08-29         


        

Answer 1

Probably the error arise because of this line

 Toast.makeText(getApplicationContext(),
                    e.getMessage(),
                    Toast.LENGTH_LONG).show();

inside doInBackground.Toast has to been shown on the UIThread. Instead you are using the doInBackground thread to show it. In general, all the operations regarding the UI have to be executed on the UI Thread. If you want to fix, you could use an handler to post a runnable on the UI Thread queue that shows a Toast
