Sign Android apk with jarsigner options


I am trying to use the sign-apk step on bitrise but I am getting the following error:

“Failed to sign APK, error: [jarsigner error: unrecognized algorithm name: SHA1withRSA (weak)”

When trying to pass any jarsigner_options bitrise seems to ignore them.



Hi @konstantino7,

Can you please include the whole build log or an URL to the build?

Hi @BirmacherAkos

This is quite urgent for us.

Thanks, konstantino7

This was resolved via the onsite chat, right @BirmacherAkos @konstantino7?

Yes indeed thanks.


We have released a new version (1.2.1) Sign APK step.

It has the fix for this issue.
