Android Question External microSD present but not writable

[Abílio Magalhães]

Hello,

My app works fine with all external microSD cards, writing on almost all tablets.

Now I have 2 clients with problems. One is a Lenovo TAB2-A10-30, with Android 5.1.1. and MicroSD card is not present on /mnt

The microSD is at /storage/sdcard1

Bu when I try to write it gives error.

I cannot root the tablet and I really need to write to SDCard.

Can you give me an ideia about the problem?

Kind regards,
Abilio

You should use RuntimePermissions.GetAllSafeDirsExternal to find the path of the accessible folder: https://www.b4x.com/android/help/runtimepermissions.html#runtimepermissions_getallsafedirsexternal

Hi,

I've tried and app still reporting only 1 card when call GetAllSafeDirsExternal.

I've read about different group on permissions but no conclusion.

What could be wrong?

Many thanks for you help

I've read about different group on permissions but no conclusion.

Assuming that you are running it on Android 4.4+ then it is not related to any permission. If this method only returns one path then there is no other accessible storage.
