This is my AsyncTask class:
public class JSONParser extends AsyncTask {
public interface MyCallbackInterface {
public void onRequestComplete(JSONObject result);
}
private MyCallbackInterface mCallback;
public JSONParser(MyCallbackInterface callback) {
mCallback = callback;
Context context = (Context) callback;
}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpPost = new HttpGet(url);
HttpResponse getResponse = null;
final HttpParams httpParameters = httpClient.getParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, 10 * 10000);
HttpConnectionParams.setSoTimeout (httpParameters, 10 * 10000);
try {
getResponse = httpClient.execute(httpPost);
} catch (ClientProtocolException e2) {
e2.printStackTrace();
} catch (IOException e2) {
e2.printStackTrace();
}
final int statusCode = getResponse.getStatusLine().getStatusCode();
if (statusCode != HttpStatus.SC_OK) {
Log.w(getClass().getSimpleName(),
"Error " + statusCode + " for URL " + url);
return null;
}
HttpEntity getResponseEntity = getResponse.getEntity();
String json = null;
try {
json = EntityUtils.toString(getResponseEntity);
} catch (ParseException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
JSONObject jObj = null;
// 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;
}
@Override
protected JSONObject doInBackground(String... params) {
String url = params[0];
return getJSONFromUrl(url);
}
@Override
protected void onPostExecute(JSONObject result) {
mCallback.onRequestComplete(result);
}
}
I get the JSON answer in UI (in class RegisterActivity extends Activity implements MyCallbackInterface) with:
public class RegisterActivity extends Activity implements MyCallbackInterface{
...
@Override
public void onRequestComplete(JSONObject json) {
//hire parse and display json
...
I call JSONParser from the same UI (class RegisterActivity extends Activity implements MyCallbackInterface)
JSONParser mJSONParser1 = new JSONParser(context111);
mJSONParser1.execute(SERVER_URL+"?method=registration&user="+user+"&pass="+pass+"®Id="+regId);
