how to create an Android release build

[David Brown]

I am trying to create an Android release build following https://bitbucket.org/blog/automate-publishing-your-android-application-with-bitbucket-pipelines-and-gradle  and we are hitting a few problems.

I've created a upload key and cert on Google Console and a Google service account.

The output from the Build task (assembleRelease) does not sign the build.  The reason I say this is two reasons, one the APK gets names "unsigned" but more so when I try to upload the APK to Release Management / App Release of Google Console I get an error stating "Error from apksigner: ERROR: JAR_SIG_NO_SIGNATURES: No JAR signatures", which is the same message if I try to upload a Debug build I've built using Studio.   I can manually upload a Release APK built via Studio so I think my Upload key is value.

Any thought on what I may be missing?  Or suggestions of what to look at ... or a working gradle script and pipeline yml would be greatly appreciated.

@David Brown Did you find any solution? I'm also facing the similar issue.

Wasn't able to do it using bitbucket's own ci image, that was still giving me an error but then I used some different image.

You must sign your build with the keystore in order to create a release build
