I have face same problem and resolve this issue by configuring proguard rules properly.

What I did here under as below:

First I have excluded google classes from obfuscating like this in proguard-rules.pro:

-keep public class com.google.** {*;}

Second I have enabled this minifyEnabled in build.gradle like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.e2e.quiz"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:recyclerview-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.github.bumptech.glide:glide:3.6.1'
    compile 'com.squareup.picasso:picasso:2.4.0'
    compile 'com.google.android.gms:play-services-gcm:9.2.1'
    compile 'com.google.android.gms:play-services-analytics:9.2.1'
    compile 'com.google.android.gms:play-services-ads:9.2.1'
    compile project(':ast-dst')
}
