i already coding an ac2dm application, i follow this tutorial,
but... i found something strange with the code... here's the code..
package de.vogella.android.c2dm.simpleclient;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.preference.PreferenceManager;
import android.provider.Settings.Secure;
import android.util.Log;
public class C2DMRegistrationReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Log.w("C2DM", "Registration Receiver called");
if ("com.google.android.c2dm.intent.REGISTRATION".equals(action)) {
Log.w("C2DM", "Received registration ID");
final String registrationId = intent
.getStringExtra("registration_id");
String error = intent.getStringExtra("error");
Log.d("C2DM", "dmControl: registrationId = " + registrationId
+ ", error = " + error);
String deviceId = Secure.getString(context.getContentResolver(),
Secure.ANDROID_ID);
createNotification(context, registrationId);
sendRegistrationIdToServer(deviceId, registrationId);
// Also save it in the preference to be able to show it later
saveRegistrationId(context, registrationId);
}
}
private void saveRegistrationId(Context context, String registrationId) {
SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(context);
Editor edit = prefs.edit();
edit.putString(C2DMClientActivity.AUTH, registrationId);
edit.commit();
}
public void createNotification(Context context, String registrationId) {
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
"Registration successful", System.currentTimeMillis());
// Hide the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Intent intent = new Intent(context, RegistrationResultActivity.class);
intent.putExtra("registration_id", registrationId);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
notification.setLatestEventInfo(context, "Registration",
"Successfully registered", pendingIntent);
notificationManager.notify(0, notification);
}
// Incorrect usage as the receiver may be canceled at any time
// do this in an service and in an own thread
public void sendRegistrationIdToServer(String deviceId,
String registrationId) {
Log.d("C2DM", "Sending registration ID to my application server");
HttpClient client = new DefaultHttpClient();
**HttpPost post = new HttpPost("http://vogellac2dm.appspot.com/register");**
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
// Get the deviceID
nameValuePairs.add(new BasicNameValuePair("deviceid", deviceId));
nameValuePairs.add(new BasicNameValuePair("registrationid",
registrationId));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String line = "";
while ((line = rd.readLine()) != null) {
Log.e("HttpResponse", line);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
Look at this pary HttpPost post = new HttpPost("http://vogellac2dm.appspot.com/register");

This is the php code...

Push Notification
<form action="./send_notification.php" method="get" enctype="application/x-www-form-urlencoded" name="Send Notification" target="_self">
<label>Push Message
<input name="message" type="text" size="50" maxlength="50"></label>
<input name="Send Message" type="submit" value="Send Message">
</form>
<?php $sucess;?>
And then, when i try to send, i get a notification, but sometimes the content not same with what i sent...
example, first i send a message "Tes percobaan", on my device i get "Tes percobaan", but if i sent it again with a message "percobaaan" i get a notification on my device, but the content is "Tes percobaan" <-- the content before
so any suggestion here??
