AAPT err: libpng error: Not a PNG file

Question

After updating Android Studio 2.0 with Gradle version 2.10, I am getting this below metioned issue.

Note:The same project working fine in Android Studio 2.0 with Gradle version 2.8

I have reviewed all my images, don't know what will be the problem.

The same problem has posted in code.google.com

Is that 1563428392 a resource id? If so you can check what resource is giving you that error. — Pedro Oliveira, Apr 22 '16 at 07:50
1. Delete the whole `build` folder from root and from within app and try again. 2. If #1 doesn't help: run `gradlew assembleDebug --stacktrace --debug` from command line which will likely output the exact command/file name causing the problem. See [Logging](https://docs.gradle.org/current/userguide/logging.html). — TWiStErRob, Apr 22 '16 at 08:18

At last, I resolved the issue with the help of this link refer link

Goto terminal and execute the below mentioned command to know the details about the issue

gradlew assembleDebug --info

It will show you the info about the issue or warning. In my project i have got some issues like, some files crunching failed issue.

Steps to resolve:

Install the ImageMagick tool download
To remove the iCCP chunk from the PNG image

Click down the "Shift" key and right click on the folder which is having images

Select "Open command window here" option

In the command terminal type mogrify *.png

(e.g. D:\AndroidProjects{your_project_folder}\app\src\main\res\drawable-hdpi>mogrify *.png)

Now go to your project terminal execute the command gradlew assembleDebug --info,Hope all your warnings and failed to convert issues are removed.
