I'm build a app that consist of user login and registration but every time I test it on the emulator I receive a force close. Below are the errors I'm receiving in the log cat:

Your getting a StrictMode violation. This means that you are doing something blocking on the UI Thread. Hence the reason for

android.os.NetworkOnMainThreadException

From the rest of your LOG it appears your performing a web request. Make sure that HTTP request is wrapped in an AsyncTask (or something similar)

It seems like you are trying to do your login and registration on the main Thread. First of all this is bad practice, and it can't be done on recent API levels. All you need to do is make your network connections in a separate thread, be it an AsyncTask or just a plain old Thread()

as an example :

use this

public void login()
{
   new Thread(new Runnable() {

        @Override
        public void run() {
    //your network connection goes here
    }
   }).start();
}

instead of :

public void login()
{
    //your network connection goes here
}

Try to check the same in a mobile with internet connectivity. The logcat also displays that the emulator doesnt has a GPS connectivity.
