android - 如何在 Nativescript 中使用 SDK Firebase (Android)

Question

我正在尝试在 Android 上原生使用 sdk Firebase，但是当我尝试使用以下方法初始化 Firebase 时:

com.google.firebase.FirebaseApp.initializeApp(utils.ad.getApplicationContext();

我收到这个错误

System.err: Error: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process *******. Make sure to call FirebaseApp.initializeApp(Context) first.

在我的 app.gradle 中:

dependencies {
   compile 'com.google.firebase:firebase-core:11.8.0'
   compile 'com.google.firebase:firebase-messaging:11.8.0'
   compile "com.google.android.gms:play-services-base:11.8.0"
}

可以帮我吗？

Answer 1

将规则添加到 platforms/android/build.gradle 文件，以包含 google-services 插件和 Google 的 Maven 存储库:

buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.1.1' // google-services plugin
    }
}

allprojects {
    repositories {
        // ...
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
    }
}

将 firebase 依赖项插入 App_Resources/Android/app.gradle:

dependencies {
  compile 'com.google.firebase:firebase-core:11.8.0'
  //compile 'com.google.firebase:firebase-messaging:11.8.0'
  //compile "com.google.android.gms:play-services-base:11.8.0"
  // ...
}

并在 App_Resources/Android/app.gradle 的末尾插入:

apply plugin: 'com.google.gms.google-services'

最后，如果你遇到错误:

> File google-services.json is missing. The Google Services Plugin cannot function without it.

手动复制 google-services.json 文件:

cp app/App_Resources/Android/google-services.json platforms/android/app/google-services.json
