I develop android application and when create APk from this application (with Generate Signed APK) and when install this apk in other devices not install and show me this error on phone : App not installed
how can i fix it?
This is usually caused when you have a debug apk that is signed with a different certificate and you are trying to install a release version with a different certificate. If you have a debug apk on the device try uninstalling it and try again.
