Top Level Build.gradle:

buildscript {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'
    }
}
 
allprojects {
    repositories {
        maven { url "http://dl.bintray.com/populov/maven" }
        mavenCentral()
    }
}

App's build.gradle:

compile 'com.viewpagerindicator:library:2.4.1@aar'

To use Android-ViewPagerIndicator in Android Studio, you can’t download it from gradle. Instead, you must import the library as an “Existing Project” to your current one.

Follow these steps:

1.Download source code from GitHub.

2.In your Android Studio Project: File -> Project Structure -> add (+ symbol) -> Import Existing Project. Import just the folder called ”library”, not the entire project (leave the import options as Android Studio suggests).

3.If the "compileSdkVersion" specified in your build.gradle doesn’t match with the one specified in the Android-ViewPagerIndicator project, change the second one. The same apply with any other property, such as "minSdkVersion" or even the current support library.直接将App's build.gradle里面的android{}内容复制到新导入的模块的build.gradle中

4.Add Android-ViewPagerIndicator project as a dependency to your build.gradle module:

dependencies {
compile project(':library')
}
5.Sync project with gradle files.

使用 maven 导入

1.在最顶层的Build.gradle 中添加如下代码:

buildscript {
 
repositories {
 
maven { url "http://dl.bintray.com/populov/maven" }
 
mavenCentral()
 
}
 
dependencies {
 
classpath 'com.android.tools.build:gradle:0.12.+'
 }
 
}
 
allprojects {
 
repositories {
 
maven { url "http://dl.bintray.com/populov/maven" }
 
mavenCentral()
 
}
 
}

2.在自己的app’s的build.gradle添加

compile 'com.viewpagerindicator:library:2.4.1@aar'

以后想添加什么第三方的库，只需要在 http://search.maven.org/ 中搜索，然后添加在第2中就行了。

下载好源码，添加已经下载好的源码：

1.下载 source code

2.在你的 Android Studio Project: File -> Project Structure -> add (+ symbol) -> Import Existing Project. k只导入library”文件夹而不是整个工程 (leave the import options as Android Studio suggests).

3.按步骤设置（SDK 版本），然后next

4.在你app的build.gradle中添加依赖 dependencies { compile project ( ':library' ) }

注意：如果你项目中已经存在了support-v4，你需要删除，因为添加的 Android-ViewPagerIndicator 会包含这个库。在一个工程中不能有两个这样的库（工程会共用库中的这个jar）。如果 Android-ViewPagerIndicator Library 中的support-v4 不能满足你的要求，那只能用第2种方法，下载好后，把你要的support-v4替换Library文件夹中的，然后按步骤进行。
