Issue
I have just updated emulator 26.0.3, now I cannot run adb root command for new created emulator.
the error shown is below:
adbd cannot run as root in production builds
I have killed and restart adbd like:
adb kill-server
adb devices
Nothing helps, any ideas?
I am not sure what is the difference and how to select different build but,
if following settings are enabled while creating, then it has root.
Solution
To enable root access: Pick an emulator system image that is NOT labelled "Google Play". (The label text and other UI details vary by Android Studio version.)
Exception: As of 2020-10-08, the Release R "Android TV" system image will not run as root. Workaround: Use the Release Q (API level 29) Android TV system image instead.
Test it: Launch the emulator, then run adb root. It should say
restarting adbd as root
or
adbd is already running as root
not
adbd cannot run as root in production builds
Alternate test: Run adb shell, and if the prompt ends with $, run su. It should show a # prompt.
Steps: To install and use an emulator image that can run as root:
- In Android Studio, use the menu command Tools > AVD Manager.
- Click the + Create Virtual Device... button.
- Select the virtual Hardware, and click Next.
- Select a System Image.
- Pick any image that does NOT say "(Google Play)" in the Target column.
- If you depend on Google APIs (Google Sign In, Google Fit, etc.), pick an image marked with "(Google APIs)".
- You might have to switch from the "Recommended" group to the "x86 Images" or "Other Images" group to find one.
- Click the Download button if needed.
- Finish creating your new AVD.
- Tip: Start the AVD Name with the API level number so the list of Virtual Devices will sort by API level.
- Launch your new AVD. (You can click the green "play" triangle in the AVD window.
