My-Code Siehe -

public void login(View view) { 
    switch (view.getId()) { 

     case R.id.signin: 
      String employCod = editTextUserCode.getText().toString(); 
      String branchCod = editTextBranchCode.getText().toString(); 
      String password = editTextPassword.getText().toString(); 
      onlogin(employCod, branchCod, password); 

      break; 

    } 
} 

private void onlogin(final String employCod, final String branchCod, final String password) { 

    class LoginAsync extends AsyncTask<String, String, String> { 
     /** 
     * Before starting background thread Show Progress Dialog 
     */ 
     boolean failure = false; 

     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      pDialog = new ProgressDialog(LoginActivity.this); 
      pDialog.setMessage("Attempting login..."); 
      pDialog.setIndeterminate(false); 
      pDialog.setCancelable(true); 
      pDialog.show(); 
     } 

     @Override 
     protected String doInBackground(String... args) { 

      // TODO Auto-generated method stub 
      // Check for success tag 


      String companyCode = "VO";

      try {

       params.add(new BasicNameValuePair("passWord", password)); 
       params.add(new BasicNameValuePair("loginBranch", loginBranch)); 
       Log.d("request!", "starting"); 
       // getting product details by making HTTP request 
       JSONObject json = jsonParser.makeHttpRequest(

       // check your log for json response 
       Log.d("Login attempt", json.toString()); 

       // json success tag 
       errflag = json.getString(TAG_SUCCESS); 
       if (errflag.equalsIgnoreCase("S")) { 
        Log.d("Login Successful!", json.toString()); 
        Intent i = new Intent(LoginActivity.this, MainActivity.class); 
        finish(); 
        String employName = json.getString("empName"); 
        i.putExtra("empName", employName); 
        startActivity(i); 

        return json.getString(TAG_MESSAGE); 
       } else { 
        Log.d("Login Failure!", json.getString(TAG_MESSAGE)); 
        return json.getString(TAG_MESSAGE); 

       } 

      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 

      return null; 

     } 


     /** 
     * After completing background task Dismiss the progress dialog 
     * **/ 

     protected void onPostExecute(String file_url) { 
      // dismiss the dialog once product deleted 
      pDialog.dismiss(); 
      if (file_url != null) { 
       Toast.makeText(LoginActivity.this, file_url, Toast.LENGTH_LONG).show(); 


      } 

     } 

    } 
    LoginAsync la = new LoginAsync(); 
    la.execute(employCod, branchCod, password);
