Hello Everyone! I want to create an Image Slider that will slide images after some time automatically. The problem is the I have to make this slider above a fragment layer of navigation drawer not the main activity. I have tried to search for many tutorials that can help me but I find none. After struggling a lot, somehow I manged to write my code but in the end I got a Null.pointer Exception causing from viewpager.setadapter(). Can anyone help me in figuring this out or help me creating a image slider. Waiting for your positive reply. Thank you.
