why i get Some file crunching failed after i rename drawable file to .9.png?

Question

I am testing 9-patch image .
Before everything works fine , and i rename drawable file ic_button_beat_box_default.png to ic_button_beat_box_default.9.png , then i get error :

Some file crunching failed, see logs for details

. Then i rename back , it works normal. So how this happens ?

The complete error is :

* What went wrong:
Execution failed for task ':app:mergeDebugResources'.
> Some file crunching failed, see logs for details

* Try:
Run with --info or --debug option to get more log output.

* Exception is:

Answer 1

On Windows I had a "BUILD FAILED Failed to crunch file [path]" error and solved it by closing the Android Studio project, copying the entire project folder into a location with a shorter directory path, such as my C: folder and then opening the project in the new location. Hope it helps

Answer 2

Rename your file again

ic_button_beat_box_default.9.png to ic_button_beat_box_default9.png because android studio takes ic_button_beat_box_default.9 instead of ic_button_beat_box_default.9.png

or another solution is add below line to your build.gradle(Module:app)

android{
 aaptOptions {cruncherEnabled = false} 
}

Answer 3

I had the same issue by changing only file name, when I saved the image in 9-patch-tool issue solved.

Answer 4

I had the same issue. I was able to resolve it just by reducing one folder from chain. It is due to long file path. So try using minimum hierarchy for your project location.
