【问题描述】：
我最近需要在我的项目中使用 Google GCM。从它的website 说：
Firebase 云消息传递 (FCM) 是 GCM 的新版本。它继承 可靠且可扩展的 GCM 基础架构，以及新功能！看 常见问题解答以了解更多信息。如果您要在新应用中集成消息传递， 从 FCM 开始。强烈建议 GCM 用户升级到 FCM， 以便从现在和未来的新 FCM 功能中受益。
为了设置新的 Firebase 应用程序，我按照official website 提供的说明进行了以下操作：
- 在 Web 控制台中创建了一个新的 Firebase 应用，并从那里获取了我的 json - 在提供了我的应用的正确包之后；
- 在顶层项目的 gradle 文件中，我在依赖项部分添加了
classpath 'com.google.gms:google-services:3.0.0'； - 在我的模块的 gradle 文件中，我添加了：
compile 'com.google.firebase:firebase-core:9.0.0' compile 'com.google.firebase:firebase-messaging:9.0.0'，在它的最后一行，我添加了：apply plugin: 'com.google.gms.google-services';
下面提供了完整的 Gradle 文件：
顶级gradle文件：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.7'
classpath 'com.google.gms:google-services:3.0.0'
}
}
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
模块的 gradle 文件：
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
dexOptions {
javaMaxHeapSize "4g"
}
defaultConfig {
applicationId "br.com.gogame"
minSdkVersion 21
targetSdkVersion 23
versionCode 1
versionName "1.0"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
useLibrary 'org.apache.http.legacy'
}
dependencies {
...
compile 'com.google.firebase:firebase-core:9.0.0'
compile 'com.google.firebase:firebase-messaging:9.0.0'
...
}
apply plugin: 'com.google.gms.google-services'
当我启动我的应用程序时，我得到了这个堆栈跟踪：

【问题讨论】：
-
您在崩溃的设备上安装了哪个版本的 Google Play 服务？
-
使用这个代码
getPackageManager().getPackageInfo("com.google.android.gms", 0 ).versionCode;我有这个版本：GOOGLE PLAY SERVICE DEVICE VERSION IS: 9083438. 我在 Firebase 和 Android 中创建了一个新项目，只是一个你好世界，它工作.是什么让我相信我添加的某些库正在搞砸一些事情 -
是的，它很奇怪。您是否将您的应用程序通过 proguard（如果您不这样做，是否会发生崩溃）？
-
是的，但我找到了问题所在。我的答案如下
