ADB install-r Installation Application error [Install_parse_failed_inconsistent_certificates] and how to apk system signature _apk installation failed

[Install_parse_failed_inconsistent_certificates]

The reason is that the APK signature problem is caused.

If the app's androidmanifest.xml adds android:shareduserid= "Android.uid.system" (adding this property as a system application into the system, you can modify the system time, etc.)

Because the app runs in the system as a system application, the installation fails due to inconsistencies in his signature and system signature

These three can be obtained in the source code
