             Summary: Android's JS->Native ONLINE_EVENT does not work when cordova-js is not loaded before the first message
                 Key: CB-6746
                 URL: https://issues.apache.org/jira/browse/CB-6746
             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
