Question

当我上次进行一些更改时，该应用程序运行良好。但是突然遇到了firebase的问题。

implementation project(':react-native-firebase')
    implementation 'com.android.support:support-v4:+'
    implementation 'com.google.firebase:firebase-core:16.0.9'
    implementation project(':react-native-device-info')
    implementation project(':react-native-vector-icons')
    implementation fileTree(dir: "libs", include: ["*.jar"])
    ..... other dependencies
    implementation 'com.google.firebase:firebase-messaging:16.1.0

出现错误

Answer 1

我在这里遇到了同样的问题，突然 android 停止工作。我正在使用 react-native 0.61.5。

您可以通过以下三种方法解决此问题：

第一种方法：（解决了我的问题） 在您的 android/build.gradle 上将此行添加到 ext 部分：

firebaseVersion = "21.1.0"

第二种方式：（也解决了我的问题） 如果第一种方法不起作用，也许你应该多做一点。在您的 android/buld.gradle 中：

  firebaseMessagingVersion = "21.1.0"
   buildToolsVersion = "29.0.2"
   firebaseCoreVersion = "17.0.0"
   firebaseVersion = "21.1.0"

在您的 android/app/build.gradle 上，添加：

implementation 'com.google.firebase:firebase-messaging:21.1.0'

第三种方式

您需要找到所有影响您的应用程序的 firebase 依赖项，注意使用与 firebase 相关的东西的 node_modules 依赖项。映射所有依赖项后，您需要在 android/build.gradle 和 android/app/build.gradle 上指定版本。

注意事项： 对不起我的英语，我试过了。

Answer 2

我遇到了这个问题，我发现 firebase-iid 在与 firebase-messaging 相同的版本上工作，但现在消息版本是 22.0.0，而 firebase-iid 的市长版本是 21.1.0，所以你有将依赖项与每个对应的版本分开。
