为什么屏幕录制得到错误，当我的屏幕，命令行记录 [英] Why does screen recording get error when i screen recording with command line

问题描述

我想通过以下的这个文章，但我得到了以下错误：

I am trying to do a screen recording of my Android device by following this article but I get the following error:

adb shell screenrecord /sdcard/demo.mp4
/system/bin/sh: screenrecord: not found

我的Andr​​oid设备正在运行版本4.1.2。

My Android device is running version 4.1.2.

推荐答案

从您链接的文章：

Android 4.4系统增加了对屏幕录制，并提供了一​​个屏幕
  记录工具，可以让您开始和停止录制设备上
  这是连接到你的Andr​​oid SDK环境通过USB。

Android 4.4 adds support for screen recording and provides a screen recording utility that lets you start and stop recording on a device that's connected to your Android SDK environment over USB.

现在的Andr​​oid 4.1.2不是4.4，所以这就是为什么所需的二进制文件无法在设备上找到。

Now, Android 4.1.2 is not 4.4, so that's why the required binary is not found on the device.
