本文将带你了解Android应用开发之android混淆问题解析，希望本文对大家学Android有所帮助。

应用开发完了，测试没问题了，快上市场了，这时候就要混淆加固多渠道打包加上线了，所以，混淆就来了：
      混淆是什么，就是把类名，方法名，变量名给弄成简单的单词或者字母来代替，从而防止别人反编译后轻松的得到源码。与其说我们配置混淆，不如说我们来配置哪些包里面的哪些类不要被混淆，也就是在下面的那个文件里声明一下，哪些不要给我混淆：
    1.在module的build.gradle的android标签里
buildTypes { release   {  signingConfig   signingConfigs.<strong>release</strong><strong>    </strong>shrinkResources   <strong>true</strong><strong>    </strong>minifyEnabled <strong>true</strong><strong>    </strong>zipAlignEnabled   <strong>true</strong><strong>    </strong>proguardFiles   getDefaultProguardFile(<strong>'proguard-android.txt'</strong>),   <strong>'proguard-rules.pro'</strong><strong></strong><strong>   </strong>}  debug {  signingConfig   signingConfigs.<strong>release</strong><strong>    </strong>shrinkResources <strong>true</strong><strong>    </strong>minifyEnabled   <strong>true</strong><strong>    </strong>zipAlignEnabled   <strong>true</strong><strong>    </strong>proguardFiles getDefaultProguardFile(<strong>'proguard-android.txt'</strong>),   <strong>'proguard-rules.pro'</strong><strong>   </strong>} }
    2.在proguard-rules.pro里

这里面我也还有一些不是很明白，比如android的很多系统依赖，比如通过gradle配置的一些v4，v7包里面的依赖是不是也要配置不要被混淆呢？但是，我的应用小，做了上面的事情就够了。
