duplicate entry: com/android/volley/AuthFailureError.class while compiling project in android studio

Question

I am using external libraries payu money sdk and linkedin-sdk, both uses volley libraries, which while compiling project gives duplicate entry of AuthFailureError.class

Answer 1

I had this problem when I tried to generate the APK (release) and I solved it changing the linkedin-sdk build.gradle:

From:

dependencies {
    compile 'com.android.support:support-annotations:20.0.0'
    compile 'com.android.support:support-v4:21.0.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile files('libs/volley.jar')
    androidTestCompile('junit:junit:4.12') }

To:

dependencies {
    compile 'com.android.support:support-annotations:20.0.0'
    compile 'com.android.support:support-v4:21.0.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.volley:volley:1.0.0'
    androidTestCompile('junit:junit:4.12') }
