Response:wrong. [user Registration Via Android App Using Http Post Not Working]

I was able to successfully make login work. Now, I am stuck up with registration. Response is wrong. public class Register extends Activity implements OnClickListener{ private

Solution 1:

try below code:-

HttpResponsehttpResponse= httpClient.execute(httpPost);

                if (httpResponse != null)
                {
                    InputStreamin= httpResponse.getEntity().getContent();
                    result = ConvertStreamToString.convertStreamToString(in);
                    // System.out.println("result =>" + result);
                }

convertStreamToString method

public String convertStreamToString(InputStream is) 
{
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();
    String line = null;
    try
    {
        while ((line = reader.readLine()) != null) 
        {
            sb.append(line + "\n");
        }
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    }
    finally 
    {
        try 
        {
            is.close();
        }
        catch (IOException e) 
        {
            e.printStackTrace();
        }
    }
    return sb.toString();
}

do not under stand :-

HttpResponsehttpResponse= httpClient.execute(httpPost); // getting response from server // where you use this response and why using below line or whats the benefit of below line

                    ResponseHandler<String> responseHandler = newBasicResponseHandler();
                    finalStringresponse= httpClient.execute(httpPost, responseHandler);

Try this code using AsyncTask

publicclassRegisterextendsActivityimplementsOnClickListener{

    privateStringmTitle="Write.My.Action";

    privatestaticfinalStringLOGTAG="tag";
    public EditText fullname, email, password;
    private Button register; 
    private ProgressDialog mDialog; 

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.register);
        getActionBar().setTitle(mTitle);

        fullname = (EditText) findViewById(R.id.fullname);
        email = (EditText) findViewById(R.id.editText2);
        password = (EditText) findViewById(R.id.editText1);

        register = (Button) findViewById(R.id.button1);

        register.setOnClickListener(this);
    }

    @OverridepublicvoidonClick(View v) {
        switch (v.getId()) {
        case R.id.button1:
            mDialog = newProgressDialog(Register.this);
            mDialog.setMessage("Attempting to Register...");
            mDialog.setIndeterminate(false);
            mDialog.setCancelable(false);
            mDialog.show();

            newRegisterUser().execute();
        }

    }

    publicclassRegisterUserextendsAsyncTask<Void, Void, String>
    {

        @OverrideprotectedvoidonPreExecute() {
            // TODO Auto-generated method stubsuper.onPreExecute();
        }

        @Overrideprotected String doInBackground(Void... params) {
            // TODO Auto-generated method stubHttpClienthttpClient=newDefaultHttpClient();
            HttpPosthttpPost=newHttpPost("myurl");

            System.out.println("httpPost is: " + httpPost);

            Stringfullname_input= fullname.getText().toString().trim();
            Stringemail_input= email.getText().toString().trim();
            Stringpassword_input= password.getText().toString().trim();

            //adding data into list view so we can make post over the server

            List<NameValuePair> nameValuePair = newArrayList<NameValuePair>();
            nameValuePair.add(newBasicNameValuePair("fullname",  fullname_input));
            nameValuePair.add(newBasicNameValuePair("email",  email_input));
            nameValuePair.add(newBasicNameValuePair("password",  password_input));

            System.out.println("namevaluepair is: " + nameValuePair);
            httpPost.setEntity(newUrlEncodedFormEntity(nameValuePair));

            //execute http post resquestHttpResponsehttpResponse= httpClient.execute(httpPost);



            ResponseHandler<String> responseHandler = newBasicResponseHandler();
            finalStringresponse= httpClient.execute(httpPost, responseHandler);

            System.out.println("Response is: " + response);

            return response;
        }

        @OverrideprotectedvoidonPostExecute(String result) {
            // TODO Auto-generated method stubsuper.onPostExecute(result);

             if(response.equalsIgnoreCase("Signed Up")){
                    runOnUiThread(newRunnable() {

                        @Overridepublicvoidrun() {
                            startActivity(newIntent(Register.this, Registration_Success.class));

                        }
                    });
                }else {
                    showAlert();
                }
        }

    }

     publicvoidshowAlert(){
         Register.this.runOnUiThread(newRunnable() {

            @Overridepublicvoidrun() {
                AlertDialog.Builderbuilder=newAlertDialog.Builder(Register.this);
                builder.setTitle("Registration Error");
                builder.setMessage("Please, try registration again!")
                        .setCancelable(false)
                        .setPositiveButton("OK", newDialogInterface.OnClickListener() {

                            @OverridepublicvoidonClick(DialogInterface dialog, int which) {
                                // TODO Auto-generated method stub

                            }
                        });
                AlertDialogalert= builder.create();
                alert.show();

            }
        });
     }
}

Hope this helps you!!!

Try using Volley if not. It's faster than the ussual HTTP connection classes. Example:

RequestQueue queue = Volley.newRequestQueue(this);
    String url = "url";
       JSONObject juser = newJSONObject();     
       try {                   
                juser.put("locationId", locID);
                juser.put("email",  email_input);
                juser.put("password",  password_input);
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    JsonObjectRequest jsObjRequest = newJsonObjectRequest(Request.Method.POST, url, juser, newResponse.Listener<JSONObject>() {

        @OverridepublicvoidonResponse(JSONObject response) {
            // TODO Auto-generated method stub
            txtDisplay.setText("Response => "+response.toString());
            findViewById(R.id.progressBar1).setVisibility(View.GONE);
        }
    }, newResponse.ErrorListener() {

        @OverridepublicvoidonErrorResponse(VolleyError error) {
            // TODO Auto-generated method stub

        }
    });

    queue.add(jsObjRequest);

Like @Andrew T suggested , I am posting my solution. The mysql_error()helped me debug the issue. mysql_error() displayed in the Logcat that "register table is not found" .. but the table name is registers. I was missing "s" at the end.

$fullname = $_POST['fullname'];
    $email = $_POST['email'];
    $password = $_POST['password'];

    $insert_data = "INSERT INTO registers(id, fullname, email, password)
        Values ('','$fullname', '$email', '$password')";

    $insert_result = mysql_query($insert_data) or die(mysql_error());
    //echo "Signed Up";

    if($insert_result){
    echo"Signed Up";
    }
    else{
     echo"wrong!";
    } 

Everything worked perfect after that. Again, thank you all for your time and solutions. Everyone's suggestions are great, but I can not accept any answer at this point.. sorry:(
