AsyncTask Syntax Errors

Question

I have no idea what I've done wrong - but I'm having several issues with compiling the following code after combining the source code from two different files I had and implementing AsyncTask. Any suggestions as to what could be causing these issues (as a learning experience) and if it's not too complicated a way to resolve them is appreciated.

(Thanks in advance!)

PROBLEMS:

Description Resource Path Location Type

The nested type AddEditCountry cannot hide an enclosing type    AddEditCountry.java /Game Demo/src/com/nfc/gamedemo line 159    Java Problem
Syntax error, insert "AssignmentOperator Expression" to complete Expression AddEditCountry.java /Game Demo/src/com/nfc/gamedemo line 153    Java Problem
The left-hand side of an assignment must be a variable  AddEditCountry.java /Game Demo/src/com/nfc/gamedemo line 153    Java Problem

P.S.

...never appears to hit the server (I'm checking the logs - no changes when clicking submit in the app which is supposed to send the string above - and if I paste that URL in a browser it works successfully)

Also - the reason it never appears on the server might be being caused by the fact I have to hit space before I can click submit because the text box is required before clicking submit - I think I may need to eliminate the text box entirely (I don't need it at all - I just want to send the predefined string of data) but Im not sure I know how to do so without butchering the source code.

I have modified your code try this pastebin.com/w96zfcPe, you haven't clarified me when do you want to execute your asyncTask — Pragnani
I ran the source code provided - almost perfect! Still have a few errors in the problem log and the string of data never hits the server - but I feel like we're getting VERY close to having it working! — FLDev2013

new MyAsyncTask().execute // this is wrong

execute() is method

call like this

new MyAsyncTask().execute("");

You code have lot of Errors. You have placed code out side of outside of onCreate
