方法一：
方法二：
1.新建一个config.gradle文件，然后在build.gradle（最外层）中添加applyfrom:"config.gradle"（顶部）
2.设置版本号管理
defaultConfig{
applicationId rootProject.ext.android.applicationId
minSdkVersionrootProject.ext.android.minSdkVersion
targetSdkVersionrootProject.ext.android.targetSdkVersion
versionCode rootProject.ext.android.versionCode
versionName rootProject.ext.android.versionName
}
3.设置库
compilerootProject.ext.dependencies["support-v4"]
compilerootProject.ext.dependencies["butterknife"]
compilerootProject.ext.dependencies["glide"]
4.config.gradle中设置版本号和库
ext{
android = [compileSdkVersion:23,
buildToolsVersion:"23.0.2",
applicationId:"xxx.xxx.xxx",
minSdkVersion:14,
targetSdkVersion:22,
versionCode:2,
versionName:"1.1.0"]
dependencies = ["support-v4":'com.android.support:support-v4:23.1.1',
"appcompat-v7":'com.android.support:appcompat-v7:23.1.1',
"design":'com.android.support:design:23.1.1',
"butterknife":'com.jakewharton:butterknife:7.0.1',
"glide":'com.github.bumptech.glide:glide:3.6.1',
"glide-okhttp-integration":'com.github.bumptech.glide:okhttp-integration:1.3.1']
}
