/**
* 需要fakeContext并不是因为插件取不到自己的meta-data，
* 而是因为针对需要appkey的sdk插件，需要同时正确的取到下面3个值，
* 1、packageName
* 2、meta-data
* 3、signatures
*
* 默认情况是：
* 1、当packageName是宿主的时候，meta-data和signatures都会取到宿主的值
* 2、当packageName是插件的时候，meta-data和signatures都会取到插件的值
*
* 然而针对需要appkey的sdk插件来说，一般情况是这样：
* 1、packageName需要是宿主，因为appkey是注册的宿主的appkey
* 2、meta-data需要是插件，因为meta-data是放在插件的manifeat文件中
* 3、signatures需要是宿主，因为appkey是注册的宿主的signatures
* 因此需要fackeContext来实现这种组合
*
* 但是，如果注册appkey的时候，就直接使用了插件的packageName、meta-data、signatures
* 则无需使用fakeContext，直接使用插件的Application即可。
