Android插件化（一）：使用改进的MultiDex动态加载assets中的apk

转自：http://blog.csdn.net/nupt123456789/article/details/50411581

简介

为了解决65535方法数超标的问题，Google推荐使用MultiDex来加载classes2.dex,classes3.dex等等，其基本思想就是在运行时动态修改ClassLoader，以达到动态加载类的目的。为了更好的理解MultiDex的工作原理，可以先看一下ClassLoader的工作原理[1].然后参见PathClassLoader的源码，当然，它继承自BaseDexClassLoader，主要源码都在BaseDexClassLoader中。MultiDex加载离线apk的过程如下： 



我们可以在Application的onCreate方法或者Activity的attachBaseContext方法中开发加载。

动态加载assets中的apk

根据MultiDex的源码，我们可以修改其install方法，然后从assets资源中解压出所需要加载的apk文件，然后调用installSecondaryDexes方法，将其加载到当前Application的ClassLoader当中，这样，在运行的时候，就可以通过当前的ClassLoader查找到离线apk中的类了。

以上就是从assets中加载apk的核心代码。

DEMO运行

打开BundleApk项目，编译成apk。然后将BundleApk.apk文件拷贝到HostApk项目的assets目录，在HostApk的MainActivity方法的onCreate当中，调用AssetsMultiDexLoader.install(getApplicationContext());加载BundleApk.apk。然后我们就可以通过如下两种方式调用BundleApk中的类：
Class.forName

由于我们的HostApk没有BundleApk类的引用，所以我们需要用反射的方式调用。

loadClass

我们也可以直接获取当前的ClassLoader对象，然后调用其loadClass方法
