Hello everyone I have been implementing gcm but the problem is that it is not receiving the notification and I have tried both sending gcm message from my project web server and tried to implement it on android but still it doesn't worked, it is generating the token id properly but it doesn't receive any message , following is my classes I have used for implementing gcm
GcmServiceListner.class
public class GcmServiceListner extends GcmListenerService {
private static final String TAG = "MyGcmListenerService";
private PreferencesHandler ph;
@Override
public void onMessageSent(String msgId) {
super.onMessageSent(msgId);
Log.e("Anas", "MESSAGE SENT");
}
@Override
public void onMessageReceived(String from, Bundle data) {
try {
ph = new PreferencesHandler(this);
int notiNum = ph.getChatNotificationNumberName();
notiNum++;
ph.setChatNotificationNumberName(notiNum);
String message = data.getString("data");
Log.d(TAG, "From: " + from);
Log.d(TAG, "Message: " + message);
if (from.startsWith("/topics/")) {
// message received from some topic.
} else {
// normal downstream message.
}
// [START_EXCLUDE]
/**
* Production applications would usually process the message here.
* Eg: - Syncing with server.
* - Store message in local database.
* - Update UI.
*/
/**
* In some cases it may be useful to show a notification indicating to the user
* that a message was received.
*/
sendNotification(message);
} catch (Exception e) {
e.printStackTrace();
}
// [END_EXCLUDE]
}
// [END receive_message]
/**
* Create and show a simple notification containing the received GCM message.
*
* @param message GCM message received.
*/
private void sendNotification(String message) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_media_pause)
.setContentTitle("GCM Message")
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
As you can see I have override the method of onMessageSend it calls when I have been implementing to send the message from within the app, it calls this method after few minutes when I have send the message through gcm but still onMessageReceived method doesn't works, following is the code when I m calling the send function from the app
gcm = GoogleCloudMessaging.getInstance(this);
new AsyncTask<Void, Void, String>() {
@Override
protected String doInBackground(Void... params) {
String msg = "";
Log.e(TAG,"upstream");
try {
Bundle data = new Bundle();
data.putString("data", "Hello World");
String id = SENDING_ID;
gcm.send(to+"@gcm.googleapis.com", id, data);
msg = "Sent message";
} catch (IOException ex) {
msg = "Error :" + ex.getMessage();
}
return msg;
}
@Override
protected void onPostExecute(String msg) {
Log.e(TAG, msg + " msg");
}
}.execute();
"to" over is the token id where I have to send the message and "SENDING_ID" is the ID generated from google server
Now the following is the code of the php of my web server where I am implementing the gcm sending code
define( 'API_ACCESS_KEY', API_KEY );
$fields = array(
'to' => TOKEN_ID,
'data' => "TEST MESSAGE",
);
$headers = array(
'Authorization: key='.API_KEY,
'Content-Type: application/json'
);
echo json_encode($fields);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL,"https://gcm-http.googleapis.com/gcm/send");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false);
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
echo "ERROR IN CURL";
}else{
echo "ERROR FREE CURL";
}
Please help me out what I have to do now :-)
