In my Android app, the user should have the possibility to save app configuration in a USB stick (and then restore that configuration if necessary).
I managed to open the app Files and select the root of the USB stick connected to the device.
I get the corresponding URI: "content://com.android.externalstorage.documents/tree/A8AC-5853%3A".
Now I have to create a subfolder and write in it two (xml) files but I don't know how to do.
I have found some Java code and some information in the Android Developers site but I'm not able to translate those information into some working delphi code.
Someone can give me some help?
