Android: Drawable not showing up

Seems like this is a bug with android, where sometimes the first image in the drawable folder doesn't show up. Added a dummy image called aaaa.png to the drawable folder and problem was solved. Found the answer here: ImageButton does not display a particular drawable

Had the same issue and resolved it by removing all special characters. In my case it was dashes '-' in the filename:

background-720.png => background.png.

One of the reason is

If you are using Vector file as a drawable left or right then you have to use .

android.support.v7.widget.AppCompatButton

Instead Of

Button

Simple View like Button,Textview doesn't support Vector file as a Drawable left right in my case
