Android 中的打包配置在build.gradle文件中，下面對該文件的內容做一下記錄。

buildscript {repositories {jcenter()}dependencies {classpath 'com.android.tools.build:gradle:2.2.0'}
}

這里生命了倉庫的位置，依賴gradle的版本。

android{}

android {compileSdkVersion 22buildToolsVersion "23.0.2"defaultConfig {applicationId "com.insthub.*****"minSdkVersion 15targetSdkVersion 22versionCode 29versionName "2.0.7"}signingConfigs {debug {storeFile file('*******.keystore')storePassword '111111'keyAlias '*****'keyPassword '111111'}myConfig {storeFile file('farmlink.keystore')storePassword '111111'keyAlias 'farmlink'keyPassword '111111'}}lintOptions {warningsAsErrors falsecheckReleaseBuilds falseabortOnError false}compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1_8}buildTypes {release {minifyEnabled falsezipAlignEnabled falseshrinkResources falseproguardFiles   getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'signingConfig signingConfigs.myConfig}}sourceSets {main {res.srcDirs = ['src/main/res']}}

這里面的內容比較多，主要有配置android 支持版本、版本號、簽名配置、資源配置等內容。
關于簽名配置為了不再該文件顯示太多內容，可以使用配置文件的形式。

File propFile = File('signing.properties');
if(propFile.exists()){def Properties props = new Properties();props.load(new FileInputStream(propFile));if(props.containsKey('KEY_ALIAS') && props.containsKey('STORY_PASSWORD')&&props.containsKey('KEY_ALIAS') && props.containsKey('KEY_PASSWORD')){android.signingConfig.release.storeFile = file(props['STORE_FILE'])android.signingConfig.release.storeFile = file(props['STORE_PASSWORD'])android.signingConfig.release.storeFile = file(props['KEY_ALIAS'])android.signingConfig.release.storeFile = file(props['KEY_PASSWORD'])} else {android.buildTypes.release.signingConfig = null}
} else {android.buildTypes.release.signingConfig = null
}

signing.properties文件內容

STORE_FILE=*****.keystore
STORE_PASSWORD= *****
KEY_ALIAS=****
KEY_PASSWORD=****

在打包時可以給包命名：

applicationVariantsall {variant ->variant.outputs.each{ output ->def outputFile = output.outputFileif(outputFile != null && outputFile.name.endsWith('.apk')){File outputDirectory = new File(outputFile.parent);def fileName;if(variant.buildType.name == "release"){fileName = "****_v${defaultConfig.versionName}_$(releaseTime())}_${variant.productFlavors[0].name}.apk"} else {fileName = "farmlink_v${defaultConfig.versionName}_${releaseTime()}_debug.apk"}output.outputFile = new File(outputDirectory, fileName)}}
}

def releaseTime(){return new Date().format("yyyy-MM-dd_HH-mm",TimeZone.getTimeZone("GMT+8"))
}

下面就是渠道發布了

productFlavors{playStore{manifestPlaceholders = [UMENG_CHANNEL_VALUE:"playStore"]}
}

還可以這樣寫

productFlavors{wandoujia{}_360{}
}
