How to record screen in android from inside or outside the app?

Question

I see some apps on Google Play which allow you to record entire screen for Android version 5.0+ I have been digging into android reference for a while but could not figure our a right way to do it. Could someone please provide me just a small hint ?

Also, I understand Android system won't give you full screen buffer access for version < 5.0+, However is there any way to just record my own app's screen cast within the app ? One approach I came up with is to take snapshot of the screen few times every second and put them in encoder to create a video, however, this looks like a very heavy approach. Can anybody please suggest a better way to do it ?

Do you need it as a feature in the app or just want to record for purpose of making a video of the app a single time? — Msk, Apr 10 '15 at 17:22
@Msk - Yes, I would like to incorporate it as a feature so that app users can record their session and upload it on server. — Amit Gupta, Apr 10 '15 at 17:24

Thanks for your answer. However, how can I do it from inside the app ? It's a shell command, can I invoke it from java ? – Amit Gupta Apr 10 '15 at 17:29
Hey @Sai , Your edited answer was helpful. Do you think taking 16 screenshots per second ( 16 fps ) will be a good idea ? – Amit Gupta Apr 10 '15 at 17:48
@AmitGupta If i were you, I would check myself – Sai Phani Apr 10 '15 at 17:51
