it helps some times It looks like the version of fabric build tools in your build.gradle is set to something like classpath 'io.fabric.tools:gradle:+' which means it always uses the newest available version. The current version 1.26.0 seems broken so you can temporarily set exact version to 1.25.4: classpath 'io.fabric.tools:gradle:1.25.4'.
What are the version numbers shown on Fabric Crashlytics crash status view?
I wish this help you That's your app version number and build number. E.g. 1.2.3(2) is version: 1.2.3, build 2. The range is there to indicate that the crash has happened in multiple versions of your app. So the earliest version (where the crash has been logged) is 1.2.3(2) and the latest version (where the same crash has been logged) is 2.0.1.
hop of those help? So, after some digging and help from Firebase/Fabric people, I've resolved this issue. It appears that I had too many active versions for my app, Crashlytics was tracking too many versions and couldn't show some more.
