copied!<p>with the code you posted there doesn't seem to have anything that would be taking an awful a lot of time. </p> <p>I don't believe making an endless list (either using the endless adapter or manually) is the case for you because apparently the web-server you're communicating with does not have the options for page (e.g. when on the URL you specific items per page and page number like this: <code>?per_page=20&page_no=1</code>) and those type of list only makes sense for such.</p> <p>Just as a simple test, put those lines before after your code:</p> <pre><code>long now = System.currentTimeMillis(); JSONObject json = jParser.makeHttpRequest(url_all_ads, "POST", params); Log.d("Test", "Elapsed time is: " + Long.toString(System.currentTimeMillis() - now)); </code></pre> <p>then you can check on your LogCat how long did it took to make the http request.</p> <p><strong>edit:</strong></p> <p>suggested alternative to HashMap<> as I don't believe they are very efficient ways of storing data.</p> <pre><code>public class MyData(){ JSONObject data; public MyData(JSONObject data){ this.data=data; } public String getId(){ return data.getString("rowid"); } // repeat for the other info you need, also override the toString to return the data.toString(); } </code></pre> <p>that way all the JSON parsing will be done at a later point in time and in small batches and your for loop would be as simple as:</p> <pre><code> for (int i = 0; i < dataJsonArray.length(); i++) { productList.add(new MyData(dataJsonArray.getJSONObject(i)); } </code></pre>
