Error with fortuneball tutorial

Error:(28, 22) No resource found that matches the given name (at ‘src’ with value ‘@drawable/img_crystal’).

Are you sure you added the image file? Or wrote the name correctly?

Thank you for your reply, I am doing a tutorial and did a complete cut and paste for this section.

I am not sure where to look for the image file if that was not in the tutorial. I am studying the code for errors. The name of the tutorial is:
Beginning Android Development Tutorial: Introduction to Android Studio
Any help would be awesome…

I found my mistake in not adding the images to the drawable hdpi thru xxhdpi and I have corrected this error. The build is success but the run does not work on my emulator. I will work on this, thanks for your help!

Glad you got it worked out!
