Use below code for get json from any server

class MyAsyncTask extends AsyncTask<String, String, Void> {
		private ProgressDialog progressDialog = new ProgressDialog(context);
		InputStream inputStream = null;
		String result = "";
		protected void onPreExecute() {
			progressDialog.setMessage("Please wait downloading your data...");
			progressDialog.show();
			progressDialog.setOnCancelListener(new OnCancelListener() {
				public void onCancel(DialogInterface arg0) {
					MyAsyncTask.this.cancel(true);
				}
			});
		}
		@Override
		protected Void doInBackground(String... params) {
			// set your url of json file
			String url_select = "http://yoururlhere.com";
			ArrayList<NameValuePair> param = new ArrayList<NameValuePair>();
			try {
				// Set up HTTP post
				// HttpClient is more then less deprecated. Need to change to
				// URLConnection
				HttpClient httpClient = new DefaultHttpClient();
				HttpPost httpPost = new HttpPost(url_select);
				httpPost.setEntity(new UrlEncodedFormEntity(param));
				HttpResponse httpResponse = httpClient.execute(httpPost);
				HttpEntity httpEntity = httpResponse.getEntity();
				// Read content & Log
				inputStream = httpEntity.getContent();
			} catch (Exception e4) {
				e4.printStackTrace();
			}
			// Convert response to string using String Builder
			try {
				BufferedReader bReader = new BufferedReader(
						new InputStreamReader(inputStream, "utf-8"), 8);
				StringBuilder sBuilder = new StringBuilder();
				String line = null;
				while ((line = bReader.readLine()) != null) {
					sBuilder.append(line + "\n");
				}
				inputStream.close();
				result = sBuilder.toString();
			} catch (Exception e) {
			}
			return null;
		} // protected Void doInBackground(S
		protected void onPostExecute(Void v) {
			// parse JSON data
			try {
				JSONArray jArray = new JSONArray(result);
				for (int i = 0; i < jArray.length(); i++) {
					JSONObject jObject = jArray.getJSONObject(i);
					String name = jObject.getString("name");
					String tab1_text = jObject.getString("tab1_text");
					int active = jObject.getInt("active");
				} // End Loop
				this.progressDialog.dismiss();
			}  catch (Exception e)
		} // protected void onPostExecute(Void v)
	} // class MyAsync
