Cannot install Android APK from Crashlytics Beta

Question

After uploading a new build to Crashlytics Beta, users are not able to install

Here's what's happening:

1. User receives an email notification with the latest build
2. Taps "Check it out", which opens Beta by Crashlytics
3. Clicking "Install Update" results in an error "App not installed". There are no additional details

This is happening on both Samsung S8, Android 8.0.0 and Pixel 2, Android 9

I tried uninstalling the existing app on the phone but it didn't make a difference.

Answer 1

You have to disable Google Play Protect from the PlayStore App and enable it again after the installation has succeeded.

Answer 2

Found that the app gets insatlled only if its a released version. I was trying to install on Samsung SM-G975
