Android --Android Stuido混淆签名打包

1、混淆文件 proguard-rules.pro

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in D:\Documents and Settings\Administrator\AppData\Local\Android\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# 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 *;
#}

#指定代码的压缩级别
-optimizationpasses
#包明不混合大小写
-dontusemixedcaseclassnames
#不去忽略非公共的库类
-dontskipnonpubliclibraryclasses
 #优化  不优化输入的类文件
-dontoptimize
 #预校验
-dontpreverify
 #混淆时是否记录日志
-verbose
 # 混淆时所采用的算法
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
#保护注解
-keepattributes *Annotation*
# 保持哪些类不被混淆
-keep public class * extends android.app.Fragment
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
#如果有引用v4包可以添加下面这行
-keep public class * extends android.support.v4.app.Fragment
#忽略警告
-ignorewarning
#####################记录生成的日志数据,gradle build时在本项目根目录输出################
#apk 包内所有 class 的内部结构
-dump class_files.txt
#未混淆的类和成员
-printseeds seeds.txt
#列出从 apk 中删除的代码
-printusage unused.txt
#混淆前后的映射
-printmapping mapping.txt

2、bulid.gradle(app)

    buildTypes {
        release {
            //不显示LOG
            buildConfigField "boolean","LOG_DEBUG","false"
            //混淆
            minifyEnabled true
            //Zipalign优化
            zipAlignEnabled true
            //加载默认混淆配置文件
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }
    }
