edit: initial problem userdata class in launch configuration. took out , called method loaddata() oncreate() in mainactivity activity.

android's entry point isn't public static void main(string[] args) regular java application, uses activities instead.

you should putting code within oncreate(), oncreateview(), onstart() or other applicable method in activity (or fragment).

read on activity , its lifecycle (and fragment lifecycle) see gets executed when take where/when code should executed.

edit: possible have class main method in android takes doing configured , not trying do. here related question , answer (and another) on topic in case you're interested.

edit2: sec issue

your stacktrace shows:

caused by: android.os.networkonmainthreadexception ... @ com.example.virginmobileinfo.minuteschecker.userdata.downloaduserprofile(userdata.java:31)

you attempting create network interactions on ui thread android doesn't allow create app unresponsive duration of call.

you need @ asynctask or other background thread handling. android docs on topic are here
