copied!<p>I have an async task which fetches a file from my server. it takes long before it starts but when it starts it is fast. on mobile its is done in about 5 seconds while on wifi i can wait for 40seconds+. </p> <p>this is the asynctask: public class ProgressTask extends AsyncTask { @Override</p> <pre><code>protected Void doInBackground(String... params) { // in background for (int i = 0; i < selectedWidgets.size(); i++) { saveWidget(selectedWidgets.get(i)); } } return null; } } </code></pre> <p>so it starts savewidget. savewidget = download file and store it local</p> <p>here is the savewidget:</p> <pre><code>public void saveWidget(int widgetnumber) { try { // set location and name File root = new File(Environment.getExternalStorageDirectory(), "widgets"); jsonPath = root.getAbsolutePath() + "/widget"; File gpxfile = new File(root, "widget" + widgetnumber + ".txt"); if (!gpxfile.exists()) { // if file doesn't excists, get it from the internet HttpParams httpParameters = new BasicHttpParams(); // add extra time to get it before error is thrown HttpConnectionParams.setConnectionTimeout(httpParameters, 0); HttpConnectionParams.setSoTimeout(httpParameters, 0); HttpConnectionParams.setTcpNoDelay(httpParameters, true); DefaultHttpClient httpclient = new DefaultHttpClient( httpParameters); // set everyting to get it from the internet link = "http://somestuff/widget_id=" + widgetnumber; HttpPost httppost = new HttpPost(link); InputStream inputStream = null; String result = null; BufferedReader reader = null; // set response HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); inputStream = entity.getContent(); // read and save it reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8); StringBuilder sb = new StringBuilder(); String line = null; try { while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } } catch (IOException e2) { e2.printStackTrace(); } result = sb.toString(); // code is in app if (!root.exists()) { root.mkdirs(); } // write it to new file FileWriter writer = new FileWriter(gpxfile); writer.append(result); writer.flush(); writer.close(); } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } </code></pre> <p>anyone who can explain why it needs so much time just to fetch a small over wifi and it goes fast over mobile internet? i'm kinda clueless atm.</p> <p>is this a good way or is there a better?</p> <p>maybe not bad to mention, at some point i use multipartentity in a service to send a video and data to the server. it works but just like this it is slow. once the first video is uploaded it goes fast.</p> <p>multipartentity to send video:</p> <pre><code>public Void SendToServer(String aUrl, String file, String parameters, String uuid, String uploaded, int id) { // set extra settings for upload HttpParams params = new BasicHttpParams(); HttpConnectionParams.setConnectionTimeout(params, 0); HttpConnectionParams.setSoTimeout(params, 0); HttpConnectionParams.setTcpNoDelay(params, true); params.setParameter(CoreProtocolPNames.WAIT_FOR_CONTINUE, HttpVersion.HTTP_1_1); // add thes settings HttpClient httpClient = new DefaultHttpClient(params); // set uploadlocation HttpPost httpPost = new HttpPost(aUrl); try { jsonParameters = new JSONObject(parameters); } catch (JSONException e2) { // TODO Auto-generated catch block e2.printStackTrace(); stopSelf(); } // set video FileBody fb = new FileBody(new File(file)); // get extra parameters from json and add them to entity try { MultipartEntity entity = new MultipartEntity( HttpMultipartMode.STRICT); Iterator<String> iter = jsonParameters.keys(); // loop as long as there are keys while (iter.hasNext()) { String key = iter.next(); try { value = jsonParameters.get(key); } catch (JSONException e) { // Something went wrong! stopSelf(); } // add them entity.addPart(key, new StringBody(value.toString())); } // continue to add data to entity entity.addPart("widget_uuid", new StringBody(uuid)); entity.addPart("widget_uploaded", new StringBody(uploaded)); entity.addPart("file", fb); httpPost.setEntity(entity); // get response from server HttpResponse response = httpClient.execute(httpPost); try { // get statuscode from server HttpEntity resEntity = response.getEntity(); String serverRespons = ""; if (serverRespons != null) { serverRespons = EntityUtils.toString(resEntity); } serverRespons = serverRespons.substring( serverRespons.indexOf("(") + 1, serverRespons.indexOf(")")); try { jsonServerRespons = new JSONObject(serverRespons); } catch (JSONException e) { } try { statusServerRespons = jsonServerRespons.getString("status"); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } Log.i("test", statusServerRespons); // delete successfully sended video's if (statusServerRespons.equalsIgnoreCase("ok")) { vds.deleteTitle(id); } } catch (ClientProtocolException e1) { // Something went wrong! stopSelf(); } catch (IOException e1) { // Something went wrong! stopSelf(); } return null; } catch (IOException e) { // Something went wrong! stopSelf(); } return null; } </code></pre> <p>thanks in advance </p>
