Android工程混淆打包：一个典型过程和示例文件

本例不含依赖工程的情况，如有依赖工程，请先导出为jar包再打包：

1. 基于Android 2.1以上版本；

2. 签名的密钥文件生成；

1）. 创建证书：keytool -genkey -alias mykey.keystore -keyalg RSA -keystore mykey.keystore 密码同系统登陆密码

3）. 查看证书库：keytool -list -keystore mykey.keystore

4）. 导出到证书文件：keytool -export -alias mykey.keystore -file mykey.crt -keystore mykey.keystore

5）. 导入证书的信息：keytool -import -keystore mykey.keystore -file mykey.crt mykey.crt导入到名为mykey.keystore的证书库中

6）. 查看证书信息：keytool -printcert -file mykey.crt

7）. 删除密钥库中的条目：

keytool -list -keystore mykey.keystore

keytool -delete -keystore mykey.keystore -alias mykey.keystore

8）. 修改证书条目的口令：keytool -keypasswd -alias mykey.keystore -keystore mykey.keystore

3. proguard.cfg文件

-optimizationpasses 5

-dontusemixedcaseclassnames

-dontskipnonpubliclibraryclasses

-dontpreverify

-verbose

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-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

#使用xml布局并且混淆apk时，请在混淆配置中加入以下这行代码

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

-keepclasseswithmembernames class * {

native <methods>;

}

-keepclasseswithmembers class * {

public <init>(android.content.Context, android.util.AttributeSet);

}

-keepclasseswithmembers class * {

public <init>(android.content.Context, android.util.AttributeSet, int);

}

-keepclassmembers class * extends android.app.Activity {

public void *(android.view.View);

}

-keepclassmembers enum * {

public static **[] values();

public static ** valueOf(java.lang.String);

}

-keep class * implements android.os.Parcelable {

public static final android.os.Parcelable$Creator *;

}

4. Build.xml文件

<?xml version="1.0" encoding="GBK"?>

<!-- 步骤

1.用aapt生成R.java

2.JAVAC编译JAVA文件

3.批处理生成classes.dex

4.aapt打包资源

5.apkbuilder包资源和类文件为APK文件

6.jarsinger 对APK进行签名-->
