我的文件： 的Android /应用/build.gradle：

dependencies { 
    // compile ('com.google.android.gms:play-services-gcm:9.0.0') { 
    //  force = true; 
    // } 

    compile fileTree(dir: "libs", include: ["*.jar"]) 
    compile "com.android.support:appcompat-v7:23.0.1" 
    compile "com.facebook.react:react-native:+" // From node_modules 
     compile "com.facebook.android:facebook-android-sdk:4.8.+" 
    compile "com.android.support:support-v13:23+" 
    compile ('com.google.android.gms:play-services-gcm:8.4.0') { 
     force = true; 
    } 
    compile project(':react-native-push-notification') 
    compile project(':react-native-sqlite-storage') 
    compile project(':react-native-image-picker') 
    compile project(':react-native-vector-icons') 
    compile project(':react-native-contacts') 


} 
apply plugin: "com.google.gms.google-services"

的Android/settings.gradle

buildscript { 
    repositories { 
     mavenCentral() 
     jcenter() 

    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.2.2' 
     classpath 'com.google.gms:google-services:3.0.0' 
    } 
} 

allprojects { 
    repositories { 
     mavenLocal() 
     jcenter() 
     maven { 
      url "$rootDir/../node_modules/react-native/android" 
     } 
    } 
} 
apply plugin: "com.google.gms.google-services"

任何想法，为什么它不工作？
