如何使用最新的支持库(Getting failed to resolve error with support libr

问题描述

我已将我的 compileSdkVersion 更新为 26.这就是我的 gradle 文件现在的样子.

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).

我已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.两种情况都显示 Failed to resolve 错误.点击 Install Repository and sync project 会冻结 Android Studio 几秒钟，然后什么也没有发生.

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.

我错过了什么吗?

最新的Android支持版本库这里是26.0.2.

The latest Android support version library here is 26.0.2.

推荐答案

你应该在你的 App Level build.gradle 部分添加这个.

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

终于

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 高于 4.1 的版本，则必须使用:

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

allprojects {
      repositories {  
        google()

    }
}
