Displaying database records in android using JAVA RESTful webservice

I am trying to display database record using java restful web service. I have able to create a login form using it but I cannot display the records on the database. I tried this code but its not working at all. When button is pressed nothing happens. Heres my code.
DriverDetails.java
class Details extends Activity {
TextView name1;
TextView plate1;
Button Btngetdata;
//URL to get JSON Array
private static String url = "http://192.168.254.108:8080/taxisafe/display/taxidetails";
//JSON Node Names
private static final String TAG_USER = "taxi";
private static final String TAG_NAME = "taxi_name";
private static final String TAG_EMAIL = "taxi_plate_no";
JSONArray user = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Btngetdata = (Button)findViewById(R.id.getdata);
Btngetdata.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
new JSONParse().execute();
}
});
}
private class JSONParse extends AsyncTask<String, String, JSONObject> {
#Override
protected void onPreExecute() {
super.onPreExecute();
name1 = (TextView)findViewById(R.id.name);
plate1 = (TextView)findViewById(R.id.plate);
}
#Override
protected JSONObject doInBackground(String... args) {
HttpConnection jParser = new HttpConnection();
// Getting JSON from URL
JSONObject json = jParser.getJSONFromUrl(url);
return json;
}
#Override
protected void onPostExecute(JSONObject json) {
try {
// Getting JSON Array
user = json.getJSONArray(TAG_USER);
JSONObject c = user.getJSONObject(0);
// Storing JSON item in a Variable
String name = c.getString(TAG_NAME);
String email = c.getString(TAG_EMAIL);
//Set JSON Data in TextView
name1.setText(name);
plate1.setText(email);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
HttpConnection.java
public class HttpConnection {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public HttpConnection() {
}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}

I suggest adding Volley to your project
https://developer.android.com/training/volley/index.html
and following the example here https://developer.android.com/training/volley/request.html#request-json
You will not need to create your own HTTP request. Let Volley handle the network request using JSONObjectRequest

and I'm try to give success a string like :

But it didnt Works.. it give this statement error has activated on my code :

}
});
I have no idea. Pls Help ..
thanks So Much ...

Looks like this line might be returning null, if String success = "" didn't work:
success = json.getString("success");
Have you inspected the JSON that you are parsing and verified that the "success" field is where you expect and properly formatted?

Agree with #ρяσѕρєя K
There was cast exception occurred that means you need to use JSON Array. Coz you are using JSON Object where actually JSON Array is required.
If you are confused within response which is receiving is JSONArray or JSONObject then you can go for get() method which return data in Object manner.
example : Object c = details.get(i);
So after that you can check for
If(c instanceOf JSONArray){
/// perform as array operation
}
If(c instanceOf JSONObject){
// perform json object retrieving operation
}

JSON: Value of type java.lang.String cannot be converted to JSONObject

I'm trying to program an app to send a String to a service. A friend of mine has a service to receive the data.

I read questions to other people with the same problem. The solution seemed to be to add a "{" at the beginning of the json String and a "}" at the end, but it didn't work to me. I tried changing this:
String json = serviceClient.makeServiceCall(URL_NEW_PREDICTION,
ServiceHandler.POST, params);
to this:
String json = "{" + serviceClient.makeServiceCall(URL_NEW_PREDICTION,
ServiceHandler.POST, params) + "}";
but the I got this error:
"org.json.JSONException: Expected ':' after FIRST at character 9 of {FIRST DATA New record created successfully}"

You're receiving back a string that is not able to be parsed to JSON. You can't just make something JSON by adding braces, it needs to adhere to proper JSON formatting. This site shows some good examples of what that means.
Specifically, the parser is telling you that having a space after FIRST isn't okay without having quotes around it...but just adding that won't fix the issue, the problem is more deep than that.

Error when parsing json result from http post on android app

I have a php script that returns this json array.
{"PID":"1","PName":"Guitar","Brand":"Fender","Price":"110","Cat#":"1","Typ#":"1"}
I am making a simple app that places these results into several text views. only one product is returned each time as above.
when I run the app I get this Error: org.json.JSONException: Value

Any help would be greatly appreciated.

That's not an array it's an object
JSONObject jObject = new JSONObject(result);
String anem = jObject.getString("PName");
tvname.setText(anem);

{"Typ#":"1","Brand":"test","Cat#":"1","PName":"Test","PID":"2","Price":"120"} of type org.json.JSONObject cannot be converted to JSONArray.
You are trying to convert a JSONObject into a JSONArray, this is your error.
Use :
JSONOjbect jso = new JSONObject(result);
A JSONObject Start with { and end with }.
A JSONArray Start with [ and end with ].
