android - Unable to upload apk to Crashlytics

Question

I'm trying to automate my app build distribution via Jenkyns and Crashlytics. I configured all as indicated on the documentation but crashlyticsUploadDistributionRelease failed with this error: "Distribution upload failed" and "WARN - Crashlytics halted compilation because it can't distribute the unsigned APK:".

how can I fix it ?

Answer 1

Mike from Fabric and Crashlytics here.

Beta for Android only supports distributing a signed APK, unsigned APKs can't be distributed.

For information on how to sign an Android app, head to Android's documentation here.
