最近在导入一些开源项目的时候，发现配置文件的写法和自己平时写的不一样，平时是这样写的。
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.example.hecun.myapplication"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
........
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.1'
compile 'com.android.support:design:23.2.1'
compile 'com.nineoldandroids:library:2.4.0'
}
其实还有另外一种写法，有些项目中会这样写。
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'])
compile project(":libraries:headsupcompat")
compile project(":libraries:smooth-app-bar-layout")
compile rootProject.ext.dependencies["design"]
compile rootProject.ext.dependencies["appcompat-v7"]
compile rootProject.ext.dependencies["recyclerview-v7"]
compile rootProject.ext.dependencies["picasso"]
compile rootProject.ext.dependencies["numberprogressbar"]
compile rootProject.ext.dependencies["photoview"]
compile rootProject.ext.dependencies["umeng-analytics"]
compile rootProject.ext.dependencies["retrofit"]
compile rootProject.ext.dependencies["rxandroid"]
compile rootProject.ext.dependencies["okhttp-urlconnection"]
compile rootProject.ext.dependencies["okhttp"]
compile rootProject.ext.dependencies["butterknife"]
compile rootProject.ext.dependencies["otto"]
compile rootProject.ext.dependencies["glide"]
}
可以看到和我们写的不一样，应该是引用了某个地方的东西，我们去看看
我们打开这个文件
ext {
android = [compileSdkVersion: 22,
buildToolsVersion: "22.0.1",
applicationId : "me.drakeet.meizhi",
minSdkVersion : 14,
targetSdkVersion : 22,
versionCode : 359,
versionName : "2.5.9"]
dependencies = ["appcompat-v7" : "com.android.support:appcompat-v7:22.2.1",
"design" : "com.android.support:design:22.2.1",
"recyclerview-v7" : "com.android.support:recyclerview-v7:22.2.1",
"nineoldandroids" : "com.nineoldandroids:library:2.4.0",
"picasso" : "com.squareup.picasso:picasso:2.5.2",
"photoview" : "com.github.chrisbanes.photoview:library:1.2.3",
"numberprogressbar" : "com.daimajia.numberprogressbar:library:1.2@aar",
"umeng-analytics" : "com.umeng.analytics:analytics:latest.integration",
"retrofit" : "com.squareup.retrofit:retrofit:1.9.0",
"rxandroid" : "io.reactivex:rxandroid:1.0.0",
"okhttp-urlconnection": "com.squareup.okhttp:okhttp-urlconnection:2.0.0",
"okhttp" : "com.squareup.okhttp:okhttp:2.0.0",
"butterknife" : "com.jakewharton:butterknife:7.0.1",
"otto" : "com.squareup:otto:1.3.8",
"glide" : "com.github.bumptech.glide:glide:3.6.1"]
}
注意，这时候需要在跟目录build.gradle中添加下面一句话
apply from: "config.gradle"
