Adb uninstall apk file description

I was using adb yesterday to uninstall the program. The command and system prompt I entered are as follows:
[Plain]
Arthur @ arthur-laptop :~ $ Adb uninstall com.hase.bclm.client-2.apk
Failure
Later I found that when I uninstalled the program, only the package on the end of adb uninstall should be the. APK file, but the package name, that is, the name specified by the package element under the <manifest> node in the AndroidMainifest. xml file, is as follows:
[Plain]
Arthur @ arthur-laptop :~ $ Adb uninstall com. hase. bclm. client
Success
The suffix "-2" is no longer needed, because it is not part of the package name, and is automatically added by the Android system during repeated installation.
