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：> java.lang.NoSuchMethodError: No virtual method zzboy()Z in class> Lcom/google/firebase/FirebaseApp; or its super classes (declaration of> 'com.google.firebase.FirebaseApp' appears in> /data/app/com.bignerdranch.android.instagramclone-1/split_lib_dependencies_apk.apk)>                       at com.google.firebase.database.FirebaseDatabase.getInstance(Unknown Source)>                       at com.google.firebase.database.FirebaseDatabase.getInstance(Unknown Source)>                       at com.bignerdranch.android.instagramclone.Utils.FirebaseMethods.<init>(FirebaseMethods.java:57)>                       at com.bignerdranch.android.instagramclone.Share.NextActivity.onCreate(NextActivity.java:49)>                       at android.app.Activity.performCreate(Activity.java:6372)>                       at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1110)>                       at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2432)>                       at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2539)>                       at android.app.ActivityThread.access$900(ActivityThread.java:168)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 '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'
