I am developing an android app where I am in need of design support library so when I add implementation 'com.android.support:design:27.1.1'
into my build.gradle(app) then the following error appears:
Caused by: org.gradle.internal.UncheckedException: java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource compilation failed MyAppDirectory\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:2489: error: duplicate value for resource 'attr/itemBackground' with config ''.
But when I remove the dependency implementation 'com.android.support:design:27.1.1'
then the error disappears and gradle build successfully.
My Project build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
// classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.android.tools.build:gradle:3.3.0-alpha04'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
My app build.gradle
apply plugin: 'com.android.application'
android {

defaultConfig {
applicationId "myapplicationid"

implementation 'de.hdodenhof:circleimageview:2.2.0'
}
Note: I have already cleaned and rebuilded the project and I have also invalidated and cleared the cache
By doing some research, I found that MenuView (The Menu in the Toolbar) has defined this attribute.
<declare-styleable name="MenuView">
...
<!-- Default background for each menu item. -->
<attr name="itemBackground" format="color|reference" />
...
</declare-styleable>
I have used <attr name="android:itemBackground" />
instead of
<attr name="itemBackground" format="reference|color" />
to fix this issue.
Please upgrade to version 1.4.1.
