So it looks like your trying to connect to a server.... What remote
web services are you using.
For a scanner project I created last semester, I used XAMPP
locally(just to see code work correctly), then I used Teamviewer when
I went live.
On the remote server file, I placed a php file with the JSON object to
reference in the android code. Your code looks fine, however, I've
learn it's not just this code that you may need. I connected my code
using a button called my SQL... I'll post the code below... hope this
helps...
Also, something I didn't find out until the end, but make sure your
server PHP and code are up to date...I ran into a last minute issue I
had to correct on the server side...
This is the button code (click button, sends data to mySQL server from
anywhere)
case R.id.buttonSQL1:
try {
JSONObject json = new JSONObject();
json.put("barcode", mbarcodeEdit.getText());
json.put("description", description.getText());
json.put("make", make.getText());
json.put("serial", serial.getText());
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams,
TIMEOUT_MILLISEC);
HttpClient client = new
DefaultHttpClient(httpParams);
String url =
"http://10.0.2.2:8080/webservice4.php";; //
needed for the php file pass over
HttpPost request = new HttpPost(url);
request.setEntity(new
ByteArrayEntity(json.toString().getBytes(
"UTF8")));
request.setHeader("json", json.toString());
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity,
there is no
need
if (entity != null) {
InputStream instream =
entity.getContent();
String result =
RestClient.convertStreamToString(instream);
Log.i("Read from server", result);
Toast.makeText(this, result,
Toast.LENGTH_LONG).show();
}
} catch (Throwable t) {
Toast.makeText(this, "Request failed: " +
t.toString(),
Toast.LENGTH_LONG).show();
}
// showDialog(DIALOG_ID);
break;
}
}
Also you need to insert this code (a separate java file called
RestClient)
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.util.Log;
public class RestClient {
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();
}
public static void connect(String url)
{
HttpClient httpclient = new DefaultHttpClient();
// Prepare a request object
HttpGet httpget = new HttpGet(url);
// Execute the request
HttpResponse response;
try {
response = httpclient.execute(httpget);
// Examine the response status
Log.i("Praeda",response.getStatusLine().toString());
// Get hold of the response entity
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no
need
// to worry about connection release
if (entity != null) {
// A Simple JSON Response Read
InputStream instream = entity.getContent();
String result= convertStreamToString(instream);
Log.i("Praeda",result);
// A Simple JSONObject Creation
JSONObject json=new JSONObject(result);
Log.i("Praeda","<jsonobject>\n"+json.toString()+"\n</
jsonobject>");
// A Simple JSONObject Parsing
JSONArray nameArray=json.names();
JSONArray valArray=json.toJSONArray(nameArray);
for(int i=0;i<valArray.length();i++)
{
Log.i("Praeda","<jsonname"+i+">
\n"+nameArray.getString(i)+"\n</jsonname"+i+">\n"
+"<jsonvalue"+i+">\n"+valArray.getString(i)
+"\n</jsonvalue"+i+">");
}
// A Simple JSONObject Value Pushing
json.put("sample key", "sample value");
Log.i("Praeda","<jsonobject>\n"+json.toString()+"\n</
jsonobject>");
// Closing the input stream will trigger connection
release
instream.close();
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Remember to add your permissions in you xml Manifest file...
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission
android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" /
>
Here's an example of the PHP code I placed on my server...
<?php
$json = file_get_contents('php://input');
$obj = json_decode($json);
//echo $json;
$con = mysql_connect('localhost','Username','password') or die
('Cannot connect to the DB');
mysql_select_db('tlmcqueen',$con);
/* grab the posts from the db */
//$query = "SELECT post_title, guid FROM wp_posts WHERE post_author
= $user_id AND post_status = 'publish' ORDER BY ID DESC LIMIT
$number_of_posts";
mysql_query("INSERT INTO `databasename`.`assets` (barcode,
description, make, serial)
VALUES ('".$obj->{'barcode'}."', '".$obj->{'description'}."','".$obj-
>{'make'}."','".$obj->{'serial'}."')");
mysql_close($con);
//
//$posts = array($json);
$posts = array(1);
header('Content-type: application/json');
echo json_encode(array('posts'=>$posts));
?>
