自动化构建
如何使用jenkins打包android和ios，并上传到蒲公英平台

1.全局变量的使用

ext {
    //全局变量控制，可在module中的build.gradle文件通过rootProject.ext.xxx开头来使用
    compileSdkVersion = 24
    buildToolsVersion = '24.0.3'
    supportVersion = '24.2.1'
    //主程序版本
    targetSdkVersion = 24
    minSdkVersion = 15
    versionCode = 1
    versionName = "v1.0.0"
    //library版本
    jjdxm_minSdkVersion = 9
    jjdxm_versionCode = 1
    jjdxm_versionName = "v1.0.0"
    jjdxm_v4 = 'com.android.support:support-v4:'+supportVersion
    jjdxm_v7 = 'com.android.support:appcompat-v7:'+supportVersion
    jjdxm_design = 'com.android.support:design:'+supportVersion
    jjdxm_cardview = 'com.android.support:cardview:'+supportVersion
    jjdxm_recyclerview = 'com.android.support:recyclerview-v7:'+supportVersion
}

module的build.gradle中调用全局变量中元素

apply plugin: 'com.android.library'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        minSdkVersion rootProject.ext.jjdxm_minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode rootProject.ext.jjdxm_versionCode
        versionName rootProject.ext.jjdxm_versionName

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

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'
    })
    testCompile 'junit:junit:4.12'
    compile rootProject.ext.jjdxm_v7
    compile rootProject.ext.jjdxm_design
}

　　

sdk版本设置规则

minSdkVersion <= targetSdkVersion <= compileSdkVersion   //(版本号<= 小于等于) 
minSdkVersion <= buildToolsVersion <= compileSdkVersion

2.配置打包用的签名

主要有接过分享或者授权登录功能的都应该知道，像微信或者微博的分享和授权登录提供sdk，只有在指定的签名下才能生效，而我们平时开发都习惯使用默认的androidkeystore打包签名，这个时候想要测试分享或者登录功能就需要手动去打包指定keystore的签名。非常影响开发效率，这个时候可以通过配置gradle，根据release或者是debug打包指定的签名。

项目根目录新建一个签名用到的密码管理文件signing.properties

signing.alias=dou361            #release
signing.password=dou361         #release
signing.jjdxm_alias=dou361      #debug
signing.jjdxm_password=dou361   #debug

在主程序build.gradle的apply plugin: ‘com.android.application’下面添加

Properties props = new Properties()
props.load(new FileInputStream(file(rootProject.file("signing.properties"))))

　　

在android{}节点里面添加

signingConfigs {
    release {
        keyAlias props['signing.alias']
        keyPassword props['signing.password']
        storeFile file(rootProject.file("debug.keystore"))
        storePassword props['signing.password']
    }

    debug {
        keyAlias props['signing.jjdxm_alias']
        keyPassword props['signing.jjdxm_password']
        storeFile file(rootProject.file("debug.keystore"))
        storePassword props['signing.jjdxm_password']
    }
}
buildTypes {
    debug {
        signingConfig signingConfigs.debug
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }

    release {
        signingConfig signingConfigs.release
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
