app build fails when android phone with USB debugging enabled is attached and app was installed from app store

[dfabulich]

As soon an android phone with USB debugging enabled attached and the app installed from the app store, the Skip-Lite build process in XCode and Terminal xcodebuild fails. Seen with two different phones and can be reproduced each time.

Cause: When an app is installed from the app store it can't be replaced by a developer version app. The same situation with the app originally installed as developer version completes fine.

Thanks to the detailed output from the xcodebuild on the command I could see the cause now, but within XCode it is nearly impossible to find out why it failed to build.

As it's correct to fail here, the solution would be to just forward the error message better to Xcode so it is visible for the user.

xcodebuild` -workspace Project.xcworkspace -scheme "My App" -destination 'generic/platform=iOS Simulator' -skipPackagePluginValidation

Yes, we should provide better diagnostics here. If you run in release mode and have your Android key in your local project (Android/app/keystore.jks and Android/app/keystore.properties) then you can build and run the app over the Play-installed version, but you can't clobber it with something signed with the debug key.

I'm not sure what the correct recommendation should be: we don't necessarily want to instruct the developer to delete their existing app, since that can result in the destruction of data.

I would suggest to display something like: "Build failed to install app on device XYZ. If you don't want to overwrite the app on XYZ, detach it from USB."
