[manishpamnani169]

In this project there are no errors whatsover but the OUTPUT of mine
differs from that of the original.

HERE is the original tutorial link:-
https://developer.android.com/training/animation/screen-slide.html

and HERE is my code:-

https://gist.github.com/pamnanaimanish169/3125f456c200430c474c8d1f7690c0b6

Machine Enviornment:- Windows 10(64-bit)

Android emulator:-Nexus 4 API 21

I executed the app and it run successfully and gave the output:-

"my_ouput_screen_slide_new.jpg"

while the expected output is:-

"anim_screenslide_gif.gif"
