Android 4.4 KitKat has a shell utility for recording
the Android device screen. Connect a device in
developer/debug mode running KitKat with the
adb utility over USB and then type the following:
adb shell screenrecord /sdcard/movie.mp4
Press Ctrl-C to stop
adb pull /sdcard/movie.mp4
Screen recording is limited to a maximum of 5 minutes.
use a screen recorder, such as SMRecorder.
Instead of using the emulator, which is slow -
especially for games and things you would want a
video of, I recommend using a VirtualBox VM,
with Android installed. You can connect the
Dalvik debugger to it and debug you app there.
If the debugger slows down you app too much,
disconnect it to record the video. There are many links
out there explaining how to set up the Android VM for debugging.
To make the Android phone screen video capture easy,
you can try Wondershare MobileGo for Windows users or
Wondershare MobileGo for Android Pro Mac for Mac users.
The software is mainly designed for manage data on your
Android phone or tablet from Windows PC or Mac. Besides,
both versions let you capture videos, game screenshot on
your Android phone with 1 click.
