private static JSONObject jObj = null;
private static String json = "";
JSONParser() {

JSONObject getJSONFromUrl(String url) {
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} 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) {
// Log.i("Tag",line);
sb.append(line).append("\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer_Error", "Error converting result " + e.toString());
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON_Parser", "Error parsing data " + e.toString());
}
return jObj;
}
ini source code MainActivitynya:
protected String doInBackground(String... arg0) {
JSONParser jParser = new JSONParser();
JSONObject json = jParser.getJSONFromUrl(url);
try {
// if (json.getString(success) != null) {
// Log.e("error", "nilai sukses=" + success);
// }
success = json.getString(success);
Log.e("error", "nilai sukses=" + success);
JSONArray hasil = json.getJSONArray("login");
if (success.equals(1)) {
//if (Integer.parseInt("success") == 1){
for (int i = 0; i < hasil.length(); i++) {
JSONObject c = hasil.getJSONObject(i);
String username = c.getString("username").trim();
String name = c.getString("name").trim();
session.createLoginSession(username, name);
Log.e("ok", "ambil data");
}
// Log.e("error", "Ya ambil data ok");}
