How to get a screenshot of an application on an Android Things device in Android Studio or via ADB?

Is there a way to get a screenshot in Android Studio (or via ADB ) for the Raspberry Pi 3 Model B with Android Things Developer Preview on it? (any other way not through Android Studio / ADB also accepted).

This is not a “screenshot”, but what about an mp4 movie?

 adb shell screenrecord --verbose /sdcard/screen.mp4 --time-limit 1

Despite the fact that the recorded movie was not recorded correctly, it still resembles a “screenshot”. (I cannot get a frame from it using QuickTime Player, but any other tool can extract it.)

AndtoidThings seems to support the old limited version of OpenGL, which does not support screenshots.

You can get a screenshot from the Vysor application installed on the Chrome browser. To do this, perform the following procedure.

  • Install Vysor in the Chrome browser.
  • Connect PC with Pi using adb connect.
  • Open Vysor on PC and enjoy.

You can also use Android Device Monitor . Open it from the menu Android Studio Tools -> Android -> Android Device Monitor or run it from the sdk sdk/tools/monitor directory.
