Android Studio配置Gradle（包括signingConfigs、buildTypes和productFlavors等）

笔者目前使用的Gradle配置描述如下：

配置划分：

defaultConfig 默认配置

signingConfigs 签名信息配置

buildTypes

productFlavors

打包apk重命名

dependencies 依赖配置

详细配置：

1，defaultConfig 默认配置

defaultConfig {
//项目包名配置
applicationId "com.wildcreek.demo"
minSdkVersion 16
targetSdkVersion 19
versionCode 14
versionName "1.0.14"
}

2，signingConfigs 签名信息配置

signingConfigs {
release {//发布版本的签名配置
storeFile file(props['KEYSTORE_FILE'])
keyAlias props['KEY_ALIAS']
storePassword props['KEYSTORE_PWD']
keyPassword props['KEY_PWD']
}
debug {//调试版本的签名配置
storeFile file(props['DEBUG_KEYSTORE'])
keyAlias props['DEBUG_ALIAS']
storePassword props['DEBUG_KEYSTORE_PWD']
keyPassword props['DEBUG_KEY_PWD']
}
}

签名配置文件signing.properties：

KEYSTORE_FILE = release.keystore
KEY_ALIAS = wildcreek
KEYSTORE_PWD= xxx
KEY_PWD= xxx

DEBUG_KEYSTORE= debug.keystore
DEBUG_ALIAS= androiddebugkey
DEBUG_KEYSTORE_PWD= android
DEBUG_KEY_PWD= android

3， buildTypes

注意：
1 .minifyEnabled 会对代码进行混淆和压缩，shrinkResources 会对比R文件对无用资源进行删除
2.minifyEnabled 设置为true时shrinkResources 的设置才会生效

buildTypes {
release {
debuggable true
minifyEnabled true //启用Proguard
shrinkResources true //是否清理无用资源,依赖于minifyEnabled
zipAlignEnabled true //是否启用zipAlign压缩
signingConfig signingConfigs.release
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
debug {
debuggable true
minifyEnabled false  //不启用Proguard
shrinkResources false //是否清理无用资源,依赖于minifyEnabled
zipAlignEnabled false //是否启用zipAlign压缩
signingConfig signingConfigs.debug
}
}

4，productFlavors

自定义BuildConfig，工程编译后会生成BuildConfig类，该类会包含自定义字段。

假设工程包含beijing和shandong两个productFlavors，且拥有各自不同的服务器等配置信息。

productFlavors{
beijing{
buildConfigField("boolean", "IS_LOCAL", "false")
buildConfigField("String", "SERVER_NAME", "\"BJ\"")
buildConfigField("String", "SERVER_HOST", "\"http://xxx.xxx.xxx.xx:8080\"")
buildConfigField("String", "LOGIN_API", "\"login\"")
}
shandong{
buildConfigField("boolean", "IS_LOCAL", "false")
buildConfigField("String", "SERVER_NAME", "\"SD\"")
buildConfigField("String", "SERVER_HOST", "\"http://xxx.xxx.xxx.xx:8080\"")
buildConfigField("String", "LOGIN_API", "\"loginsd\"")
}
}

5，打包apk重命名

def releaseTime() {
return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
}
applicationVariants.all { variant ->
variant.outputs.each { output ->
def outputFile = output.outputFile
if (variant.buildType.name.equals('release')) {
def fileName = "Demo_v${defaultConfig.versionName}_${releaseTime()}_release.apk"
if(variant.flavorName.equals("beijing")){
fileName = "Demo_v${defaultConfig.versionName}_${releaseTime()}_beijing_release.apk"
}else if(variant.flavorName.equals("shandong")){
fileName = "Demo_v${defaultConfig.versionName}_${releaseTime()}_shandong_release.apk"
}
output.outputFile = new File(outputFile.parent, fileName)
}else if(variant.buildType.name.equals('debug')){
def fileName = "Demo_v${defaultConfig.versionName}_${releaseTime()}_debug.apk"
if(variant.flavorName.equals("beijing")){
fileName = "Demo_v${defaultConfig.versionName}_${releaseTime()}_beijing_debug.apk"
}else if(variant.flavorName.equals("shandong")){
fileName = "Demo_v${defaultConfig.versionName}_${releaseTime()}_shandong_debug.apk"
}
output.outputFile = new File(outputFile.parent, fileName)
}
}
}

6，dependencies 依赖配置

不同buildTypes 和productFlavors 依赖不同的jar的配置情况

dependencies {
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:support-v4:22.2.1'
compile 'com.google.code.gson:gson:2.2.1'
compile 'net.robinx:lib.blur:1.0.1'
debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5'
releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5'
compile fileTree(dir: 'libs', exclude:["*mtclib*.jar","*peerconnection*.jar"], include: "*.jar")
beijingCompile files("libs/mtclib_0908_bj.jar")
beijingCompile files("libs/libjingle_peerconnection_bj.jar")
shandongCompile files("libs/mtclib_170110_sd.jar")
shandongCompile files("libs/libjingle_peerconnection_sd.jar")
}
