google-play-services.jar
gson-2.1.jar

And this is my gradle file

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 21
    buildToolsVersion '21.0.1'

        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

Answer 1

The class android/support/annotation/AnimRes is included twice in your project, maybe in two different libraries. You need to find it out what is and exclude one of them.
