Tried this, but still crashed when using a .png file. If I try the same thing with a .jpeg file, it works. The same is true (i.e crash) if I try android:background="@drawable/image_name" with a .png file, but works with .jpegs. Any ideas? – Devoir

Fixed. The problem was the image size itself; it was too large. Scaling the image to be smaller did the trick and works from the XML file directly, i.e. android:background="@drawable/image_name" – Devoir

Answer 2

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

android:src="@drawable/nochart"

That doesn't work. It seems that ImageView can't load a png by default. – Exemplum

Doing this works for me if I'm using a .jpeg file. It crashes with a .png file. – Devoir

Scratch my last comment. My problem was the image size itself; it was too large. Scaling the image to be smaller did the trick and works from the XML file directly, i.e. android:background="@drawable/image_name" as a .png file. – Devoir

Answer 3

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