Resources$NotFoundException while starting the sample app

[bakikocak]

I have downloaded the code and tried to run sample app. I was not able to run it as I got the message below. I tried clean and rebuild since it was suggested on several pages but did not work out. Any help appreciated. Thanks.

Note that MainActivity.java:35 refers to setContentView(R.layout.activity_main);

The error i got:
