从Google我们网站下载插件并成功运行解析器后，我已经实现了Firebase Analytics和Firebase Messaging。 问题是在构建后，当App第一次运行时它崩溃并显示以下错误，但是从第二次开始，该应用程序不会崩溃 这是日志

尝试将此行添加到gradle：
implementation 'com.google.firebase:firebase-messaging:+'
我认为它应该到文档末尾，如果不能在其他类似地方尝试的话：
dependencies {
implementation 'com.google.firebase:firebase-messaging:+'
implementation fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:multidex:1.0.1'
**DEPS**}
或者在这里：
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
implementation 'com.google.firebase:firebase-messaging:+'
**BUILD_SCRIPT_DEPS**}
}

几天前，我遇到了同样的问题，并且通过将所有Firebase库更新为最新版本来解决了该问题。似乎它们之间的依赖关系可能是版本冲突。 您可以找到Firebase库here
