Hi ,

I create application in b4a version 5.5, which has the signature key used by the debugger (it doesn´'t have a private key), I install the apk on several devices, now I update application using b4a version 9.5, however when reinstalling it, the error "App not install" is displayed , both versions of the application must have the same package name because I am using information from the internal memory that must remain when reinstalling the new version.

do you know if the key is the same? 9.5 may generate a different key than 5.5. did you try to install on a device attached to the ide? were there no unfiltered error messages? android usually spills its guts when there is a problem.

Thanks drgottjr , to fix it I replace the file "debug.keystore" from version 5.5 to version 9.5 because the keys are indeed different


I know that in the future I will have to create a private key.

I'll mark it as solved

and why not download b4a 9.8 while you're at it? free now (like the coronavirus air we breathe!)
