android studio多渠道打包+混淆配置

1.android多渠道打包

在manifest.xml文件中配置渠道号

        <meta-data            android:name="UMENG_CHANNEL"            android:value="${UMENG_CHANNEL_VALUE}"/>

在build.gradle下配置

// 打包渠道    productFlavors {        xiaomi {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "xiaomi"]        }        qh360 {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "qh360"]        }        baidu {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"]        }    }

我的项目的build.gradle配置

apply plugin: 'com.android.application'def releaseTime() {    return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))}android {    compileSdkVersion 25    buildToolsVersion "25.0.3"    defaultConfig {        applicationId "com.icloud.game"        minSdkVersion 16        targetSdkVersion 25        versionCode 1        versionName "1.0"        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"    }     //签名    signingConfigs {        debug {        }        release {// 自己的签名文件 ../chao.jks            storeFile file("E:/keystore/chao.jks")            storePassword "123456"            keyAlias "key0"            keyPassword "123456"        }    }     buildTypes {        debug {            // 显示Log            buildConfigField "boolean", "LOG_DEBUG", "true"            versionNameSuffix "-debug"            minifyEnabled false            zipAlignEnabled false            shrinkResources false            signingConfig signingConfigs.debug        }        release {            // 不显示Log            buildConfigField "boolean", "LOG_DEBUG", "false"            //混淆            minifyEnabled true            //Zipalign优化            zipAlignEnabled true            // 移除无用的resource文件            shrinkResources true            //前一部分代表系统默认的android程序的混淆文件，该文件已经包含了基本的混淆声明，后一个文件是自己的定义混淆文件            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            //签名            signingConfig signingConfigs.release            applicationVariants.all { variant ->                variant.outputs.each { output ->                    def outputFile = output.outputFile                    if (outputFile != null && outputFile.name.endsWith('.apk')) {                        // 输出apk名称为app_v1.0_2015-xx-xx_xxxx.apk                        //def fileName = "app_v${defaultConfig.versionName}_${releaseTime()}.apk"                        def fileName = "app_v${defaultConfig.versionName}_${variant.productFlavors[0].name}.apk"                        output.outputFile = new File(outputFile.parent, fileName)                    }                }            }        }    }// 打包渠道    productFlavors {        xiaomi {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "xiaomi"]        }        qh360 {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "qh360"]        }        baidu {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"]        }    }}  dependencies {    compile fileTree(include: ['*.jar'], dir: 'libs')    compile 'com.android.support.constraint:constraint-layout:1.0.1'    compile 'com.squareup.okhttp3:okhttp:3.8.1'    compile 'com.android.support:support-v4:25.3.1'}

对于混淆的语法，例如引入的第三方jar包可以使用以下语法：

-keep class com.UCMobile.PayPlugin.* {*;}

表示将包com.UCMobile.PayPlugin.*；的全部类都不混淆

-keep class com.unionpay.** {*;}

表示包com.unionpay的子包以及子包中的类全都不混淆

在命令行中打包

gradlew assembleReleasegradlew assemblexiaomiRelease

第一个语句将会把所有配置的渠道都生成渠道包
第二个语句将会只生成小米的渠道包

签名密码写在gradle中不安全，如果需要在命令行中输入签名密码：

signingConfigs { //gradle assembleRelease      myConfig {          storeFile file("stone.keystore")          storePassword System.console().readLine("\nKeystore password: ")          keyAlias "stone"          keyPassword System.console().readLine("\nKey password: ")      }  }
