org.json.JSONException: Value <br of type java.lang.String cannot be converted to JSONObject

Question

I m trying to do a registration page from an android activity connectiong the datas to my sqldatabase, I m getting this error " org.json.JSONException: Value

First of all, could anyone advise me on how to debug my program when using an mysql database with php script for an android application ? Cause I usually use the log cat but here the errors aren't as clear :S ...

Here is the activity code :

public class Subscribe extends Activity {

    Button bSubscribe;
    EditText etPwdSub, etPwdConf, etLoginSub, etNameSub, etFnSub;
    String result = null;
    InputStream is = null;
    String donnees = "";

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.subscribe);

        etLoginSub = (EditText) findViewById(R.id.etLoginSub);
        etPwdSub = (EditText) findViewById(R.id.etPwdSub);
        etPwdConf = (EditText) findViewById(R.id.etPwdConf);
        etNameSub = (EditText) findViewById(R.id.etNameSub);
        etFnSub = (EditText) findViewById(R.id.etFnSub);

        bSubscribe = (Button) findViewById(R.id.bSubscribe);        
        bSubscribe.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {

                Pattern p = Pattern.compile(".+@.+\\.[a-z]+");
                Matcher m = p.matcher(etLoginSub.getEditableText());

                if (m.matches() == false) {

                    Toast.makeText(
                            getBaseContext(),
                            "Le champs email ne correspond pas au format d'une adresse mail",
                            Toast.LENGTH_SHORT).show();
                } else {

                    // autre méthode : etPwdSub.equals("")
                    if (etPwdSub.getEditableText() != null
                            && etPwdConf.getEditableText() != null

Your request to http://192.168.1.101/spotnshare/subscribe.php is failing and returning a non-JSON string (probably a PHP error). You can print out the value with a

Log.i("tagconvertstr", "["+result+"]");

before the new JSONObject call to see what you're getting before parsing it.

EDIT: if you are using Eclipse you can set a break point and step through to see what's going on.

Thanks I manage to correct some of the errors 2 ';' were missing and I could see the error with Log.i("tagconvertstr", "["+result+"]");

The msg that it is showing is something like that :

[<br/ > font size = 1 table class=''xdebug-erroe' dir='ltr' ... loads of html code that wasn't in my initial code then....{"message":"Problem sending you the activation mail !"}]

So there's a problem with the json format on that message "Problem sending you the activation mail" but the user was registered OK!

So the second time i would try that code it would show me in a correct json format : "This email has already been used" ! (without any errors) but i still can't find the error in my php code : S

try preventing any output before your print and change the print to echo

you may also remove the closing ?> to prevent further output after the php script

<?php
ob_start();
if( isset($_POST['login']) && isset($_POST['pwd']) && isset($_POST['name']) && isset($_POST['firstname'])) {

    include("connexion_bdd.php");

    if(connexionBDD() == 1){

        $login = $_POST['login'];
        $pwd = $_POST['pwd'];
        $name = $_POST['name'];
        $firstname = $_POST['firstname'];

        $sql = "SELECT colUserID
                FROM userTable 
                WHERE colUserLogin = '".$login."' ";

        $req = mysql_query($sql);
        $resultat=mysql_num_rows($req); 

        if($resultat==0){
            $temps = time();
            $clef = md5($login . $temps);

            $req = mysql_query("INSERT INTO userTable(colUserLogin, colUserPwd, colUserName, colUserFirstname, colUserKey, colUserDate)
                                        VALUES( '$login', '$pwd', '$name', '$firstname', '$clef', '$temps')");

            if($req){
                    $destinataire = $login;

                    }
            }
            else{

You should set Content-Type header before sending back the response.

header('Content-Type: application/json');
print(json_encode(array("message" => $msg)));

Check this : Returning JSON from a PHP Script

I have the same problem; i found the solution the easy way.

In Java code just type Log.e("anyText",response); In logCat it will show you what is problem
