    <p>you can send the data as Json packets to the device and in device parse the json packets and access the data. your calls to webservice should be a http call eg this is for the client.</p> <p>http:\server\metnod\get_somedata?name=something</p> <p>and the server should query the database for this parameter and send you the reponse as Json. parse json and get your details.</p> <pre><code>String url = "http:\\example.com\mycontroller\get_employee?id=2" HttpPost httpPostRequest = new HttpPost(url); StringEntity se; se = new StringEntity(jsonObjSend.toString()); httpPostRequest.setEntity(se); httpPostRequest.setHeader("Authorization", usercredential); httpPostRequest.setHeader("Accept", "application/json"); httpPostRequest.setHeader("Content-type", "application/json"); long t = System.currentTimeMillis(); response = (HttpResponse) httpclient.execute(httpPostRequest); Log.i(TAG, "HTTPResponse received in [" + (System.currentTimeMillis()-t) + "ms]"); HttpEntity entity = response.getEntity(); if (entity != null) { InputStream instream = entity.getContent(); Header contentEncoding = response.getFirstHeader("Content-Encoding"); if (contentEncoding != null &amp;&amp; contentEncoding.getValue().equalsIgnoreCase("gzip")) { instream = new GZIPInputStream(instream); } // convert content stream to a String String resultString= convertStreamToString(instream); Log.v(null, "resultString "+resultString); instream.close(); // Transform the String into a JSONObject if(resultString!=null){ jsonObjRecv = new JSONObject(resultString); } // Raw DEBUG output of our received JSON object: Log.i(TAG,"&lt;jsonobject&gt;\n"+jsonObjRecv.toString()+"\n&lt;/jsonobject&gt;"); return jsonObjRecv; </code></pre> <p>In the server side you should have a get_employee method in a controller called mycontroller. in the method you can process the request as a normal http request and send the response as json eg</p> <pre><code>employee = Employee.find_by_id(params[:id]) @js_response = ActiveSupport::JSON.encode(employee) respond_to do |format| format.json { render :json =&gt; @js_response} format.html end </code></pre> <p>for CRUD you need to create different methods with appropriate parameters like delete_employee, update_employee etc. refer json.org to create/parse json in android</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
