Android笔记(七)：app混淆签名打包过程记录

1.配置模块下的build.gradle文件：
apply plugin: 'com.android.application'

def releaseTime() {
return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
}

android {
compileSdkVersion 26
defaultConfig {
applicationId "com.xx.xxxx"
minSdkVersion 19
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {

//Zipalign优化
zipAlignEnabled true

minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}
}
applicationVariants.all { variant ->
variant.outputs.all {
// 输出apk名称为app_v1.0_2018-xx-xx_xxxx.apk
def fileName = "app_${defaultConfig.versionName}_${releaseTime()}.apk"
outputFileName = fileName

}
}

sourceSets {
main {
jniLibs.srcDir 'libs'
jni.srcDirs = []
}
}
}

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
compile 'org.greenrobot:eventbus:3.1.1'
compile 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
implementation files('libs/tbs_sdk_thirdapp_v3.5.0.1004_43500.jar')
}

android studio3.0 设置打包的apk文件名要在android{}代码块内如上所示，与2.x版本不同。
2.编写混淆配置文件proguard-rules.pro：
# Add project specific ProGuard rules here.
# You can control the set of applied configuration files using the
# proguardFiles setting in build.gradle.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile
# 代码混淆压缩比，在0~7之间，默认为5，一般不做修改
-optimizationpasses 5

# 混合时不使用大小写混合，混合后的类名为小写
-dontusemixedcaseclassnames

# 指定不去忽略非公共库的类
-dontskipnonpubliclibraryclasses

# 这句话能够使我们的项目混淆后产生映射文件
# 包含有类名->混淆后类名的映射关系
-verbose

# 指定不去忽略非公共库的类成员
-dontskipnonpubliclibraryclassmembers

# 不做预校验，preverify是proguard的四个步骤之一，Android不需要preverify，去掉这一步能够加快混淆速度。
-dontpreverify

# 保留Anno
4000
tation不混淆
-keepattributes *Annotation*,InnerClasses

# 避免混淆泛型
-keepattributes Signature

# 抛出异常时保留代码行号
-keepattributes SourceFile,LineNumberTable

# 指定混淆是采用的算法，后面的参数是一个过滤器
# 这个过滤器是谷歌推荐的算法，一般不做更改
-optimizations !code/simplification/cast,!field/*,!class/merging/*

其中有忽略内嵌类，第三方butterknife，eventbus，百度定位sdk，百度语音识别sdk，TBS X5 WebView的混淆规则。3.点击Build->Generate Signed APK；填写密钥库信息；下一步是生成apk的存放位置，Signature Versions勾选V1+V2，Finish。在app\build\outputs\mapping\release目录下可以里面有混淆前后文件的映射信息等文本文件，用于调试bug。
