I have my license file but need to sign a new rise to my Google Play but made with another firm because it was made with other software application.
I can prove that I own and dispose of the data needed to realize this.
Thank you for your support
But Google Play shows me signing my app like this in my keystore file. and I need to change in order to update that will not let me.
See if this illustrates my problem better
A user created by my ascended the app created on a different platform to B4A and now need to upload the new version created with B4A and signed with the same SHA1 than the first.
I wish I understood
