無法將EmojiCompat庫（com.android.support:support-emoji:26.1.0）添加到我的應用程序gradle

Question

我試圖在我的Android應用程序中使用EmojiCompat支持庫。當我添加-com.android.support:support-emoji:26.1.0 - 在應用程序的Gradle模塊的依賴關係，並嘗試同步它，我得到下面的錯誤 -

Error:(31, 13) Failed to resolve: com.android.support:support-emoji:26.1.0 

下面是我的build.gradle（

apply plugin: 'com.android.application' 
 

 
android { 
 
    compileSdkVersion 26 
 
    buildToolsVersion "26.0.2" 
 
    defaultConfig { 
 
     applicationId "example.example.com.emojis2"

// Top-level build file where you can add configuration options common to all sub-projects/modules.

allprojects { 
 
    repositories { 
 
     jcenter()

你應該在你項目級別build.gradle部分添加此。

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

DEMO

buildscript { 
    repositories { 
     jcenter() 
     // You need to add the following repository to download the new plugin. 
     maven { url 'https://maven.google.com' } 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.3' 

    } 
} 

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

FYI

要將它們添加到您的構建，需要首先包括Google's Maven repository在頂層build.gradle文件：

allprojects { 
    repositories { 
     google() 

     // If you're using a version of Gradle lower than 4.1, you must instead use: 
     // maven { 
     //  url 'https://maven.google.com' 
     // } 
     // An alternative URL is 'https://dl.google.com/dl/android/maven2/' 
    } 
}
