Question

我正在尝试从Firebase读取数据，但是由于某种原因我无法同步我的Gradle项目。

我去from pytest import fixture # added from paste.fixture import TestApp from app import app def test_index(test_app): r = test_app.get('/') assert r.status == 200 assert 'Hello, world!' in r @fixture() def test_app(): middleware = [] return TestApp(app.wsgifunc(*middleware))并添加了身份验证和实时数据库作为我在YouTube上推荐的视频。

但是之后我的Gradle项目同步继续失败。

我已经在Google上搜索了此问题，并试图更新我的版本，但没有成功。

我还在Tools -> Firebase文件的底部添加了com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true，但它表示这是不必要的合格引用。

这是一些代码。

build.gradle

build.gradle

build.gradle（模块：应用）

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.0.1'
        // 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
}

更新抱歉，我忘记添加错误消息了。

}
com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

我真的希望我可以同步文件。

谢谢！

Answer 1

请下次根据控制台或xlint提供有关错误的更多详细信息，以便我们评估问题。但是我已经遇到一个阻止同步的错误，您使用的库版本不同，会引起冲突。请注意，如果您使用一个版本的Firebase库，则必须使用相同版本的所有库。错误在这里：

implementation 'com.google.firebase:firebase-database:15.0.1' // 15.0.1????
implementation 'com.google.firebase:firebase-auth:16.0.3'  // 16.0.3???
implementation 'com.google.firebase:firebase-storage:16.0.1'  //16.0.1???

示例：

 implementation fileTree(dir: 'libs', include: ['*.jar'])


//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.google.firebase:firebase-core:16.0.3' //this is the same version
implementation 'com.google.firebase:firebase-auth:16.0.3' //than this
implementation 'com.google.firebase:firebase-database:16.0.3'
implementation 'com.google.firebase:firebase-storage:16.0.3'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:design:28.0.0'
implementation 'com.github.bumptech.glide:glide:4.9.0'
implementation 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.squareup.retrofit2:converter-gson:2.5.0'
implementation 'com.squareup.okhttp3:okhttp:3.4.2'
implementation 'com.squareup.okhttp3:logging-interceptor:3.9.1'
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'

Answer 2

只需替换此行

  implementation 'com.google.firebase:firebase-auth:16.0.1:15.0.0'
implementation 'com.google.firebase:firebase-database:16.0.1:15.0.0'

与

  implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
