Android Question Can I use mac address?

[darabon]

I need to use a unique id for each user and save it in server
The device id is not good for my app because it will change if the user uninstalls it.
The best option is the mac address
Can I use it for my app without limitation Android?

No. It is inaccessible on newer devices.

There isn't any ideal id. The android_id does meet your requirements: https://www.b4x.com/android/forum/threads/get-unique-id-for-user.124396/post-776882
However it isn't very reliable and will not work on all devices.

FirebaseAuth might be a better solution.

Yes, It is a good solution but I think all users don't have Google account and make a problem
