Question

我的环境：

React Native：0.50.4

Android Studio：3.1.1

Gradle：4.6

设备：Android模拟器（任何Android操作系统）

我正在更新我当前的反应原生应用以开始使用Firebase。我正在使用react-native-firebase包来集成它们，但我非常肯定这不是问题，因为我的问题出现在我开始处理之前。

以下是我的一些来源：

build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.1.2'
    }
}

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
            url 'https://maven.google.com'
        }
        google()
    }
}

“应用/ build.gradle`：

apply plugin: "com.android.application"

import com.android.build.OutputFile

project.ext.react = [
    entryFile: "index.js"
]

apply from: "../../node_modules/react-native/react.gradle"

            reset()

            universalApk false  // If true, also generate a universal APK
            include "armeabi-v7a", "x86"
        }
    }
    buildTypes {
        release {

            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }
    // applicationVariants are e.g. debug, release
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            // For each separate APK per architecture, set a unique version code as described here:
            // http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits
            def versionCodes = ["armeabi-v7a":1, "x86":2]
            def abi = output.getFilter(OutputFile.ABI)
            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
            }
        }
    }
}

dependencies {
    //compile(project(':react-native-firebase')) {
    //    transitive = false
    //}
    compile project(':react-native-config')
    compile project(':react-native-i18n')

    // firebase modules
    implementation "com.google.android.gms:play-services-base:12.0.1"
    implementation "com.google.firebase:firebase-core:12.0.1"

}

// Run this once to be able to run the application with BUCK

task copyDownloadableDepsToLibs(type: Copy) {
    from configurations.compile
    into 'libs'
}

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

一旦我构建并运行应用程序，我就会收到以下错误：

我确实尝试从12.0.1升级到15.0.0并让它构建并运行良好，但是当向Firebase发送消息时，它抱怨Google Play服务已过时。得到了这个错误：

W/GooglePlayServicesUtil: Google Play services out of date.  Requires 12451000 but found 12446024
W/FA: Service connection failed: ConnectionResult{statusCode=SERVICE_VERSION_UPDATE_REQUIRED, resolution=null, message=null}
V/FA: Processing queued up service tasks: 1
E/FA: Discarding data. Failed to send event to service

我是在Android P上运行的，所以我认为Google Play服务不会过时。我无法找到谷歌在哪里发布谷歌播放服务的版本，因为我有预感12.4.51.000尚不存在。

我试图找到答案，但没有人帮助过。一切都会有所帮助。谢谢！

Answer 1

我找到了解决方案。

将所有内容更新为依赖项中的15.0.0。是的，它将继续为您提供过时谷歌播放服务的错误，但没关系。
创建一个安装了Google Play商店的新模拟器（目前，我认为它只是Nexus 5和5X）。
打开模拟器并更新Google Play服务。您需要先打开Google Play并登录。完成后，您应该收到更新Google Play服务的通知。
完成更新后，您可以检查设置，看它是什么版本，以及它是否足够新（应该是什么）。
卸载应用并重新安装应用。它应该现在正在运作。
