Android 4.4 (KitKat) was released recently, and included along with many of the fixes and improvements was the ability to easily record the screen of the device. Previously one had to awkwardly (trust me I did it) record the device using a second camera, or have a jail-broken device. Built-in screen recoirding is a nice addition for us Andromo Developers because it allows us to easily improve our Google Play app listing, and hopefully get more downloads.
In a nutshell you need the latest Android SDK and Platform Tools installed (you can read about how to do that on the Android Developer site) and then you issue the following command via the command line/shell:
adb shell screenrecord --bit-rate 8000000 /sdcard/yourfilename.mp4
Note: One of the reasons I mentioned Phil’s post is because he recommends increasing the bitrate, I have tried it and it does look nice.
When you are done demonstrating your app CTRL-C will cancel the screen recording.
You should also take a look at the official Android Platform Tools documentation on recording a device screen to see all of the screen recording options. What I like about the Android documentation is that it details an easy way to copy the file from your Phone or Tablet:
adb pull /sdcard/yourfilename.mp4
Once you have the MP4 file, upload it to YouTube, and then add it to your Google Play store listing Graphic and Image Assets, and you’re done.
Here is an example video I made of a sample Andromo app:
