using the XE prefix after XE8.  The current version is "10.4.2 Sydney", period.

Did you read the Android 11 developer documentation?

https://developer.android.com/about/versions/11

 

Google made behavioral changes:
