ADB is useful for
other things in addition to debugging. Taking screenshots on wearables
is not as trivial as it seems. The “Take wearable screenshot” option in
an Android Wear companion app allows only sharing screenshots through
mail or social networks. You can use ADB as another way to save images
of wearable screens on your PC.
adb shell screencap -p /sdcard/screenshot.pngadb pull /sdcard/screenshot.png
Notice
that even on round dials the screenshots are actually square. You
should keep this point in mind to improve your apps’ usability.
