UnsatisfiedLinkError: Couldn't load crashlytic

问题:

After add two lines in build.gradle I have the next exception:

java.lang.UnsatisfiedLinkError: Couldn't load crashlytics from loader dalvik.system.PathClassLoader[dexPath=/data/app/com.creardigitalm.samsungclub-1.apk,libraryPath=/data/app-lib/com.creardigitalm.samsungclub-1]: findLibrary returned null

1. I add the dependency to my project-level build.gradle (apply plugin: 'com.google.gms.google-services'):

apply plugin: 'com.android.application'

apply plugin: 'com.google.gms.google-services'

apply plugin: 'io.fabric'

2. I add the plugin to my app-level build.gradle (classpath 'com.google.gms:google-services:1.5.0-beta2'):

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
        classpath 'com.google.gms:google-services:1.5.0-beta2'
    }
}

Fabric & google-services enter somehow in conflict and I do not know how to solve
