android - FirebaseInitProvider : FirebaseApp initialization unsuccessful

Question

我们关注了Add Firebase to your Android Project但我们在 Firebase 控制台中看不到应用接收数据。
当我们启动应用程序时，日志显示:

FirebaseInitProvider: FirebaseApp initialization unsuccessful

这是什么意思？我们做错了什么？
我在文档中找不到此错误，在 StackOverflow 中也找不到。

Answer 1

What does this mean? What are we doing wrong?

假设身份验证没有成功。

a) project 级别的 buildscript repositories 和 dependencies build.gradle:

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        
        // Android Gradle Plugin
        classpath "com.android.tools.build:gradle:3.3.2"

        // Google Services Plugin
        classpath "com.google.gms:google-services:4.2.0"
    }
}

b) module 级别 app/build.gradle 的 dependencies(Android Intel x86 镜像可能仍具有以前版本的安装的 Google Play 服务，例如 10.2.0 在当前的 x86 模拟器上运行，而例如 11.8.0 在我的物理上运行 ARM设备)。引用 play-services 和 firebase-core 将包含它们的 all 模块，除非将它们排除在外。 更新:现在必须单独引用所有库。引用 com.google.android.gms:play-services 和 com.google.firebase:firebase-core 不再起作用，因为 15.0.0.

android {
    ...
    buildTypes {
        debug {
            // suffixing the package name for debug builds,
            // in order to partially mute the crash-reporting
            // is an *optional* configuration (see below):
            applicationIdSuffix ".debug"
        }
    }
}

dependencies {

    // Google Play Services
    // https://developers.google.com/android/guides/releases
    implementation "com.google.android.gms:play-services-base:15.0.1"
    implementation "com.google.android.gms:play-services-auth:16.0.0"
    implementation "com.google.android.gms:play-services-identity:15.0.1"

    // Google Firebase
    // https://firebase.google.com/support/release-notes/android
    implementation "com.google.firebase:firebase-core:16.0.1"
    implementation "com.google.firebase:firebase-auth:16.0.3"
    implementation "com.google.firebase:firebase-config:16.0.0"
    implementation "com.google.firebase:firebase-storage:16.0.1"
    implementation "com.google.firebase:firebase-database:16.0.1"
    implementation "com.google.firebase:firebase-messaging:17.3.0"
    implementation "com.google.firebase:firebase-appindexing:16.0.1"
    implementation "com.google.firebase:firebase-functions:16.1.0"
    implementation "com.google.firebase:firebase-invites:16.0.1"
    // implementation "com.google.firebase:firebase-crash:16.0.1"
    implementation "com.google.firebase:firebase-ads:15.0.1"
    implementation "com.google.firebase:firebase-firestore:17.0.4"
    implementation "com.google.firebase:firebase-perf:16.0.0"

    // the inapp messaging may cause dependency conflicts: 
    // implementation "com.google.firebase:firebase-inappmessaging:17.0.0"
    // implementation "com.google.firebase:firebase-inappmessaging-display:17.0.0"
}

c) mobile/build.gradle 的底线应该是:

// apply the Google Services Plugin
apply plugin: "com.google.gms.google-services"

d) 确保在 app/google-services.json 中提供(下载的)凭据；在 Firebase 控制台上，必须添加 both SHA1(或 SHA256)散列，调试 和 发布 key ，以使两个版本都能正确进行身份验证；一旦全部匹配，它应该报告:

I/FirebaseInitProvider: FirebaseApp initialization successful

这一切都有很好的记录，请参阅 Setup Google Play Services , Firebase Quickstart或 Crash Reporting ;虽然我发现 Firebase 博客上的这篇文章非常有用:Organizing your Firebase-enabled Android app builds ，因为它解释了如何部分静音崩溃报告。 release notes始终宣布更新和更改。
