>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: CordovaJS
>    Affects Versions: 3.3.0
>         Environment: Android 
>            Reporter: Nick Eaket
>            Priority: Minor

> Currently if the Cordova-js Android Native->JS message handler registers on the 'online'/'offline
event.  If a Native message is sent using CordovaWebView.sendJavascript(...) and Cordova-js
is currently not loaded, the web view will remain in the 'offline' state.  When Cordova-JS
is finally loaded, sending another message from Native->JS will continue to fill up the
message queue.  Cordova-JS will currently never see if the Native code has new messages.
> Steps to reproduce:
> 1. Create a new Cordova Android app
> 2. Have the app load a web page that does not load cordova-js
> 3. Have a Cordova Native plugin send a JavaScript message to the app.  (expected to be
ignored, since cordova-js is not loaded)
> 4.  Navigate to a second web page that does load cordova-js
> 5. Repeat step 3.
> Expected:
> Cordova-js should receive the message from step 5
> Suggested Fix:
> Add a call to 'pollOnceFromOnlineEvent()' after the 'deviceready' event.  
> The call could potentially go here.  https://github.com/apache/cordova-js/blob/master/src/android/exec.js#L266
