Joe Bowser resolved CB-3064.
----------------------------

    Resolution: Not A Problem

If you leave an app in Android, it isn't stopped, it is paused.  So, for example, if you go
off and do something like play Ingress, and then come back, the application will restore its
state and move on.  When the activity restores its state, it loads the data from the intent
where the Config class stores the data read from config.xml.

In the config.xml file, I put the following as the errorUrl:
    <preference name="errorUrl" value="file:///android_asset/www/ohnoes.html" />

Then in DroidGap.java, I added this code in onResume:
//Code to test CB-3064
        String errorUrl = this.getStringProperty("errorUrl", null);
        LOG.d(TAG, "CB-3064: The errorUrl is " + errorUrl);

If we lose this data, this should not say ohnoes.html.  However, it appears that it does.
 As long as we have the state of the intent, we should have the data.  If the application
is killed, it has to go back through the initial init process.

This was tested on Android 4.2.2 (Nexus 7) , Android 4.1.x (Samsung Galaxy S3) and Android
2.3.6 (Nexus S).  If your device is a special case, please let us know and we can re-open
this issue.

>          Issue Type: Bug
>          Components: Android
>    Affects Versions: 2.5.0, 2.6.0

> The preferences in the config.xml file are not read again if application exits and then
restarts.
> A simple test is to set the background color to GREEN (-16711936 or [0xff00ff00]) and
use an html page with transparent background. 
> The first time it is run, the application correctly displays a green background but then,
after exiting by pressing the back or home button, and re-running it, the background stays
black.
> Forcing the application thread to stop from the Android settings menu seems to cause
the preferences file to be read again.
