所以我没有找到软件包的问题,​​我通过在android studio中对Firebase进行身份验证和同步解决了问题,此后,当我同步gradle时,我突然开始遇到这个问题。这是我的文件。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "APP NAME"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 42
        versionName '3.7'
    }

    dexOptions {

        jumboMode true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }

    productFlavors {
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.mcxiaoke.volley:library:1.0.19'
    implementation 'com.github.chrisbanes.photoview:library:1.2.3'
    implementation 'com.facebook.android:facebook-android-sdk:4.+'

    implementation 'com.google.firebase:firebase-core:16.0.0'
    implementation 'com.google.firebase:firebase-ads:15.0.1'
    implementation 'com.google.firebase:firebase-messaging:17.0.0'
    implementation 'com.google.android.gms:play-services-gcm:15.0.1'
    implementation 'com.google.android.gms:play-services-ads:15.0.1'
    implementation 'com.google.firebase:firebase-auth:11.6.0'
    compile 'com.google.firebase:firebase-core:16.0.0'
}

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


我无法弄清楚这里突然发生了什么错误,我分钟没有问题,只是与json文件/ firebase sync中的包名称有关的问题,然后在解决时弹出了。

最佳答案

此依赖关系违反了错误消息中的声明:

com.google.firebase:firebase-auth:11.6.0


您应该更新它:

com.google.firebase:firebase-auth:16.0.3
