Android Error parsing data org.json.JSONException: Value <br><table of type java.lang.String cannot be converted to JSONObject

I am trying to display information depending on the item pressed in a ListView. When click the item in List view,it will display the subject information.
But i faced a problem that is when click the item in List view,it cannot display the subject information based on the item that i clicked and display error in logcat.
Logcat Json response show that success get the subject information Single Product Details but still failed display subject information.Thanks

Search remote database Android app

I want to create an Android app to be a search engine that can
search my remote database from server like MAMP,
list the search results and
select one of the results to view details.
I have already set up the database.
Search.java - the launch page that shows only a search bar, allows user to search:
public class Search extends Activity implements OnClickListener{
private EditText searchterm;
private Button mSubmit;
private SharedPreferences preferences;
private String preFileName="searchrequest"; //this is the Preference file Name

prefKey.setText(preferences.getString(preFileName, "not_set"));
}

Problems:
How to save the search results from Search.java and let another activity Result.java to list results?
Save this from the php in first activity:
while ($row = $result->fetch_assoc()) {
$records[] = array('title'=>$row["title"], 'address'=>$row["address"],
'company'=>$row["company"], 'id'=>$row["id"], 'brand'=>$row["brand"]); // push into the array
}
//update our repsonse JSON data
array_push($response["records"], $records);
echo json_encode($response);
and put as listview in second activity (Result.java)??
Result.java --> select one of the results in list view, how to get details by searching database by posting id of the item?

I solved my question by putting this within Search.java to test whether can search:
#Override
protected String doInBackground(String... args) {
// TODO Auto-generated method stub
// Check for success tag
int success;
String searchquery = searchterm.getText().toString();
try {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("searchquery", searchquery));
Log.d("request!", "starting");
//Posting user data to script
JSONObject json = jsonParser.makeHttpRequest(
SEARCH_URL, "POST", params);
// full json response
Log.d("Search attempt", json.toString());
// json success element
success = json.getInt(TAG_SUCCESS);
if (success == 1) {
Log.d("Successful Search!", json.toString());
//save search data
mCommentList = new ArrayList<HashMap<String, String>>();
mComments = json.getJSONArray(TAG_POSTS);
// JSONArray mComments = new JSONArray(TAG_POSTS);
// looping through all posts according to the json object returned
for (int i = 0; i < mComments.length(); i++) {
JSONArray innerArray = mComments.optJSONArray(i);
for (int j = 0; j < innerArray.length(); j++) {
JSONObject c = innerArray.getJSONObject(j);
//gets the content of each tag
String title = c.getString(TAG_TITLE);
String address = c.getString(TAG_ADDRESS);
String brand = c.getString(TAG_BRAND);
String company = c.getString(TAG_COMPANY);
String id = c.getString(TAG_ID);
//so our JSON data is up to date same with our array list
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_TITLE, title);
map.put(TAG_ADDRESS, address);
map.put(TAG_BRAND, brand);
map.put(TAG_COMPANY, company);
map.put(TAG_ID, id);
mCommentList.add(map);
}
}
Intent r = new Intent(Search.this, Results.class);
//either
//r.putExtra("arraylist", mCommentList);
// startActivityForResult(r, 5000);
//or
r.putExtra("searchquery", searchquery);
startActivity(r);
return json.getString(TAG_MESSAGE);
}else{
Log.d("Invalid Search!", json.toString());
return json.getString(TAG_MESSAGE);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;

Android -php-mysql- JSON connection issue

I imported the androidhive project(http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/) and I added another table to the database. The details of the second table are displayed in the second listview. After clicking on listview item the edit page is displayed. But I didn't get the second table details in the corresponding edittexts.
Here are my java classes:

I've seen sample code from other posts, but I don't quite understand how to apply it. Can you please give me sample code?

PHP CODE
//you need add single quote near $pid
$result = mysql_query("SELECT *FROM penjualan WHERE pid = '$pid'");
For your java code :
public class Penjualan1 extends Activity {
// All xml labels
String pid;
TextView mejaTv;
TextView customerTv;
TextView keteranganTv;
// Progress Dialog
private ProgressDialog pDialog;
// Creating JSON Parser object
JSONParser jsonParser = new JSONParser();
// Profile JSON url
private static final String url_order_detials = "-my url-/get_penjualan_details.php";
// ALL JSON node names
private static final String TAG_PRODUCT = "product";
private static final String TAG_SUCCESS = "success";
private static final String TAG_GET = "get";
private static final String TAG_MEJA = "meja";
private static final String TAG_CUST = "customer";
private static final String TAG_KET = "keterangan";
String sMeja, sCustomer, sKeterangan; //Declare a variable to handle your data.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.f_penjualan1);
mejaTv = (TextView) findViewById(R.id.meja);
customerTv = (TextView) findViewById(R.id.customer);
keteranganTv = (TextView) findViewById(R.id.keterangan);
// Loading Profile in Background Thread
new GetProductDetails().execute();
}
/**
* Background Async Task to Get complete product details
* */
class GetProductDetails extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Penjualan1.this);
pDialog.setMessage("Loading product details. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/**
* Getting product details in background thread
* */
protected String doInBackground(String... params) {
// Check for success tag
// TODO Auto-generated method stub
int success;
try {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("pid", pid));
// getting product details by making HTTP request
// Note that product details url will use GET request
JSONObject json = jsonParser.makeHttpRequest(
url_order_detials, "GET", params);
// check your log for json response
Log.d("Single Product Details", json.toString());
// json success tag
success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully received product details
JSONArray productObj = json
.getJSONArray(TAG_GET); // JSON Array
// get first product object from JSON Array
JSONObject product = productObj.getJSONObject(0);
// product with this pid found
// Edit Text
// display product data in EditText
sMeja = product.getString(TAG_MEJA);
sCustomer = product.getString(TAG_CUST);
sKeterangan = product.getString(TAG_KET);
}else{
// product with pid not found
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
mejaTv.setText(sMeja);
customerTv.setText(sCustomer);
keteranganTv.setText(sKeterangan);
}
});
// dismiss the dialog once got all details
pDialog.dismiss();
}
}
}
Done.. :D

I m trying to create an application using eclipse. in the user-register page , after I entered all the required data, and click the submit button, the message " Unfortunately, your eclipse has been stopped". what does this message means and how to solve it?

Change the comparision method to equals() instead of contentEquals() in your code
as The String#equals() not only compares the String's contents, but also checks if the other object is also an instance of a String. The String#contentEquals() methods only compares the contents (the character sequence) and does not check if the other object is also an instance of String. It can be anything as long as it is an implementation of CharSequence or an instance of StringBuffer.
So change your code as like this
if(name.equals("")||username.equals("")||email.equals("")||password.equals(""))
{
....
}
