How to get screenshot of Application on Android Th

Question

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

Answer 1

You can get screenshot from Vysor application installed on chrome browser.To do this follow the procedure below.

• install Vysor in chrome browser.
• Connect PC with Pi using adb connect.
• Open Vysor on PC and enjoy.

Answer 2

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

Answer 3

It's not a "screenshot", but how about mp4 movie instead?

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

Though the recorded movie is not correctly recorded, it's still like a "screenshot". (I cannot get a frame out of it using QuickTime Player, but any other tool might be able to extract it.)

It seems that AndtoidThings supports old limited OpenGL version that unsupports screenshots.
