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.

you also have to check both V1 & V2 signature versions if signing from Android Studio otherwise it will complain that it's unsigned for some reason.. – Sirenasirenic

I was able to upload unsigned apk to crashlytics by adding: apk_path: – Beamer

Hi Mike, I know how to generate signed APK, and i have generated signed APK successfully, but still facing same issues – Hastings

Are you getting a different warning? – Dunigan

I'm getting the same warning. I have even turned off Instant Run and made sure that I am online – Nigger

Where is this info "Beta for Android only supports distributing a signed APK, unsigned APKs can't be distributed." in the official Crashlytics documentation? Very very poor documentation :[ I had to google it for 1h to find this info – Landmass

I'd recommend contacting support(at)fabric(dot)io with any suggestions for improving the documentation. – Dunigan

Answer 2

Crashlytics not support "Android App Bundle". You can only distrubute "APK" in crashlytics beta.

I was facing this same issue when I was integrating Fastlane with Crashlytics. I wanted to distribute build to testers.

In Fastlane, you can choose whether you want to publish Debug APK or Release APK. Fastlane trying to publish release APK I just changed it to Debug APK in a Fastfile and it worked.

I am sure it might have some settings in Jenkins also that could publish Debug APK. hope this helps.

How can I choose Debug APK to publish? – Leif

@AntonBalashov In a fastfile there is an option like build_android_app(task: "assembleRelease") replace it to build_android_app(task: "assembleDevelop") – Aborning
