I've test WL.BusyIndicator like following code:
busyIndicator = new WL.BusyIndicator('content', {
text : 'saving'
});
busyIndicator.show();
setTimeout(function() {
busyIndicator.hide();
}, 3000);
The Information Center says BusyIndicator options can get 'text' in Android environment.
I can see the BusyIndicator shown on my Android Emulator (v4.0.4/v4.1.2/v4.2.2) but the text is default 'Loading'...
Note: the same happens in iOS as well.
My Worklight Studio version is: 6.0.0.201307241843
