Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.* signatures do not match the previously

problem description:

Performing Streamed Install
adb: failed to install app-debug.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.*.app signatures do not match the previously installed version; ignoring!]

encountered this problem when installing the phone application from the command line adb install-r app-debug.apk.

reason: the previous version is already installed on the phone, and the application may not be found on the desktop, but there are directories and cache files in the phone system. Many other approaches were tried, and the problem was eventually solved by executing the uninstall command.

solution: run the command adb uninstall com.*. App uninstall the program, and then execute adb install-r app. debug.apk, the program is installed successfully.
