please help me!
here is error says:

Error:Execution failed for task \':app:mergeDebu
After searching and using lots of suggestions i got a solution for this:
1)I am using nine patch images in my project and android studio doesn't accept abc.9.png image so rename this name to abc.png
2)When i am convert my images to nine patch images one image can't convert properly it shows "Bad Patches" i remove this image and recreate and i solved my problem, this problem is comes when i convert my project eclipse to android studio
3) put this in your gradle aaptOptions.setProperty("cruncherEnabled", false)
Thanks
