Answer 1

For all versions you can store to: storage/emulated/0/Android/data/APP_PACKAGE/.

Or in general to getExternalFilesDir() .

Also for all versions you can store to:

File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS)
       , "MyFolder");

Update: getExternalFilesDir is not private on Android Q-;

For an app private storage location for all versions use getFilesDir() .

For media use getExternalMediaDirs() available since Lollipop but not private on Q- And not private on higher versions for apps with MANAGE_EXTERNAL_STORAGE. And never for file manager apps.
