Well then you'll have to run `gettext` on the UI thread. Use your favourite search engine on the terms `android` and `run on UI thread` - you'll find kajillion of answers. — m02ph3u5, Apr 24 '16 at 17:04

Do not refer to widgets from inside doInBackground(). Pass in the values you are getting from those EditText widgets, either to a constructor on your SendPostReqAsyncTask, or as additional strings to your execute() call.

you mean i just need to change this section of my code with the section u write ? `private void insertToDatabase(String name, String add){ class SendPostReqAsyncTask extends AsyncTask { @Override protected String doInBackground(String... params) { String paramUsername = params[0]; String paramAddress = params[1]; String name = editTextName.getText().toString(); String add = editTextAdd.getText().toString(); List nameValuePairs = new ArrayList();` – mh9 Apr 24 '16 at 17:10
`you mean i just need to change this section of my code with the section u write ?` yes. I can't read the code in your comment though. – F43nd1r Apr 24 '16 at 17:12
ok i change it but =( now i have red lines under name and add in this line of code : `final String name = editTextName.getText().toString();` – mh9 Apr 24 '16 at 17:19
That is a name conflict with the parameters. Rename either the final variables or the method parameters. – F43nd1r Apr 24 '16 at 17:22
no red lines now thank you really soooooooooooo mush – mh9 Apr 24 '16 at 17:26
