Andrew Grieve commented on CB-6746:
-----------------------------------
We should certainly fix how broken this is (your fix sounds good), but likely
I'd want to log a warning if this case occurs. It's generally not a good idea
to use sendJavascript() at all and instead to always use sendPluginResult where
keepCallback=true. Is it one of Cordova's plugins that causes this to happen?

> 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.
