在我们平时测试工作中，可能需要对 Android 手机进行录屏，第一时间我们肯定想到强大的 adb 命令。但是当我们用 adb 录制的时候，往往会报错 screenrecord: inaccessible or not found

~ $ adb shell screenrecord /sdcard/test.mp4
/system/bin/sh: screenrecord: inaccessible or not found

这是因为现在很多手机为了安全把 screenrecord 功能给回收了，导致我们无法再用该命令行进行录屏操作。
通过adb shell ls /system/bin/命令可以看到ls: /system/bin//screenrecord: Permission denied，说明确实没有录屏权限了。

那么，如果想要录屏怎么办？这里推荐一个工具，那就是 scrcpy

安装 (仅 macOS)：

brew install scrcpy

如果你没有 adb，则需要先安装：

brew cask install android-platform-tools

运行 scrcpy

安装完毕后，电脑连接手机，执行 scrcpy 可在电脑上面看到手机实时投屏：

scrcpy

录屏

如果想要录屏，执行以下两个命令之一：

scrcpy --record test.mp4
scrcpy -r test.mp4

你也可以在不开启实时镜像显示的情况录屏：

scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
