出错时如何添加依赖性

Question

我正在尝试使用firebase制作聊天应用，我需要添加两个依赖项 compile 'com.android.support:design:26.1.0' compile 'com.firebaseui:firebase-ui:0.6.0'

我的基本compilesdkversion是

ompileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
    minSdkVersion 16
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

当我尝试添加两行代码依赖项段时，我得到了此错误

Failed to resolve: com.android.support:design:26.1.0

我该如何做对？谢谢...

Answer 1

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.constraint:constraint-layout:1.0.2'
    compile 'com.jakewharton:butterknife:8.8.1'
    compile 'com.android.support:design:25.3.1'
    testCompile 'junit:junit:4.12'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
    compile 'com.android.support:recyclerview-v7:25.3.1'
    compile 'com.android.support:cardview-v7:25.3.1'
}

and build.gradle（project）

allprojects {
    repositories {
        jcenter()
    }
}

希望这对您有帮助。
