I have created and array list which will fetch into an sqlite db inside

Answer 1

You can make use of JSON or XML for sending data from android to php server. On the PHP side, all you need is the built-in json_decode, which will deserialize your json and return an object or an associative array.

Answer 2

For that you have to post your data on php server, then fetch that data and store into your database .

Here i attach one example which send data on server and getting response in json .

                    HttpPost postMethod = new HttpPost("Your Url");
                    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();


                    // test is a one array list

                    for(int i=0;i<test.size();i++)
                    {
                        nameValuePairs.add(new BasicNameValuePair("sample[]", Integer.toString(test.get(i))));
                    }

                    postMethod.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                    DefaultHttpClient hc = new DefaultHttpClient();

                    HttpResponse response = hc.execute(postMethod);
                    HttpEntity entity = response.getEntity();

                    // If the response does not enclose an entity, there is no need
                    // to worry about connection release

                    if (entity != null) 
                    {
                        InputStream inStream = entity.getContent();
                        result= convertStreamToString(inStream);
                        jsonObject = new JSONObject(result);
                        responseHandler.sendEmptyMessage(0);
                    }
                }
                catch(Exception e)
                {
                    e.printStackTrace();
                }
            }
        }.start();

Here sample[] is a field in which i assign array value to send on server . From server side you have to fetch the sample[] field .

public static String convertStreamToString(InputStream is)
{
   BufferedReader reader = new BufferedReader(new InputStreamReader(is));
   StringBuilder sb = new StringBuilder();

   String line = null;
   try 
   {
       while ((line = reader.readLine()) != null) 
       {
           sb.append(line + "\n");
       }
   } 
   catch (IOException e) 
   {
       e.printStackTrace();
   } 
   finally 
   {
       try 
       {
           is.close();
       } 
       catch (IOException e) 
       {
           e.printStackTrace();
       }
   }
   return sb.toString();
