    I'll add a comment to the code explaining this. It has to do with how we encode plugin
results. If we were to just send one event object, we would have to first translate the PluginResult
obtained by the ResumeCallback into something we could place in the event plugin result's
JSONObject. Instead of duplicating our PluginResult decoding code on the Native side of things,
I just send back two results and handle it in platform.js

>             Project: Apache Cordova
>          Issue Type: Improvement
>          Components: Android
>            Reporter: Bnaya
>
> In android when you have a plugin that opens new activity the CordovaActivity will be
killed and you won't get the result from the plugin.
> The new activity will get the results but because the plugin objects are dead and the
webview reloaded you can get the data to the js callback.
> The most noticeable example is the camera plugin. (And maybe its the same with even more
platforms)
> possible solution for this is to add metadata to the device ready event with incoming
data from plugins.
