Answer 1

Behold the JSONObject, which reads Strings and will let you pull pieces out by name.

Answer 2

I would suggest you to use Gson to parse json strings. Read this tutorial

Answer 3

Here:

final URL url = new URL(path);
InputStream is = url.openStream();

final String jString = convertStreamToString(is);
final JSONObject jObject = new JSONObject(jString);

final String jString = convertStreamToString(is);

final JSONObject jObject = new JSONObject(jString);

long personId = jObject.getLong("idpersonne");
String nom = jObject.getString("nom");
String prenom = jObject.getString("prenom");

convertStreamToString method:

private String convertStreamToString(final InputStream is)
    {

        final BufferedReader reader = new BufferedReader(new InputStreamReader(is));

        final StringBuilder stringBuilder = new StringBuilder();

        String line = null;
        try
        {
            while ((line = reader.readLine()) != null)
            {
                stringBuilder.append(line + "\n");
            }
        } catch (final IOException e)
        {
            L.e(e.getMessage());

        } finally
        {
            try
            {
                is.close();

            } catch (final IOException e)
            {

                L.e(e.getMessage());
            }
        }
        return stringBuilder.toString();
    }
