  • i think you should use AsyncTask you cant do network call on main thread – Himeshgiri gosvami May 11 '14 at 09:39
  • Search for `NetworkOnMainThreadException` - you need to do network ops on a background thread such as `AsyncTask`. http://stackoverflow.com/questions/6343166/android-os-networkonmainthreadexception – laalto May 11 '14 at 09:39
  • You should show code, but I think this is the problem: NetworkOnMainThreadException It must be that you have some network operation in main thread of the Activity you are trying to start. That is something you should not do and that is why you get this exception. – Bozic Nebojsa May 11 '14 at 09:41

  • But I'm using Asynctask..It works fine at first.But after i put this activity into tab layout., these errors occurred.Please help.Thanks – user3402438 May 11 '14 at 09:55

    You have `runOnUiThread()` in your asynctask. Guess what it does? – laalto May 11 '14 at 10:31

In android it is not a good practise to do network related operations on main thread of your activity.

For doing such things there are other methods like using AsyncTask.
