android - 由于缺少依赖项，Twitter Fabric 无法在 Android Studio 中安装

Question

我正在使用 Fabric 设置一个 Cordova 项目以支持使用 Twitter 登录。我刚刚将 Fabric 插件安装到 Android Studio 中，但是当我同步 Gradle 文件时出现以下错误:

Information:Gradle tasks [:generateDebugSources, :generateDebugTestSources]

Android SDK 更新程序为我提供了支持库 21.0.3 而不是 21.0.0，正如来自 Fabric 的 Hemal 在此处所建议的:Android Twitter Fabric SDK conflict with support library

不过，我对其他那些库一无所知。有什么想法吗？

请遵循此代码示例以确保您的 build.gradle 文件类似:

    buildscript {
  repositories {
    jcenter()   // <- *add this
    maven { url 'https://maven.fabric.io/repo' }
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:0.13.3'
    // The Fabric Gradle plugin uses an open ended version to
    // react quickly to Android tooling updates
    classpath 'io.fabric.tools:gradle:1.+'
  }
}

apply plugin: 'com.android.application'   // <- *make sure this is the same

//Put Fabric plugin after Android plugin
apply plugin: 'io.fabric'

repositories {
    jcenter()   // <- *add this
    maven { url 'https://maven.fabric.io/repo' }
}

我有同样的问题，花了半天时间，直到打开推特的官方文档，看到了这个: https://dev.twitter.com/twitter-kit/android/integrate

Fabric 团队在 SO 和其他论坛上提供了太多无效的答案。这行得通。
