> Currently, on both Android and iOS, we support calling a plugin with multiple arguments, but only support a single return value.
> If all your return values are json serializable, you can construct a json array or dictionary and return that, and that has gotten us this far.
> However, we have recently added support for sending ArrayBuffers, which are not json serializable.  Some plugins require returning data along with an ArrayBuffer result (such as a success indicator).
> We propose adding a new return type to CDVPluginResult (ios) and to PluginResult (android) which is some multi-value container, semantically a list of PluginResult.  The types this container supports are the same as we have supported until now, and the current PluginResults implementations can be written in terms-of a list of size 1 so as to support the common case while not diverging implementations.
