Error:Execution failed for task ':app:mergeDeb

currently I am using Android Studio 2.1 when I run my App it shows me some error in Message Gradle Build saying the following

I tried cleaning and rebuilding it but it didn't work. The answer for this question didn't work also. Any help would be appreciated, thanks.

Updated: Here is the log output

* Exception is:

In the individual apps's build.gradle, section android {}, insert :

aaptOptions {  
    cruncherEnabled = false  
}

Reference

回答2:

All problem was a crashed png image in one of my drawable folders. I mean the images which we sometime face in windows photo viewer, like the one below:

I dropped the image from the folder and all problem got solved.

回答3:

Try running gradle from command line:

gradle clean build --debug

And post your log afterwards.

回答4:

Just check this link - Android Studio - mergeDebugResources exception and libpng error: Not a PNG file Error Showing In Android Studio

You can try this command as well sudo apt-get install lib32stdc++6 on the console if you are working on a linux machine, then restart android studio and run your project

回答5:

For me, it was a corrupted PNG file. Go to your res folder and try to open every images.

回答6:

Actually, image file something wrong. Go to (drawable) and remove image or replace with new image.This will solve problem.

In addition, you can put method in (build.gradle), but This will not solve the problem but good way to catch up what was wrong.

In build.gradle, section android {}, insert (cruncherEnagle = false)apptOptions.

回答7:

compress the project file and delete prjct. and extract it and open

回答8:

In my res folder I created a 9PNG file. After deleting this file everthing is working fine.

回答9:

Browse Through Your Project Manifest and Resource Files to see if there is an error in the Images you are using. (I was missing the roundLauncherIcon).
Check if all the images that you are using are actually existing.

回答10:

For me, I was getting this error because the full path to the folder was longer than allowed by Windows. I moved my build to a shallower path and this error went away.
