Hi all, actually when we install android-sdk-update-manager is installed in /opt, but is read-only, android studio requires can write in the folder to can works, or we can't create projects..., save the sdk in the user i think is a bad idea, because every user will need download every time the SDK(13GB), maybe some group to set the write access for android update and android studio?

Thx Cya.

This is a semi-fundamental problem.  You can "fix" this using xattr, for example, but it just means that regular users will be able to scribble all over portage's files, which is not how gentoo package maintenance is supposed to work.

AFAICS the "correct" solution is a painful one for the maintainers -- we might see something like this some day but I wouldn't hold my breath:

All of the SDK components should be broken out into a nice hierarchy of Gentoo ebuilds

The GUI sdk updater should be disabled and somehow tricked into thinking android studio is always up-to-date

Likewise for the NDK and AVD-manager

The various emulator mesa crashes should be resolved by de-vendoring and supplying corresponding dependencies in ebuilds.

the dir is already set with the "android" group tho?
did you add your user to that group?

# ls -ald /opt/android-sdk-update-manager/
drwxrwxr-x. 17 root android 18 Apr 10 19:08 /opt/android-sdk-update-manager//

# grep android /etc/group

try something like this:
# usermod -a -G android username
then logout and back in

The "android group" approach will work better if your directories are sgid recursively and your umask is set to, i.e., 002.

To support a multiuser (and sometimes just a single-user) installation robustly, you'll need to use the xattr equivalent:

Gory details/tutoria:

Ultimately, I've only been able to make android studio fully work, and keep working through updates, by removing all the Gentoo packages and letting Google's installer run amok as my user account; so now I just wait resignedly for them to start mining bitcoins or whatever... :)
