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-->
