here

if(method == "POST")

you are using == for comparing String Contain which is not valid because == is used for Comparing object reference if you want to compare contain value then using String.equals as:

if(method.equals( "POST"))

or using equalsIgnoreCase

if(method.equalsIgnoreCase( "POST"))

@Android : now your error move from doInBackground to onPostExecute what is line number My_Task.java:204?

Android Over a year ago

a/c to Logcat it display error on " cus_name_txtbx.setText(my_task.getString(TAG_NAME)); "

Android Over a year ago

line no 204 is: cus_name_txtbx.setText(my_task.getString(TAG_NAME)); whats wrong in it??

@Android : NullPointerException means you are not getting value from JSON just try after setting static values in onPostExecute
