无法解决:com.android.support:appcompat-v7:26.0.0

问题描述

我在 Android Studio 中遇到了这个问题.

I am having this issue in Android studio.

Error:(22, 13) Failed to resolve: com.android.support:appcompat-v7:26.0.0
<a href="install.m2.repo">Install Repository and sync project</a><br><a href="openFile:C:/Users/username/AndroidStudioProjects/ElectroSave/app/build.gradle">Show in File</a><br><a href="open.dependency.in.project.structure">Show in Project Structure dialog</a>

这是我的 Gradle 代码:

This is my Gradle code:

apply plugin: 'com.android.application'

android {
       compileSdkVersion 26
      buildToolsVersion "25.0.2"
    defaultConfig {
    applicationId "com.example.noelly.myapplication"
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
}
   buildTypes {
      release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 
'proguard-rules.pro'




 dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     compile 'com.android.support:appcompat-v7:26.0.0'
}

推荐答案

要使用从版本 26.0.0 开始的支持库，您需要将 Google 的 Maven 存储库添加到项目的 build.gradle 文件中，如下所述:https://developer.android.com/topic/libraries/support-library/setup.html

To use support libraries starting from version 26.0.0 you need to add Google's Maven repository to your project's build.gradle file as described here: https://developer.android.com/topic/libraries/support-library/setup.html

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

对于 Android Studio 3.0.0 及更高版本:

For Android Studio 3.0.0 and above:

allprojects {
        repositories {
            jcenter()
            google()
        }
    }
