Android Studio Error - libpng error: Not a PNG file

Well... it's not a PNG file! Or just possibly it's a PNG file but not a supported variant.

If you would like any more info then you will have to upload the file somewhere and then post a link. It's impossible to tell anything more without it.

EDIT: Now that you've uploaded the file, I can see that it's a JPEG! It has a .png extension, but it's not a PNG file.

Android studio How to resolve Error in png files of library added

Try to remove "builds" folders and do rebuild. But soon, the whole thing in a long file name. Read this answer. By the way, you looked logs? Maybe this is not the PNG? You have not sent the log and did not specify the version Gradle.

Believe me, iOS developers have own problems.
