Hi guys,

i’m using mobione 2.1 preview and tried to use the eventsource interface from html5 in my application for android and as a web application. But in both applications it didn’t work.
The emulator doesn’t know EventSource, so all the tests have to be at the device (Samsung S2) directly. At the device i can’t debug helpfully.
First I try to initialize the ES component in the phoneui.documentReadyHandler but I got a black screen, without seeing my formular or websurface. The next step was to load it in a seperat function and call it with a delay of two seconds with “setTimeout”: now I can see the surface but after that nothing happend. If I place an alert box before and another one behind the

esObj = new EventSource('...');

statement, the first alertbox appear, the second was never seen.

What I want to know is: how can I use the eventsource interface in mobione. It seems like that it isn’t async (so I never see the results, because the connection will never terminated). Must I use a backgroundworker? or is there no support for EventSource, yet? Does anybody know a solution?

Thank you so far.

Best regards
Kasalop

At this time (MobiOne 2.1 and earlier ver) the Test Center does not support server-side events and websockets apis. We realize the importance of supporting these and other emerging html5 core apis. We are working to prioritize their inclusion in upcoming mobione versions.

@Wayne:

ok. No problem. But the application at the device have to work, I thought. so i want to know if the error is in the software or is in front of the computer (just me) 😉 I can’t figure out, because the debugging at the device is very hard. i tried to lookup if the EventSource class is defined and test this code:

alert(EventSource);

The messagebox show something like this: function EventSource() { [native code] }
I think its already implemented, but it doesn’t work?!

With best regards

EDIT: I have a general question too. How do you parse the html and interpret the javascript code? Do you use an own interpreter, or do you use the buildin browser-engine of the devices? In the second case there is a problem: http://caniuse.com/eventsource there is no support for that yet in android.
EDIT2: ok. I figured out that you use the internal android borwser. Now I installed Opera Mobile and now it works (with a little error, but I think, I can do a workaround). But its very uncomfortable that all my users have to install the Opera browser. I think about to write my own ES class.
