一个project会有多个app，不同module中都要配置compileSdkVersion、buildToolsVersion等变量值，这时候每个app中的compile工程如果不能统一，在以后升级里会很麻烦，所以我们要把这些公共的配置项称为共享变量。
步骤：
1、在项目的根目录下定义了一个build_config.gradle的配置文
config.gradle：
configField 数组中定义 测试环境和正式环境的地址还有API版本和apk的名字
ext {
configField = [
ServerAddress_release : "\"https://s.xxxx.com/\"",
// ServerAddress_release : "\"http://inflexion.xxxx.com/\"",
// ServerAddress_debug : "\"https://s.xxxx.com/\"",
ServerAddress_debug : "\"http://inflexion.xxxx.com/\"",
APIVersionName : "\"ver\"",
APIVersionCode : "\"2.36\"",
APKVersionName_release : "车店长Boss_正式版_",
APKVersionName_debug : "车店长Boss_测试版_",
]
android = [
compileSdkVersion : 25,
buildToolsVersion : "26.0.2",
minSdkVersion : 20,
targetSdkVersion : 25,
versionCode : 15,
versionName : "3.13.0"
]
versions数组，用来存放compileSdkVersion、versionCode、versionName等数据：
version = [
// androidSupportSdkVersion: "23.1.1",
androidSupportSdkVersion: "25.0.0",
retrofitSdkVersion : "2.3.0",
dagger2SdkVersion : "2.11",
glideSdkVersion : "4.0.0",
butterknifeSdkVersion : "8.7.0",
rxlifecycleSdkVersion : "1.0",
rxlifecycle2SdkVersion : "2.1.0",
espressoSdkVersion : "2.2.2",
canarySdkVersion : "1.5.1",
rxbindingSdkVersion : "0.4.0"
]
dependencies数组，用来存放第三发依赖的地址；
dependencies = [
//support
"appcompat-v7" : "com.android.support:appcompat-v7:${version["androidSupportSdkVersion"]}",
"design" : "com.android.support:design:${version["androidSupportSdkVersion"]}",

}
2、在项目根目录的build.gradle中直接引入我们配置的build_config.gradle配置文件。
apply from: “config.gradle”
3、当我们编写完自定义的gradle files，在Android Studio中实时保持同步
4、使用的时候：在各个module的build.gradle里面使用
android {
compileSdkVersion rootProject.ext.android["compileSdkVersion"]
buildToolsVersion '26.0.2'
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
defaultConfig {
applicationId "com.icarzoo"
minSdkVersion rootProject.ext.android["minSdkVersion"]
targetSdkVersion rootProject.ext.android["targetSdkVersion"]
versionCode rootProject.ext.android["versionCode"]
versionName rootProject.ext.android["versionName"]
...
}
buildTypes {
release {
buildConfigField('boolean', 'isShowLoaCat', "false")
buildConfigField('String', 'APIVersionName', rootProject.ext.configField["APIVersionName"])
buildConfigField('String', 'APIVersionCode', rootProject.ext.configField["APIVersionCode"])
buildConfigField('String', 'ServerAddress', rootProject.ext.configField["ServerAddress_release"])
signingConfig signingConfigs.release
debuggable true
minifyEnabled true
zipAlignEnabled true
pseudoLocalesEnabled false //默认false,是否支持本地化整理
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
buildConfigField('boolean', 'isShowLoaCat', "true")
buildConfigField('String', 'APIVersionCode', rootProject.ext.configField["APIVersionCode"])
buildConfigField('String', 'APIVersionName', rootProject.ext.configField["APIVersionName"])
buildConfigField('String', 'ServerAddress', rootProject.ext.configField["ServerAddress_debug"])
//signingConfig signingConfigs.release
debuggable true
minifyEnabled false
zipAlignEnabled true
pseudoLocalesEnabled false //默认false,是否支持本地化整理
}
}
applicationVariants.all { variant ->
variant.outputs.all { output ->
// def outputFile = output.outputFile
// def outputFile = outputFileName
def fileName
if (variant.buildType.name.equals('release')) {
fileName = "${rootProject.ext.configField["APKVersionName_release"]}.apk"
} else if (variant.buildType.name.equals('debug')) {
fileName = "${rootProject.ext.configField["APKVersionName_debug"]}.apk"
}
// ${project.projectDir}/../outputs/apks/+ variant.name
outputFileName = new File("", fileName)
// output.outputFile = new File(outputFile.parent, fileName)
// outputFileName = new File(outputFile.parent, fileName)
}
}
dependencies {
testCompile 'junit:junit:4.12'
// 所需的support包
compile rootProject.ext.dependencies["multidex"]
compile rootProject.ext.dependencies["appcompat-v7"]
compile rootProject.ext.dependencies["annotations"]
compile rootProject.ext.dependencies["recyclerview-v7"]
compile rootProject.ext.dependencies["design"]
compile rootProject.ext.dependencies["support-v4"]
compile rootProject.ext.dependencies["gridlayout-v7"]
compile rootProject.ext.dependencies["cardview-v7"]
// Rxbinding
compile rootProject.ext.dependencies["rxbinding"]
compile rootProject.ext.dependencies["rxbinding-design"]
compile rootProject.ext.dependencies["rxbinding-kotlin"]
compile rootProject.ext.dependencies["rxbinding-support-v4"]
compile rootProject.ext.dependencies["rxbinding-support-v7"]
...
}
buildConfigField使用的时候 这样调用：
public class NetWorkURLBean {
/**
* 访问服务端的地址
*/
public static String ADDRESS = BuildConfig.ServerAddress + "api/";
public static String ADDRESS_2 = BuildConfig.ServerAddress;
/**
* 登录
*/
public static final String STAFF = ADDRESS + "store_staff/staff_user/lunch_login";
