Question
This may be the wrong area but is this fix good for most tablets? I have the onda vi10 elite running ics 4.0.3 and most programs cant write or even see the sd card. Any suggestions?

Simple solution for external sdcard write access on Android 3.2...if you're rooted

I've found a simple solution for gaining write access to the external sdcard (/mnt/sdcard2) on Android 3.2. The sdcard is mounted r/w, but the owning group is media_rw which is linked to the WRITE_MEDIA_STORAGE permission. Unfortunately, this permission was not required for access to the external sdcard prior to 3.2 so most file management utilities do not request it when they run...meaning they only have read access to the card.

The simple solution, if you're rooted, is as follows:
1. Using a root-enabled file manager, navigate to /system/etc/permissions and make sure you have mounted the file system r/w.
2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.
3. Add an additional group definition for this permission...<group gid="media_rw" />
4. Save the changes to the file.
5. Restart your tablet.

After this change, any apps that request the WRITE_EXTERNAL_STORAGE permission (which includes almost anything that access either of the sdcards) will gain group membership in both sdcard_rw AND media_rw, giving them r/w access to both sdcard filesystems.

Thank you so much. This worked on my Galaxy 7 Plus. I just wanted to edit and save to sd card.

No idea what I'm doing wrong. Galaxy Tab 7 Plus, rooted, added the line <group gid="media_rw" /> but that made no difference. Using App 2 SD and it still says no card. Any ideas?

Someone please correct me if I am mistaken but as far as I know apps can not be moved to the sd card in Honey Comb correct?

If so that is why that particular app is saying there isn't a card.

Dumb question, but how do you "make sure you have mounted the file system r/w'?
