You can’t just instantiate your Activity and access the TextView members on it. This doesn’t make any sense: indoor_patient ins=new indoor_patient(); String webUrl = “http://10.0.3.2:8084/data_web/indoorPatient.jsp?sr_no=” + ins.sr_no.getText().toString() Instead you could figure out what your webUrl is in your onClick() method and pass in the complete URL as a parameter to the AsyncTask: submit.setOnClickListener(new View.OnClickListener() { … Read more

There a number of REST libraries that do more or less for you. Arguably, the most popular for Android are Retrofit (https://github.com/square/retrofit) and my personal favourite RoboSpice (https://github.com/stephanenicolas/robospice) for two simple reasons: runs as a service and works alongside Activity lifecycle.
