I'm looking to uninstall a custom watch face from a running emulator without resorting to wiping the emulator and rebooting. Which ADB commands might I send to the emulator to perform this task?
Just like any Android device, you can use adb. From a command line:
adb uninstall com.your.package.name
If multiple devices are connected, get their names with adb devices
and then use:
adb -s device-name uninstall com.your.package.name
