Good night, the main problem I'm having is the following and the only difference is that the source code was applied to another computer:
Installation failed with message INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package hubotec.jmugi.gmocis signatures do not match the previously installed version; ignoring !. It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
