I'm not sure if this is the cause of your problem, but why are you calling 'client.getConnectionManager().shutdown()'?
You can keep the 'DefaultHttpClient client' around and reuse for multiple requests. The first one you get may be slow, but it may speed up subsequent requests. Shut-down the 'client' only on an onDestroy(). On Nov 18, 6:00 pm, Wipeout <[email protected]> wrote: > Hey guys, > This is my first post to the Android Developers group.
