Answer 1

You can use the below code. It works for me.

                        if (SDK_INT >= Build.VERSION_CODES.R) {
                            if (Environment.isExternalStorageManager()) {
                                startActivity(new Intent(this, MainActivity.class));
                            } else { //request for the permission
                                Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
                                Uri uri = Uri.fromParts("package", getPackageName(), null);
                                intent.setData(uri);
                                startActivity(intent);
                            }
                        } else {
                            //below android 11=======
                            startActivity(new Intent(this, MainActivity.class));
                            ActivityCompat.requestPermissions(this, new String[]{WRITE_EXTERNAL_STORAGE}, PERMISSION_REQUEST_CODE);
                        }

And add line android:requestLegacyExternalStorage="true" in menifest file

Answer 2

MANAGE_EXTERNAL_STORAGE

That is only for Android 11 API 30.

You have to start an intent for

Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION

To let the user enable all files access.

For Android 10 API 29 devices

 requestLegacyExternalStorage="true"

will do.

Answer 3

You are not allowed to. Nobody is. No, you can not circumvent this restriction.

You can only access, edit and delete the apps own data. For more read here. https://developer.android.com/about/versions/11/privacy/storage
