Off the cuff, it would seem as though you're getting a 401 Unauthorized
error, due to a malformed Authorization header.


That's a distinct possibility.

1. xml view defination to take event handler class name

In the meantime, you could easily automate this behavior on your side:

- one method is to add custom tags to your layout XML. Use an
XmlPullParser to parse the XML and when you find an element with an
android:id and your tag, use reflection to associate a listener to it.

- another method would be to use special id names, for example
"__name". Inflate your view content, visit the view hierarchy and for
each view id that matches the name you can automatically attach a
listener found via reflection.

In both cases you can just make an utility method that does this and
use it everywhere.
The "visit xml/hierarchy" and "reflection" keywords should tell you
it's going to be expensive.

2. Using AbsolluteLayout even though it is deprecated

Hi Guys,

Ihave used absolute layout in the application that I had earlier
developed and since it has been deprecated now it has been quite
difficult in changing the layout params, can I go forward and publish
the application without removing the absolute layout? what will be the
problems because of this? will this layout become obsolute in the
future?

Regards,
R.Karthik
