} i am using foursqure functionality in my application in which user share any data so user can share on foursqure..,the problem is when i am using "StrictMode "functionality in my oncreate.,its not giving me error.,but when i am not using its giving me networkon minthread exception i am getting this exception in foursqure.when dialog is loading??what i do plese help me thankyou...:) here is my logcat logcat

@laalto sir.., when i am using strictmode option,i am not getting any error my,response is coming,but i am littile bit confuse where to use asyncronous task in application?can you help me? — rajshree, Jan 28 '14 at 13:55
If you are using StrictMode then you're just stopping the exception from being thrown. There's a reason why that exception gets thrown and that's because it is a bad idea to retrieve data from the internet on the UI thread. If you have a slow connection, which is a problem in many parts of the world, you'll end up with a hanging application which eventually gives a 'Force Close' message. That is NOT professional programming — Piyush, Jan 28 '14 at 14:02
@PiyushGupta sir i am confuse how i implement this,can you give me any example..,please...sir..:) — rajshree, Jan 28 '14 at 14:24

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); in your class, — Digvesh Patel, Jan 29 '14 at 14:10

Networking operations tend to take some time. That's why on Android, it's forbidden to perform Networking Tasks on the UI (foreground) thread. The System throws a NetworkingOnMainThreadException if you try it.

You have to move your Networking code to a Background thread. The easiest way to do that is by using an AsyncTask.
