Android Asyntask for web service
===

I'am developing an application which is totally based on fetching data from web services.
In one activity I have to call almost 5 6 different web services which displays different information. This application is target v 2.3 to 4.x, as there are no network communication allowed on main ui thread so I am making  5 6 AsyncTask classes, because its post execute helps me a lot in displaying.

Now I am confused is this approach right or wrong, making 5 6 AsyncTask classes(can't reduce the number of web services or call in one AsyncTask because I have to check data again and again). Is this a good approach or should I change my pattern, and then switch to what approach.
Using this approach my application is working very nice and smooth on all devices.
