前言
当一个project下有多个module时,全局依赖参数可以统一起来,修改时只需修改一处就行了,比较方便。当然如果格式你看着不爽,可以不这样写,毕竟现在是社会主义社会嘛,选择自由。
配置
1.只想配置defaultConfig的情况和google系统的自带库
首先在项目的根build.gradle下配置ext
ext{
compileSdkVersion =25
buildToolsVersion= '25.0.2'
minSdkVersion = 16
targetSdkVersion = compileSdkVersion
versionCode =1
versionName ='1.0.0'
supportLibVersion = '25.3.1'
}
然后在app/build.gradle下修改defaultConfig
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
defaultConfig {
applicationId "com.xxx"
minSdkVersion rootProject.ext.minSdkVersion
targetSdkVersion rootProject.ext.targetSdkVersion
versionCode rootProject.ext.versionCode
versionName rootProject.ext.versionName
}
dependencies {
compile "com.android.support:design:$supportLibVersion"
compile "com.android.support:cardview-v7:$supportLibVersion"
}
2.想配置defaultConfig和所有依赖库的情况
在项目的根目录下创建config.gradle文件
ext{
android=[
applicationId:"com.fsp.aiyagirl",
compileSdkVersion :25,
buildToolsVersion :"25.0.2",
minSdkVersion : 16,
targetSdkVersion : 25,
versionCode : 1,
versionName :"1.0.0"
]
dependencies =[
"appcompat-v7" : "com.android.support:appcompat-v7:25.3.1",
"constraint" : "com.android.support.constraint:constraint-layout:1.0.2",
]
}
然后在根的build.gradle中引用
apply from: “config.gradle”
这样工程的所有module都能用这个文件的参数
最后在app/build.gradle中
android {
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
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile rootProject.ext.dependencies["appcompat-v7"]
compile rootProject.ext.dependencies["constraint"]
}
至此,配置工作已经全部结束,有不足之处可以提出来共同探讨。
