Android Studio Error - Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT error

Question

This is my build.gradle (Module:app) file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    aaptOptions.cruncherEnabled = false
    aaptOptions.useNewCruncher = false

    defaultConfig {
        applicationId "com.doctor.ciao"
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:design:26.1.0'
    compile 'com.felipecsl:gifimageview:2.1.0'
    compile 'com.github.devlight.pulseview:library:1.0.2'
    compile 'commons-io:commons-io:2.4'
    compile 'com.github.lguipeng:BubbleView:1.0.1'

}

I am getting two errors:

1. Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT error

2. Error:Execution failed for task ':app:mergeDebugResources'.

   Error: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT error

I have already added "android.enableAapt2=false" to gradle.properties file but still the error persists. Please help me with this issue. Thank you

My issue was that I had an invalid png file - I had a .jpg file that was accidentally renamed with the .png extension

To find the offending image file I ran this command in my app directory:

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

Renaming the image file to a .jpg extension solved the problem and I could build again.
