Android Question apk certificate have changed after updating B4A ?

[jnbarban]

hi, we developed our application from B4A 3.8
All deployment was good and the apk installing succesfully on client tablet.

Since updating to B4A 6.80, our apk can't be installed on client tablet because tablet say that the certificate are different.

We haven't never create any certificate before. how we can product the new apk with the same certificate as the old version ?

thanks

Do you mean a "private sign key" for a certificate?

Are you sure you did not create a signature?
If you've published it on Google Play, you've definitely created it because otherwise you would not accept the App

My guess is that you used the default b4a debug signkey. This key changed in one of the last updates. IIRC Erel provides the old key somewhere.

Yes !!! that excactly wath we want. Thanks An Schi and Erel.
Effectively, we have never publish our application on market, so we have use only the debug sign key.

Thanks, you save my work day
