    }



    repositories {

我的项目Gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    }
    dependencies {

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

尝试获取令牌时我的日志输出

我正在我的应用程序中实现推送通知，但是当我调用 GcmIntentService 时，我收到了我已经在我的日志输出中发布的错误。我也尝试使用 FCM 但遇到了同样的问题。如果有人实现了这个，那么请帮忙。提前致谢。

**> 得到我问题的答案错误是因为使用播放服务

9.0.0

But when we update the play service to 9.4.0 and same as firebase dependency .and the main issue in my gradle is apply plugin: 'com.google.gms.google-services' will not come at the top of gradle it will come at the bottom after dependency .And i dont know why this works fine and my token and context compact issue also got resolved.**

apply plugin: 'com.android.application'
    apply plugin: 'android-apt'

    android {
        compileSdkVersion 24
        buildToolsVersion "24.0.2"

            multiDexEnabled true
        }
        //====================Add below two line=============
        dexOptions {
            javaMaxHeapSize "4g" //specify the heap size for the dex process

        compile 'com.google.android.gms:play-services:9.0.0'
        compile 'com.android.support:support-v4:24.2.1'


    }

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

    repositories {
        jcenter()
    }

应该是这样的。 :)
