    You have file duplication error. Google says that, according to this answer from en-SO, you need to add this to your build.gradle

     packagingOptions { exclude 'META-INF/ASL2.0' exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' exclude 'META-INF/NOTICE.txt' exclude 'META-INF/LICENSE.txt' exclude 'META-INF/MANIFEST.MF' }
