Disabling AAPT2 will not fix the issue. It will only postpone it for a bit since AAPT1 will be deprecated soon. Post the full build log and the AAPT errors you're getting so we can solve the underlying issue — Izabela Orlowska, Apr 03 '18 at 10:54

Check your PNG images, corrupted maybe or not real png (jpeg for example)

You can get the list of unreal PNGs by typing following command in android terminal

find . -type f -name "*.png" | xargs -L 1 -I{} file  -I {} | grep -v 'image/png; charset=binary$'

What if there are no corrupted png files? – Arctic45 May 14 '18 at 10:37

Check the log, here "com.android.builder.png.AaptProcess$NotifierProcessOutput.handleOutput(AaptProcess.java:443)" it's about png – nasser Jul 02 '18 at 16:06

This is what I get: 'xargs' is not recognized as an internal or external command, operable program or batch file. – JohnA10 Jul 25 '18 at 21:10

    //builds,
    // but continue the build even when errors are found:

    abortOnError false

}

buildTypes {
    release {
        aaptOptions.cruncherEnabled = false
        aaptOptions.useNewCruncher = false
        minifyEnabled false

Add the following statement to your gradle.properties file:

android.enableAapt2=false

Also make sure to update build tools, gradle plugin and gradle version.

I am getting The option 'android.enableAapt2' is deprecated and should not be used anymore. Use 'android.enableAapt2=true' to remove this warning. – user3555472 Apr 03 '18 at 03:41
And the same issue facing – user3555472 Apr 03 '18 at 03:41
does 'android.enableAapt2=false' resolve your issue? Ignore 'android.enableAapt2' is deprecated warning its a Android studio bug. – 0xAliHn Apr 03 '18 at 03:49
Resolved my Issue, It was because one of my .png file Thank you for help, appreciated – user3555472 Apr 03 '18 at 06:15

@user3555472 png file in which context you are telling please explain – Shweta Nandha Apr 04 '18 at 12:19
My PNG image was corrupted. – user3555472 Apr 11 '18 at 06:16
This is a very bad answer, it's not only deprecated, it will not solve the problem from the source. – nasser Oct 08 '18 at 02:59

i just change minifyEnabled to false .

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

At build.gradle file, make minifyEnabled false

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

And also remove this line from gradle.properties file

android.enableAapt2=false
