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

My Android device is running version 4.1.2.

回答1:

From the article you linked:

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.

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

the article you linked is about the new APIs include from Android KitKat 4.4. if your device runs a lower version of Android, you cant run these new features.
