我第一次尝试使用FCM（之前没有GCM经验）。所以，我只是从quickstart-android-push-notifs复制代码并设置仪表板
当我从仪表板发送消息时，应用程序强制关闭，这里是相关文件
app level build.gradle dependencies
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.+'
compile 'com.google.firebase:firebase-messaging:9.4.0'
}

出了什么问题？
答案 0 :(得分：4)
您应该在build.gradle
上插入此代码“编译”com.google.firebase：firebase-core：9.4.0'
我现在已经修好了。
答案 1 :(得分：3)
firebase-messaging和play-services必须是相同的版本：
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
...
compile 'com.google.firebase:firebase-messaging:10.2.0'
compile 'com.google.android.gms:play-services:10.2.0'
...
}
答案 2 :(得分：0)
您应该将compile 'com.google.firebase:firebase-core:9.6.1'添加到您的bulid.gradle
