I used to have Google Play Services for AR installed and working on my Samsung Galaxy tab. At some point it stopped working and whenever I tried to use Google Model Viewer it would attempt to install the Services again. Regular installation through the Play store didn’t work so I uninstalled the old package and then went to the Github releases page to get it. The latest version 1.44.0 says it conflicts with other (unspecified) packages. Older APK versions say they are invalid packages when I attempt to install. What do I need to do to get ANY version running again?
