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

Instead of this

packagingOptions {

        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'

    }

try this

 packagingOptions {

   exclude 'META-INF/DEPENDENCIES.txt'
   exclude 'META-INF/LICENSE.txt'
   exclude 'META-INF/NOTICE.txt'
   exclude 'META-INF/NOTICE'
   exclude 'META-INF/LICENSE'
   exclude 'META-INF/DEPENDENCIES'
   exclude 'META-INF/notice.txt'
   exclude 'META-INF/license.txt'
   exclude 'META-INF/dependencies.txt'
   exclude 'META-INF/LGPL2.1'

   }

and more thing

Remove this line

apply plugin: 'com.google.gms.google-services'

from Bottom and add to Top after this apply plugin: 'com.android.application'.

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

Update :

just remove

compile fileTree(dir: 'libs', include: '*.jar')

and apply dependencies.
