Android Question [Solved] Problem update app in the same package

[Julio Ochoa]

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.

I think that you need to uninstall the old version and then create the new one.

But the data in the internal memory would be lost

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.

looks like some change was made regarding the debug key at version 6.30. mentioned way down the list. not sure what the change was, but it looks like your 5.5 debug key doesn't match your 9.5 key.

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!)
