Hi...
at the start of my app I ask for permissions
no error there, I know because 2.swa is just txt file where I store some data. I can read it later.
but when I try to rename it using
rename returns false.
It looks like image is saved. Tried to browse all my folders, I know I can not find DirInternal. Can it be that I need some more permissions?
On my Huawei RNEL21 code working OK, but have problems with some other devices. And also, are files stored in DirInternal there forever, is that folder something like cash?
thanks
