What's wrong with this there's no error when I'm debugging.. Thanks in advance:)

Answer 1

Your problem is that you are accessing the web from the main thread which is forbidden in Android (throws exception). The reason for that is that web communications are usually time consuming and might block the user for too long a time hanging the application.

You should use either the Android specific AsyncTask class or ordinary Thread for web-related communications, also for Database communications, but in your case the latter comprises of the first.

PS: Here is a thread of SO that illustrates an easy example of how you use AsyncTask. You should usually define the logic to be executed after the call is executed as callback in the onPostExecute method, very rearely you can also wait for the background thread to finish (not advisable at all).

NOTE: The application runs either in emulator or oni real device, but for both they need network calls to access your desktop machine.
