如何在Android Studio中或通过ADB在Android Things设备上获取应用程序的屏幕截图？ [英] How to get screenshot of Application on Android Things device in Android Studio or via ADB?

问题描述

是否有任何方法可以在 Android Studio （或通过 ADB ）中获取Raspberry Pi 3 Model B的屏幕截图并带有 Android Things Developer Preview 吗？ （也可以通过 Android Studio / ADB 接受其他方式）。

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).

推荐答案

这不是屏幕快照，而是mp4电影呢？

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

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

尽管录制的电影未正确录制，但仍像截屏。 （我无法使用QuickTime Player提取框架，但是其他任何工具都可以提取框架。）

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.)

似乎AndtoidThings支持旧的有限OpenGL版本，不支持截图。

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