我正在学习Firebase,因为以下错误导致我们陷入困境:

Error:Failed to resolve: com.android.support:customtabs:25.4.0
Error:Failed to resolve: com.android.support.constraint:constraint-layout:1.1.0-beta1
Error:Failed to resolve: com.android.support:design:25.4.0
Error:Failed to resolve: com.android.support:support-core-utils:25.4.0
Error:Failed to resolve: com.android.support:cardview-v7:25.4.0

我的app / build.gradle文件中的依赖项是:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:design:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    //Firebase
    compile 'com.google.firebase:firebase-database:10.0.1'
    compile 'com.google.firebase:firebase-auth:11.0.2'
    compile 'com.firebaseui:firebase-ui-auth:2.1.1'
    testCompile 'junit:junit:4.12'    
}

以及app文件夹外的build.gradle文件

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

我想问一下这些错误是什么/是解决方案? 我一直在网上搜索这些错误的解决方案,但找不到可以解决我的问题的方法。

您需要更改以下代码行:

compile 'com.android.support.constraint:constraint-layout:1.0.2'

compile 'com.android.support.constraint:constraint-layout:1.0.1'

这两行有相同的版本:

compile 'com.google.firebase:firebase-database:11.0.1'
compile 'com.google.firebase:firebase-auth:11.0.1'

希望它有所帮助。

在我的程序中遇到同样的问题,我能够解决它。 根据Firebase网页上的available libraries,您应该使用最新的实时数据库相关性行: com.google.firebase:火力数据库:11.0.2
