android studio 签名，打包，混淆，多渠道打包

一、在android studio 中有两种的方式可以进行打包

（1）第一种方式

build->generate signed apk  

而后选择要进行打包的项目，next  进行选择签名文件，填写密码 next 

在下面打包有两种选择，一种是release 一种是debug ，在debug的状态下是不会进行签名和混淆的，

只有选择release的状态下才会进行签名和混淆

点击finish即可签名打包成功

（2）第二种方式

在build variants 里面将要打包的项目进行选择  debug 或是 release 

而后在项目的build.gradle文件中进行配置文件位置，密码等

signingConfigs {        release {            storeFile file("签名文件位置")            keyAlias "  "            keyPassword " 密码 "            storePassword " 密码 "        }    }

而后直接进行run即可，生成的apk即使进行过签名的apk文件。

生成的apk文件在：android studio工程的存储路径下 app/build/outputs/apk 中

二、在android studio中进行混淆

在eclipse中的是  proguard.cfg 文件 而在android studio中使用的是proguard-rules.pro ，不过直接拿过来用也是可以的

只要在build.gradle里面进行配置下即可，如下是在build.gradle中的配置

buildTypes {        debug{//测试下的配置            minifyEnabled false            shrinkResources false            signingConfig  signingConfigs.release        }        release {//正式的配置            minifyEnabled true  // false表示不混淆，true表示混淆            shrinkResources true //移除无用的resource文件            //如果用eclipse里面的proguard.cfg，直接替换 proguard-rules.pro 即可            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            signingConfig  signingConfigs.release        }    }

以下是整个的build.gradle的配置文件

apply plugin: 'com.android.application'android {    compileSdkVersion 21    buildToolsVersion '21.1.2'    defaultConfig {        applicationId "com.**.**"        minSdkVersion 8        targetSdkVersion 21        versionCode 1        versionName "1.0"    }    packagingOptions {        exclude 'META-INF/DEPENDENCIES'        exclude 'META-INF/LICENSE.txt'        exclude 'META-INF/license.txt'        exclude 'META-INF/NOTICE.txt'        exclude 'META-INF/notice.txt'        exclude 'META-INF/ASL2.0'        exclude 'META-INF/NOTICE'        exclude 'META-INF/LICENSE'        exclude '!META-INF/MANIFEST.MF'        exclude 'META-INF/MANIFEST.MF'    }    sourceSets.main {        jniLibs.srcDirs = ['libs']    }    productFlavors {    }    /**     * 签名设置     */    signingConfigs {        release {            storeFile file("**")            keyAlias "**"            keyPassword "**"            storePassword "**"        }    }    buildTypes {        debug{            minifyEnabled false            shrinkResources false            signingConfig  signingConfigs.release        }        release {            minifyEnabled true            shrinkResources true            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            signingConfig  signingConfigs.release        }    }}dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    compile 'com.umeng.analytics:analytics:latest.integration'    compile files('libs/httpclient-android-4.3.3.jar')    compile files('libs/httpmime-4.3.5.jar')    compile files('libs/jpush-sdk-release1.7.3.jar')    compile files('libs/mframework.jar')    compile files('libs/nineoldandroids-2.4.0.jar')    compile files('libs/pinyin4j-2.5.0.jar')    compile files('libs/ShareSDK-Core-2.5.9.jar')    compile files('libs/ShareSDK-QZone-2.5.9.jar')    compile files('libs/ShareSDK-SinaWeibo-2.5.9.jar')    compile files('libs/ShareSDK-TencentWeibo-2.5.9.jar')    compile files('libs/ShareSDK-Wechat-2.5.9.jar')    compile files('libs/ShareSDK-Wechat-Core-2.5.9.jar')    compile files('libs/ShareSDK-Wechat-Favorite-2.5.9.jar')    compile files('libs/ShareSDK-Wechat-Moments-2.5.9.jar')    compile files('libs/umeng-analytics-v5.6.4.jar')    compile files('libs/swipemenulistview.jar')    compile files('libs/xstream-1.4.7.jar')    compile project(':**')    compile project(':wheel')}

在使用友盟统计的时候，只需要在dependencies中添加

compile 'com.umeng.analytics:analytics:latest.integration'

不需要在lib中添加jar包，要不会有 zip无法打开，或是包重复的错误

以下是混淆文件  proguard-rules.pro

配置完后，之间像，签名打包进行打包即可

三、多渠道打包

在项目的 androidmanifest.xml 中添加

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

而后在项目的build.gradle中添加即可

//多渠道打包productFlavors {    LianXiang {}    Baidu {}    AnZhi{}    F360{}    xiaomi {}    MeiZu{}    WanDouJia{}    QQYingYongBao{}    productFlavors.all { flavor ->        flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]    }}

通过 build->generate signed apk  进行打包，即可得到多个渠道的apk包
