You cannot create "create new folder on SD card". You can create a new folder inside some other folder that the user chooses, but you cannot force the user to choose removable storage.

To create a new folder inside of some other folder, this should work:

1. Start an activity with startActivityForResult() on an ACTION_OPEN_DOCUMENT_TREE Intent, to allow the user to choose a folder. Include FLAG_DIR_SUPPORTS_CREATE to ensure that you can create something new in the folder.

2. In onActivityResult(), wrap the Uri that you get in a DocumentFile, then call createDirectory() on it to create a new folder as a child of whatever the user chose.
