I tried to reinstall an apk

$adb install -r new.apk

And it shows the error:

Failure [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES]

One solution is to uninstall and install the new.apk, that works fine.

But I'm wondering whether I could re-build an apk and re-install without the uninstallation. Eg. change some config in the AndroidManifest.xml, or not sign the APK, etc.

It would be great appreciated if you could tell me the whole meaning of the "INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES".

It means the new copy of your application (on your development machine) was signed with a different signing key than the old copy of your application (installed on the device/emulator). For example, if this is a device, you might have put the old copy on from a different development machine (e.g., some other developer's machine). Or, the old one is signed with your production key and the new one is signed with your debug key.
