Question

运行该应用程序时出现此错误。我已经为Firebase身份验证设置了所有设置，但我没有使用电话身份验证，因此此错误似乎有点奇怪。
这是我的android / build.gradle文件。

    buildscript {
    repositories {
            maven {
                url 'https://maven.google.com/'
                name 'Google'
            }
            jcenter()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:2.2.3'
            classpath 'com.google.gms:google-services:4.0.1'    
        }    
    }

这是我的android / app / build.gradle文件

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        applicationId "com.plastinction"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
    splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk false  // If true, also generate a universal APK
            include "armeabi-v7a", "x86"
        }
    }
    buildTypes {
        release {
            minifyEnabled enableProguardInReleaseBuilds
            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-image-picker')
    compile project(':react-native-vector-icons')
    compile project(':rn-fetch-blob')
    compile project(':react-native-pdf')
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    compile 'com.android.support:multidex:1.0.1'
    compile "com.facebook.react:react-native:+"  // From node_modules
    compile 'com.google.firebase:firebase-core:16.0.1'
    compile 'com.google.firebase:firebase-auth:11.8.0'

}

这是我的Package.json

    "firebase": "^5.5.8",
    "native-base": "^2.7.1",
    "react": "16.3.1",
    "react-native": "0.55.4",

  }

我的构建成功，但是在加载应用程序时发生此错误，有人可以帮忙吗？

我通过将firebase依赖项更新到最新版本解决了该问题。只需添加此内容而不是您的Firebase依赖项：

compile 'com.google.firebase:firebase-core:16.0.4'
compile 'com.google.firebase:firebase-auth:16.0.5'
compile 'com.google.firebase:firebase-database:16.0.5'

“ NativeModules”中的Java异常java.lang.NoClassFoundError：com.google.firebase.auth.PhoneAuthCredentials
