android studio apk混淆

在Android Studio當中混淆APK實在是太簡單了，借助SDK中自帶的Proguard工具，隻需要修改app module 下的build.gradle中的一行配置即可。可以看到，現在build.gradle中minifyEnabled的值是false，這裡我們隻需要把值改成true，編譯出來的APK包就會是混淆過的了。如下所示：

buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
            signingConfig signingConfigs.release
        }
        debug {
            signingConfig signingConfigs.debug
        }
    }

其中：

minifyEnabled用于設定是否啟用混淆；

shrinkResources用于設定删除無效的Resources，shrinkResources依賴于minifyEnabled，必須一起使用；

proguardFiles用于標明混淆配置檔案。注意這裡是在release閉包内進行配置的，是以隻有編譯出正式版的APK才會進行混淆，Debug版的APK是不會混淆的。當然這也是非常合理的，因為Debug版的APK檔案我們隻會用來内部測試，不用擔心被人破解。

proguard-android.txt混淆配置檔案，該檔案存放于android studio的sdk目錄下androidsdk\tools\proguard，打開檔案如下：

# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-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.

android studio apk混淆

我就問你是不是感覺頭很大，哈哈别着急下面還有解釋。

這個就是預設的混淆配置檔案了，我們來一起逐行閱讀一下。

好了，這就是proguard-android.txt檔案中所有預設的配置，而我們混淆代碼也是按照這些配置的規則來進行混淆的。經過我上面的講解之後，相信大家對這些配置的内容基本都能了解了。

回到Android Studio項目當中，APK雖然已經成功混淆了，但是混淆的規則都是按照proguard-android.txt中預設的規則來的，當然我們也可以修改proguard-android.txt中的規則，但是直接在proguard-android.txt中修改會對我們本機上所有項目的混淆規則都生效，那麼有沒有什麼辦法隻針對目前項目的混淆規則做修改呢？當然是有辦法的了，你會發現任何一個Android Studio項目在app子產品目錄下都有一個proguard-rules.txt（proguard-rules.pro）檔案，這個檔案就是用于讓我們編寫隻适用于目前項目的混淆規則的。自定義混淆通用模闆如下：
