As I am releasing a new application any day now (Kludd) I was in need to record some gameplay from the app in order to do some kind of video promo. I had no idea how to record from a telephone (I knew how to take screenshots on my Samsung Galaxy S4 which was by holding down the on/off-button and the home button simultaneously) so I googled it.
I found that you could do it using your Android SDK. These are the steps in short:
* Connect your android phone to your computer
* In a command prompt, step into your android sdk directory and then platform-tools directory
* Enter the following command:
adb shell screenrecord /sdcard/FILENAME.mp4 (cancel/end the recording by pressing CTRL + C)
After that either go in on the phone via your computer explorer and enter /Phone/ and you’ll find the video there or find it using whatever exploration app you want on the phone.
