Android代碼混淆及項目發布步驟記錄

本來整理了一份Android項目混淆與發布的文檔，突然想到何不寫篇博客，分享一下呢，如是便有了本文。

Android代碼混淆及項目發布步驟記錄

一、清理代碼中的調試信息，如Log、System.out

二、在清單文件中修改版本為當前版本，如果需要更新數據庫，則需要在配置類或配置文件中修改程序數據庫版本。

三、在清單文件中將項目的debugable設置為false

四、創建簽名證書keystore文件

五、在項目中的project.properites文件中添加語句proguard.config=proguard-project.txt來指定混淆規則文件

六、配置proguard-project.txt文件

七、如果項目引用了Library Project，則Eclipse應該會在project.properties文件中自動生產android.library.reference.1..n=../LibraryProjectName

八、如果項目中包含svntmp(通常位於項目的bin文件夾下)，在打包時應及時刪除,否則會導致打包失敗。

九、項目打包，安裝測試(最好是使用現有生成包進行升級測試)

附：示例proguard-project.txt文件及相應說明：

# This is a configuration file for ProGuard.

# http://proguard.sourceforge.net/index.html#manual/usage.html

# Optimizations: If you don't want to optimize, use the

# proguard-android.txt configuration file instead of this one, which

# turns off the optimization flags. Adding optimization introduces

# certain risks, since for example not all optimizations performed by

# ProGuard works on all versions of Dalvik. The following flags turn

# off various optimizations known to have issues, but the list may not

# be complete or up to date. (The "arithmetic" optimization can be

# used if you are only targeting Android 2.0 or later.) Make sure you

# test thoroughly if you go this route.

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

-optimizationpasses 5

-allowaccessmodification

-dontpreverify

#-dontoptimize

# The remainder of this file is identical to the non-optimized version

# of the Proguard configuration file (except that the other file has

# flags to turn off optimization).

1.藍色內容具有通用性質，可以復制黏貼；

2.橙色內容用於指定程序中用到的jar文件(可以看到引用的Library Project不需包含，因為他們已經在project.properties文件中指定了)。

3.紅色內容用於表示保留(不混淆)引用的jar包中的內容。

4.草綠色內容用於表示保留本地的bean文件下的實體類不被混淆。

5.紫色內容用於表示保留本地涉及反射的類不被混淆。

6.綠色內容用於特別處理Web JS與本地原生組件之間的調用過程不被混淆。
