Hello
On my tablet Samsung Tab 2 10.1, I have a 32GB external sdcard
It is partitioned into 2 parts
Part 8GB and 24GB Part II
I use File Explorer ES3
I see the 16GB internal sdcard called O, which I can read and write
I see the external sdcard, the first sdcard1 part, which I can read and write
and the second part sdext2, on which I can read but not write.
Why? on sdext2, there are directories and files that have been created, I think, by the system (eg the app directory with all the apk.
Best regards

Writing to the sdcard is becoming more and more problematic. First there isn't any API to get the path to the sd card. Second starting from Android 4.4 it is only possible to write to a specific folder based on your package name.
OK
Thank's

do you mean the
Android/data/My.App.Name/...
or on the external_SD too ?

I red somewhere that the "write right" for external_SD depends on a certificate.
Google and the phone producer does have the rigth, but "Total Commander" can write too ...
Could It be that we need to SIGN the app with a trusted certificate and than it would work ?
