我最近需要在我的项目中使用 Google GCM。来自其website据说:
Firebase Cloud Messaging (FCM) is the new version of GCM. It inherits the reliable and scalable GCM infrastructure, plus new features! See the FAQ to learn more. If you are integrating messaging in a new app, start with FCM. GCM users are strongly recommended to upgrade to FCM, in order to benefit from new FCM features today and in the future.
为了设置新的 Firebase 应用程序，我已按照 official website 中提供的说明进行操作。并做了以下事情:
- 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；
- 在顶级项目的 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' 编译 'com.google.firebase:firebase-messaging:9.0.0'并在最后一行添加: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:

任何解决此问题的帮助将不胜感激! 问候
最佳答案
好吧，经过一番挣扎，我找到了导致我问题的原因。基本上我有两个库模块——碰巧是我自己的——每个都导入不同版本的 com.android.support:appcompat-v7.* 和谷歌播放服务。让他们都导入相同的版本，问题就消失了。
