android代码混淆

步骤：
1，项目下的peroject.properties文件放开画线这行注释

2，放开之后更改成如下图

3，正如现在看到的有一个文件proguard-android.text没有，得添加文件内容如下

# This is a configuration file for ProGuard.# http://proguard.sourceforge.net/index.html#manual/usage.html-dontusemixedcaseclassnames-dontskipnonpubliclibraryclasses-ignorewarnings-verbose# Optimization is turned off by default. Dex does not like code run# through the ProGuard optimize and preverify steps (and performs some# of these optimizations on its own).-dontoptimize-dontpreverify# Note that if you want to enable optimization, you cannot just# include optimization flags in your own project configuration file;# instead you will need to point to the# "proguard-android-optimize.txt" file instead of this one from your# project.properties file.-keepattributes *Annotation*-keep public class com.google.vending.licensing.ILicensingService-keep public class com.android.vending.licensing.ILicensingService# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native-keepclasseswithmembernames class * {    native <methods>;}# keep setters in Views so that animations can still work.# see http://proguard.sourceforge.net/manual/examples.html#beans-keepclassmembers public class * extends android.view.View {   void set*(***);   *** get*();}# We want to keep methods in Activity that could be used in the XML attribute onClick-keepclassmembers class * extends android.app.Activity {   public void *(android.view.View);}# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations-keepclassmembers enum * {    public static **[] values();    public static ** valueOf(java.lang.String);}-keepclassmembers class * implements android.os.Parcelable {  public static final android.os.Parcelable$Creator CREATOR;}-keepclassmembers class **.R$* {    public static <fields>;}# The support library contains references to newer platform versions.# Don't warn about those in case this app is linking against an older# platform version.

4，现在已经到了关键的时刻了，看你项目中有多少第三方jar包，就得让不被混淆，我是在proguard-project.text文件中做的处理，贴出整个代码了

# To enable ProGuard in your project, edit project.properties# to define the proguard.config property as described in that file.## Add project specific ProGuard rules here.# By default, the flags in this file are appended to flags specified# in ${sdk.dir}/tools/proguard/proguard-android.txt# You can edit the include path and order by changing the ProGuard# include property in project.properties.## 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 *;#}######## 其它第三方库#######-dontwarn com.netease.nrtc.**-keep class com.netease.nrtc.** {*;}-keep class alipay_lib.** {*;}-keep class android-support-v7-gridlayout.** {*;}-keep class library.** {*;}-keep class MPChartLib.** {*;}################httpmime/httpcore##########-libraryjars libs/httpclient-4.1.2.jar-libraryjars libs/httpmime-4.1.2.jar-keep class org.apache.http.** {*;}-dontwarn org.apache.http.**################gson##################-libraryjars libs/gson-2.2.4.jar-keep class com.google.gson.** {*;}#-keep class com.google.**{*;}-keep class sun.misc.Unsafe { *;

5，clean项目，会多出一个文件夹proguard

6，大功告成，打包就行了，最好打包后再在手机上跑着看看，有没有问题，最好连着电脑看log日志，有问题也不是什么大问题了，基本都能解决，主要是第三方jar包的有的混淆了，看log是那个混淆了-keep 那个就行
