In asyncTask you cannot call Toast in doInBackground function... you can show your toast in onPostExecute(String result) so your code should be like this.
if (success == 1) {
// successfully created product
Intent i = new Intent(SignUpActivity.this, RegisterActivity.class);
i.putExtra("number", sms + "");
startActivity(i);
//closing this screen
//finish();
} else {
// failed to create product
return "false";
}
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
pDialog.dismiss();
if (result == "false")
Toast.makeText(SignUpActivity.this, "User Name already exists. Please choose another user name ", Toast.LENGTH_LONG).show();
}
In doInBackgound you just process your data but you can't change the UI of the activity. if you want to change the UI you either do it in onPreExecute() or in onPostExecute(String result)
EDIT!!
ahhhhhhhhh please remover this block
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
}
and replace it with part of my code
which is
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
pDialog.dismiss();
if (result == "false")
Toast.makeText(SignUpActivity.this, "User Name already exists. Please choose another user name ", Toast.LENGTH_LONG).show();
this should be out of the doInBackground method and inside the asynctask
so it all will look like this:
class CreateNewProduct extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(SignUpActivity.this);
pDialog.setMessage("Creating a new account..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/**
* Creating product
* */
protected String doInBackground(String... args) {
String name = editTextUserName.getText().toString();
String password = editTextPassword.getText().toString();
String mobile = editMobileNumber.getText().toString();
String sms = Integer.toString(number);
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name", name));
params.add(new BasicNameValuePair("password", password));
params.add(new BasicNameValuePair("mobile", mobile));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_data,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(SignUpActivity.this, RegisterActivity.class);
i.putExtra("number", sms + "");
startActivity(i);
//closing this screen
//finish();
} else {
// failed to create product
return "false";
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
pDialog.dismiss();
if (result == "false")
Toast.makeText(SignUpActivity.this, "User Name already exists. Please choose another user name ", Toast.LENGTH_LONG).show();
}
}

This is not an answer, I have found some issues, so I have rewritten your php file. All the responses returned as json object except last message, may be the reason for your android app closing issue.
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['name']) && isset($_POST['password']) && isset($_POST['mobile'])) {
$name = $_POST['name'];
$password = $_POST['password'];
$mobile = $_POST['mobile'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
$result1 = mysql_query("SELECT name FROM numerol WHERE name = '$name'");
if (mysql_num_rows($result1)==0) {
// mysql inserting a new row
$result = mysql_query("INSERT INTO numerol(name, password, mobile) VALUES('$name', '$password', '$mobile')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Product successfully created.";
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "User Name already exists, Please choose another username";
}
}else{
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
}
echo json_encode($response);
Note Use mysqli_* functions instead of mysql_* functions (deprecated)

Try this:
/**

* */
class CreateNewProduct extends AsyncTask<String, String, String> {
int success = 0;
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(SignUpActivity.this);
pDialog.setMessage("Creating a new account..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/**
* Creating product
* */
protected String doInBackground(String... args) {
String name = editTextUserName.getText().toString();
String password = editTextPassword.getText().toString();
String mobile = editMobileNumber.getText().toString();
String sms = Integer.toString(number);
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name", name));
params.add(new BasicNameValuePair("password", password));
params.add(new BasicNameValuePair("mobile", mobile));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_data,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
success = json.getInt(TAG_SUCCESS);
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**

* **/
protected void onPostExecute(String file_url) {
if (success == 1) {
// successfully created product
Intent i = new Intent(SignUpActivity.this, RegisterActivity.class);
i.putExtra("number", sms + "");
startActivity(i);
//closing this screen
//finish();
} else {
// failed to create product
Toast.makeText(SignUpActivity.this, "User Name already exists. Please choose another user name ", Toast.LENGTH_LONG).show();
}
// dismiss the dialog once done
pDialog.dismiss();
