編輯：關於Android編程
1 代碼混淆的作用 Java 是一種跨平台的、解釋型語言，Java 源代碼編譯成 class 文件中。由於跨平台的需要，Java 字節碼中包括了很多源代碼信息，如變量名、方法名，並且通過這些名稱來訪問變量和方法，這些符號帶有許多語義信息，很容易被反編譯成 Java 源代碼。為了防止這種現象，我們可以使用 Java 混淆器對 Java 字節碼進行混淆。 混淆就是對發布出去的程序進行重新組織和處理，使得處理後的代碼與處理前代碼完成相同的功能，而混淆後的代碼很難被反編譯，即使反編譯成功也很難得出程序的真正語義。被混淆過的程序代碼，仍然遵照原來的檔案格式和指令集，執行結果也與混淆前一樣，只是混淆器將代碼中的所有變量、函數、類的名稱變為簡短的英文字母代號，在缺乏相應的函數名和程序注釋的況下，即使被反編譯，也將難以閱讀。同時混淆是不可逆的，在混淆的過程中一些不影響正常運行的信息將永久丟失，這些信息的丟失使程序變得更加難以理解。 混淆器的作用不僅僅是保護代碼，它也有精簡編譯後程序大小的作用。由於以上介紹的縮短變量和函數名以及丟失部分信息的原因， 編譯後 jar 文件體積大約能減少25% ，這對當前費用較貴的無線網絡傳輸是有一定意義的。 同樣，在android開發過程中，代碼的安全也很重要，從2.3開始，我們在創建android工程時會自動創建兩個文件proguard-project.txt和project.properties文件，其中默認情況下並沒有開啟代碼混淆，如果需要開啟，將project.properties文件中的#proguard.config=${sdk.dir}/tools/ proguard/ proguard-android.txt:proguard-project.txt這一行中的#去掉即可，然後編寫混淆文件proguard-project.txt.
