Change Serial Number (ro.serialno) on Android Virtual Device (Emulator) on Apple Silicon

Hi everyone

I am using the Android Studio Preview Version and thought, maybe this is the right place :)
I need to change the Serial Number (ro.serialno, and other IDs) of an emulated Android Device. There are not many ressources concerning that issue.

Ideas:

• Change it by adb shell (setprop ro.serialno=123), but it is a read only property
• Add serial number by kernel parameters (emulator -avd my_device -prop ro.serialno=123456 -no-snapshot-load), but I get a warning: WARNING: unexpected '-prop' value ('ro.serialno=123456'), only 'qemu.*' properties are supported
• Change the Number by editing the emulator (or virtual device) in a hex editor. But I could not find, where it is stored

Do you have any ideas?

Environment: MacBook M1, Android 11, arm64-v8a (Api-Level 30)

Thank you very much!

Have you managed to find solution to your problem? Having the same issue and would appreciate any help.

No :-(

Any update on this? I'm basically at the same point @simonhuwiler was. I tried rooting the emulator and setting the serialno via setprop and also via the kernel params, but no luck.

Would love to know if you ever solved this @simonhuwiler

@fielding Unfortunately not. I switched to a real device.
