I a signed my appication with a new certificate and set password. When I tried to upload a beta version of my app to Developer Console (google play). An error message appear asked me to change my package name because the default com.example.xxx is not allowed. I changed the package name. but after that when I try to build and run my app. I get the following error.
Error generating final archive: java.io.IOException: Keystore was tampered with, or password was incorrect
Any Ideas?
