Android Studio crash (aapt.exe returns 42) when I put PNG file in drawable folder

Question

After yesterday's update it won't build or run project with these 2 PNG images as background image. As soon as I delete these images everything works fine again (I put images in drawable folder).

:app:mergeDebugResources FAILED

This can also happen if you exceed the Windows max path length.

If 'yesterdays update' refers to Android 5.1 (API 22) then try using the latest version of the build tools. Adjust your build.gradle to use buildToolsVersion "22.0.0"

Solved it for me, thanks. Why does Google keep breaking stuff? – fweigl Mar 19 '15 at 10:33
This is not help! The actual problem is the limitation of file length (include path) as Herrbert74 answer. – Phuong Jan 22 '16 at 04:02

In my case, it turned out that the "png" image was really a "psd" image that simply had the wrong extension. I had to convert it to a "png" and then the error went away.

This can happen when gradle fails to process resources.

In my case it happened to be an invalid image file in the drawable folder, that's why my XML layouts that Android Studio didn't pick up on ... for that solution i am prefer both ways

1> check your extension & convert them .png into .jpeg

2> if that useless then delete from drawable

Check the image middle.png. if it is an image with format jpg or jpeg,that is the reason.

We got this error message too. For some reason, our files were named foo.9.png - and the extra dot tripped up the build. So, check if you have any superfluous dots in the file name too.
