android 4.4 SAF Write file into SD

Question

As you know,I want to save a text file into flash disk connected by otg line.On Adnroid4.4(API19),does it can create directory?I know how to save a file,but it have to click save button.I have a list of files have to save and save into different folders.So can android4.4 can realize this?I do not want to click the save button always.Can i save the file into flash disk directly by uri?

`As you know,I want to save a text file into flash disk connected by otg line`. Sorry. I think i missed something ;-). If you can use the action intent ACTION_OPEN_DOCUMENT_TREE then you can create directories too. — greenapps, Nov 17 '16 at 05:47

If you can pick directories with action intent ACTION_OPEN_DOCUMENT_TREE then you can create directories too.

If you can only pick files (ACTION_OPEN_DOCUMENT) then not.

For every file the user has to act. Indeed the user will become tired. – greenapps Nov 17 '16 at 06:03
