    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}
repositories { mavenCentral() }

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:support-v4:21.0.3'
compile 'com.parse.bolts:bolts-android:1.1.4'
compile 'com.facebook.android:facebook-android-sdk:3.23.0'
compile 'com.parse.bolts:bolts-android:1.+'
compile fileTree(dir: 'libs', include: 'Parse-*.jar')
}

It is because you have included 'com.parse.bolts:bolts-android:x.x' twice in your dependencies. Remove any one of them and the problem will be resolved.
