Android Studio 使用config.gradle 管理依赖库
在project根目录下创建一个config.gradle，将一些配置信息及第三方依赖统一管理。
ext {
android = [
compileSdkVersion : 25,
buildToolsVersion : "26.0.2",
applicationId : "com.xxxx.xxxxx",
minSdkVersion : 19,
targetSdkVersion : 25,
versionCode : 1,
versionName : "1.0"
]
dependVersion = [
support: "25.3.1"
]
dependencies = [

}然后在项目project的build.gradle文件中引入
apply from: "config.gradle"在app（或者其他module）目录下的build.gradle文件中使用如下配置:
compileSdkVersion rootProject.ext.android.compileSdkVersion
buildToolsVersion rootProject.ext.android.buildToolsVersion
defaultConfig {
applicationId rootProject.ext.android.applicationId
minSdkVersion rootProject.ext.android.minSdkVersion
targetSdkVersion rootProject.ext.android.targetSdkVersion
versionCode rootProject.ext.android.versionCode
versionName rootProject.ext.android.versionName
}
compile rootProject.ext.dependencies["design"]
compile rootProject.ext.dependencies["appcompat-v7"]
compile rootProject.ext.dependencies["recyclerview-v7"]
compile rootProject.ext.dependencies["picasso"]使用这种方式的好处是当Android Support Repository有更新时，方便管理依赖包的版本号
