This is a bug in AAPT2 in Android Gradle Plugin 3.3.0, when building a project with larger png's (around 2-3 mb and up).

@akong9759 created an issue for this on Googles issue tracker and it has been fixed.

https://issuetracker.google.com/issues/117900475

The problem has been fixed in Android Gradle Plugin 3.5.0-alpha03 and the fix is scheduled to be released in version 3.4.0.

A temporary fix for Android Gradle Plugin 3.3.0 has been suggested on the issue. Add the following to the project build.gradle:

allprojects {
    // Workaround for https://issuetracker.google.com/117900475
    // Remove when upgrading to AGP 3.4 or higher.
    configurations.matching { it.name == '_internal_aapt2_binary' }.all { config ->
        config.resolutionStrategy.eachDependency { details ->
            details.useVersion("3.5.0-alpha03-5252756")
        }
    }
}

For me delete all build folders and restart system and reopen Android Studio works in debug mode.

One of my png was giving error : error: failed to read PNG signature: file does not start with PNG signature I open and export again in png. Now it is working with every build variant. And Delete one zero byte png. Anyone make it beautiful if works/ Thanks

You need to clean up your older caches of gradle and maven dependencies. E.g, try to delete the files under .m2 and .gradle and then Invalidate Caches / Restart ...

Also, can try to disable enableAapt2 by setting it to false inside gradle.properties

android.enableAapt2=false

Answer 4

You need to verify your layout.xml files. There may be something wrong. I got same error and fixed issue on layout file. It worked for me.

Answer 5

If you would change variants it would automatically configure itself... Means if you are going run free(Choose from built Variants) then paid flavor will be red and Vice-Versa.
