Answers:

You can try to add the following line to the bottom in your app’s build.gradle, inside the android {} and below your dependencies {}.

packagingOptions {
    exclude 'META-INF/maven'
}

This will remove unnecessary files during your build, which should prevent your duplicate file exception which is caused by merging your dependencies.

See: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/maven/com.fasterxml.jackson.core/jackson-databind/pom.xml

Solution of my problem was

packagingOptions 
{
exclude 'META-INF/maven/com.fasterxml.jackson.core/jackson-
core/pom.properties'
exclude 'META-INF/services/com.fasterxml.jackson.core.JsonFactory'
exclude 'META-INF/maven/com.fasterxml.jackson.core/jackson-core/pom.xml'
}

duplicate file link copy from error message and past in

packagingOptions 
{ 
 exclude 'past here copied file link'
}
