Android外掛化（一）：使用改進的MultiDex動態載入assets中的apk
轉自：http://blog.csdn.net/nupt123456789/article/details/50411581
簡介
為了解決65535方法數超標的問題，Google推薦使用MultiDex來載入classes2.dex,classes3.dex等等，其基本思想就是在執行時動態修改ClassLoader，以達到動態載入類的目的。為了更好的理解MultiDex的工作原理，可以先看一下ClassLoader的工作原理[1].然後參見PathClassLoader的原始碼，當然，它繼承自BaseDexClassLoader，主要原始碼都在BaseDexClassLoader中。MultiDex載入離線apk的過程如下： 
我們可以在Application的onCreate方法或者Activity的attachBaseContext方法中開發載入。
動態載入assets中的apk
根據MultiDex的原始碼，我們可以修改其install方法，然後從assets資源中解壓出所需要載入的apk檔案，然後呼叫installSecondaryDexes方法，將其載入到當前Application的ClassLoader當中，這樣，在執行的時候，就可以通過當前的ClassLoader查詢到離線apk中的類了。

以上就是從assets中載入apk的核心程式碼。
DEMO執行
開啟BundleApk專案，編譯成apk。然後將BundleApk.apk檔案拷貝到HostApk專案的assets目錄，在HostApk的MainActivity方法的onCreate當中，呼叫AssetsMultiDexLoader.install(getApplicationContext());載入BundleApk.apk。然後我們就可以通過如下兩種方式呼叫BundleApk中的類：
- Class.forName
由於我們的HostApk沒有BundleApk類的引用，所以我們需要用反射的方式呼叫。
