All the examples that I found were not clear enough for me and they were about downloading a file. I'm running this code in my main activity and my problem is when the code sends the info to the server the app slows down as if it is frozen for 2 to 3 sec's then it continues to work fine until the next send. This http post sends four variables to the server (book, libadd, and time) the fourth is fixed

Some say it possible to some say to accomplish some say it's not. I am getting crazy on this. What I want is just to have the AsyncTaskTask showing a progressbar an external class. To do this I am passing the context as you can see in the main class. But whatever I try I get NullPointerException . Working code examples is appreciated. Thank you Using Android 2.2 by the way. main: import android.app.Activity; import android.os

I debugged the app countless times(really) and after doInBackground() method called i get the values i want to send to onPostExecute() method but the problem the onPostExecute() method is never called.
