Question

无法在我的 React Native 项目中解决此错误，该项目使用了 Firebase Cloud Messaging 模块 @react-native-firebase/messaging：

BUILD FAILED in 9s

error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup.

尝试过：

不同的 gradle 版本 6.9、7.0、7.0.1。
不同的 google-services 版本 4.3.5、4.3.6、4.3.7
在 build.gradle 应用的顶部和底部应用 google-services
不同的 gradle 插件 版本 4.1.3、4.2.0、4.2.1
删除并重新安装所有 node_modules
使用 gradlew clean 清理构建并在每次版本更改后重新构建

这是我的 npm 列表 输出：

我正在覆盖最新的 Firebase BOM 28.0.1。还尝试了默认的 @react-native-firebase 26.8.0 版本，然后应用程序在启动时崩溃，在构建或地铁时没有错误输出。应用在 android/app 上有 google-services.json 并在 firebase 中注册。目前使用 gradle 6.9、插件 4.1.3 和 google-services 4.3.5。

第一次在 index.js 上使用消息传递，监听后台推送消息，如 https://rnfirebase.io/messaging/usage 处的文档所述：

import {AppRegistry} from 'react-native';
import App from './App';
import {name as appName} from './app.json';
import messaging from '@react-native-firebase/messaging';

// Register background handler
messaging().setBackgroundMessageHandler(async (remoteMessage) => {
  console.log('Message handled in the background!', remoteMessage);
});

AppRegistry.registerComponent(appName, () => App);

稍后尝试获取设备令牌并调用云函数：

 var switchFunction = functions().httpsCallable(toggleFunctionName);
  messaging()
    .getToken()
    .then((token) => {
      switchFunction({
        organization: encodeURI(parsedLocalData.organizationName),
        user_email: encodeURI(parsedLocalData.userMai),
        device_token: token,
      })
        .then((result) => {
          // Read result of the Cloud Function.
          var sanitizedMessage = result.data.text;
          console.log('Firebase: ' + sanitizedMessage);
        })
        .catch((error) => {
          // Getting the Error details.
          console.log('Firebase error: ' + error);
        });
    });

将此添加到您的 app/build.gradle 下的依赖项：

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

这到 ext {} 下的顶级 build.gradle

firebaseMessagingVersion = "21.1.0"

此外，如果您还没有这样做，请在顶级 build.gradle 的依赖项下：

classpath 'com.google.gms:google-services:4.3.8'

最后，在 app/build.gradle 的顶部：

apply plugin: "com.android.application"
apply plugin: 'com.google.gms.google-services'
