             Summary: Support returning multiple plugin-result values from native->js
                 Key: CB-2239
                 URL: https://issues.apache.org/jira/browse/CB-2239
             Project: Apache Cordova
          Issue Type: Improvement
          Components: Android, iOS
    Affects Versions: 2.3.0
            Reporter: Michal Mocny
            Assignee: Michal Mocny
            Priority: Minor


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.
