Question

我正在从实时数据库切换到Firestore，并且不断收到相同的错误：

无法解决：com.google.firebase：firebase-firestore：16.0.1

我在此站点上也曾研究过类似的问题，但仍无法解决此问题。这是我的应用gradle中的代码：

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

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.marykate.marykatefordefyp"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-core:16.0.1'
    //dependency for using firebase database
    implementation 'com.google.firebase:firebase-database:16.0.1'
    //dependency for email and password authentication
    implementation 'com.google.firebase:firebase-auth:16.0.1'
    //dependency for cloud storage
    implementation 'com.google.firebase:firebase-storage:16.0.1'
    implementation 'com.google.firebase:firebase-auth:16.0.1'
    implementation 'com.google.firebase:firebase-firestore:16.0.1'
}

我的项目gradle中的代码如下：


    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath 'com.google.gms:google-services:4.0.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

有人可以帮我吗？

要解决此问题，请更改以下代码行：

AutoItLibrary

到

implementation 'com.google.firebase:firebase-core:16.0.1'
//dependency for using firebase database
implementation 'com.google.firebase:firebase-database:16.0.1'
//dependency for email and password authentication
implementation 'com.google.firebase:firebase-auth:16.0.1'
//dependency for cloud storage
implementation 'com.google.firebase:firebase-storage:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.firebase:firebase-firestore:16.0.1'

请不要忘记在文件的最后一行添加

implementation 'com.google.firebase:firebase-core:16.0.6'
//dependency for using firebase database
implementation 'com.google.firebase:firebase-database:16.0.6'
//dependency for email and password authentication
implementation 'com.google.firebase:firebase-auth:16.1.0'
//dependency for cloud storage
implementation 'com.google.firebase:firebase-storage:16.0.5'
//implementation 'com.google.firebase:firebase-auth:16.0.1' //Removed
implementation 'com.google.firebase:firebase-firestore:18.0.0

Answer 2

使用failed to resolve firebase-firestore-16.0.1和Firebase Authentication时遇到Cloud Firestore问题。我将Gradle Dependencies更改为以下所列：-

implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-auth:16.2.0'
implementation 'com.google.firebase:firebase-firestore:18.1.0'

有时Gradle dependencies存在兼容性问题。请尝试使用最新版本。您可以在此处找到最新的Firebase gradle dependencies：latest Firebase gradle dependencies

Answer 3

我正在使用

if condition {
   do something
} else if condition2 {
   do something else
} else {
   do something else
}

，并且我收到了您在问题中报告的相同错误消息。它对我有用：

compile 'com.google.firebase:firebase-core:16.0.8'

无法解决：com.google.firebase：firebase-firestore：16.0.1
