How to set a PNG file to an ImageView?

you can also set the image using an xml file with the following attriblute

android:src="@drawable/nochart"

just put your .png file in mipmap folder

Use:

chartImageView.setImageResource(R.drawable.nochart);

I encountered the same problem. The solution for me was to move the ".png" from "drawable-21" to "drawable".
