I have heard that Android KitKat restrict app's write permission to the SD Card, however, on my Moto X Android KitKat 4.4.4 device, my app still can write(create folder) without any problem.

I know there are different version of KitKat

4.4

4.4.1

4.4.2

4.4.3

4.4.4

Thus, I would like to know which version of KitKat restricts an app from writing to SD Card? I would like to inform the user that their Android OS version is not supported for certain functionalities.

thanks, any comments and suggestions would be appreciated.

The tests for blocking write access to removable media in the Compatibility Test Suite were added in the Android 4.4 edition of the Suite, according to Dave Smith. Hence, devices that ship with Android 4.4+ should not allow write access, but devices upgraded to 4.4 from earlier versions of Android may retain write access.

However, as JoaoBiriba points out, this is for removable storage. The Moto X appears to lack a removable media card slot. You may be testing with external storage, which is something else entirely and may have nothing to do with an an "SD Card".

Moto X has not SD-Card, only internal storage so this is not blocked
