Answer Source

You should add below code to your gradle file :

android {
     packagingOptions { 
         exclude 'META-INF/LICENSE.txt' 
         exclude 'META-INF/NOTICE.txt' 

Edited :

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile ''
compile 'commons-logging:commons-logging:1.2'
compile 'commons-codec:commons-codec:1.9'

Remove jar(commons-logging and commons-codec ) from libs folder and add this gradle dependency.
