My Android apk was developed by XE7. Now I upgrade the project with XE8.
The IDE report a signing certificate error when install the apk to Android device:
Unable to create process: Unable to install
Embarcadero’s solutions are:
Manually uninstall the previously-installed application from your Android device.
Configure RAD Studio to perform a clean install every time that you run your application.
I think that these are not good solutions. Because my apk has been installed in many phones, I can’t require the user to manually uninstall or do a clean installation.
who have a better solution? or can my apk use a same signing certificate?
