应用在Firebase数据库getinstance上崩溃

Question

在出现此错误之前，我将firebase-auth更新到版本16.0.2，以解决“程序类型已存在：com.google.android.gms.internal”错误。那会相关吗？

崩溃日志：

项目gradle：

buildscript {

    repositories {

        jcenter()

        google()

    }

    dependencies {

        classpath 'com.android.tools.build:gradle:3.1.2'

        // NOTE: Do not place your application dependencies here; they belong

        // in the individual module build.gradle files

        classpath 'com.google.gms:google-services:4.0.1'

    }

}

allprojects {

    repositories {

        jcenter()

        maven { url "https://jitpack.io" }

        google() // Google's Maven repository

    }

}

task clean(type: Delete) {

    delete rootProject.buildDir

}

Answer 1

您对firebase-database的依赖确实很老。尝试使用最新版本：implementation&nbsp;'com.google.firebase:firebase-database:16.0.1'此页面上列出了每个依赖项的最新版本。

Answer 2

我升级到4.2.0并成功了classpath 'com.google.gms:google-services:4.2.0'
