Question

I am new to android. I have a url which only has the json format. Suppose the url is- http://www.example.com/filter… This url contains only json format data. Take for example this link contains following material: – [ {u:”user”,s:”male” image:”hello.jpg”}]
The link contains only the above data. Now, I want to test the connection in my android i.e.whether i am able to connect to the values of parameter u. I created a http client and tried to parse the json format. The program but does not display anything.. Here’s what i did

HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.example.com/filter");

    try
    {
        HttpResponse response = httpclient.execute(httppost);
        InputStream in = response.getEntity().getContent();

byte [] buffer = new byte[in.available()];
        while (in.read(buffer) != -1);
        String jsontext = new String(buffer);
        JSONArray entries = new JSONArray(jsontext);
for (i=0;i<entries.length();i++)
        {
            JSONObject post = entries.getJSONObject(i);
            if(post.getString("u")=="driver")
            {
            x="Success";
            }
        }

        txtResult.setText(x); // x is string
    }

I just want to test my connection. Please help!

Answer 1

Your JSON is invalid. Keys have to be quoted:

[{"u": "user", "s": "male", "image": "hello.jpg"}]

It might be valid JavaScript, but it’s not valid JSON.

You might also want to look in logcat and post any exceptions that occur (I’m sure you get an invalid JSON exception somewhere).
