如何使用最新的支持库(支持库26.0.2和compileSDKVersion 26未能解决错误)? [英] How do I use the latest support library (Getting failed to resolve error with support library 26.0.2 and compileSDKVersion 26)?

问题描述

我已经将compileSdkVersion更新为26.这就是我的gradle文件的外观.

I have updated my compileSdkVersion to 26. This is how my gradle file looks now.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId ##############
        minSdkVersion 21
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    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.android.support:recyclerview-v7:25.3.1'
    compile 'com.android.support:cardview-v7:25.3.1'
    testCompile 'junit:junit:4.12'
}

可以预见的是，我在支持库(25.3.1)和CompileSdkVersion(26)的版本中收到关于不匹配(?)的警告.

Predictably, I get warnings for the mismatch(?) in the versions of support library (25.3.1) and the CompileSdkVersion (26).

我尝试将支持库版本更新为以下版本:

I have tried to update the support library version to the below versions:

• 编译'com.android.support:appcompat-v7:26.0.0'
• 编译'com.android.support:appcompat-v7:26.0.2'

问题

他们都没有工作.两种情况均显示Failed to resolve错误.点击Install Repository and sync project会将Android Studio冻结几秒钟，并且没有其他反应.

None of them worked. Both cases show Failed to resolve errors. Clicking on Install Repository and sync project freezes Android Studio for a couple of seconds and nothing else happens.

我想念什么吗?

最新的Android支持版本库此处是26.0.2.

The latest Android support version library here is 26.0.2.

推荐答案

您应将其添加到 App Level build.gradle 部分.

You should add this in your App Level build.gradle section.

最后

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

然后 Clean-Rebuild 和 Run .

Then Clean-Rebuild and Run .

仅供参考

如果您使用的是 Gradle higher than 4.1 版本，则必须使用:

If you're using a version of Gradle higher than 4.1, you must use :

allprojects {
      repositories {  
        google()

    }
}
