Android INSTALL_FAILED_UID_CHANGED
Sometimes you have to also uninstall the data folders. For me, I had a package in userspace of com.kikin.cts, and also a folder directory in /data/data/com.kikin.cts. Kept getting INSTALL_FAILED_UID_CHANGED, but after removing the data folder, the error went away.
For rooted devices:
Run the below command
adb rm -rf /data/data/<your.package.name>For non-rooted device:
- Change the ApplicationId of the app. Refer this link to changeApplicationId.
- Build and install the app. App will install successfully because it is treated as new app.
- Now uninstall this app. Which will clear the data.
- Now change the ApplicationId to the previous one.
- Build and install. Magic.. It will install.
Restart your device, and clear your project.Basically , uninstalling would have done this for you in case if doesn't then try restarting.
