我正在实现一个向 PHP 服务器发送消息的 Android 应用程序，然后生成 GCM 推送通知的 PHP 服务器将其定向到相关的注册 ID。问题是尽管 GCMIntentService 类收到了消息，但未显示通知，如附加的日志 cat 中所示

这是Android代码

public class GCMIntentService extends GCMBaseIntentService {

private static final String TAG = "===GCMIntentService===";
private static final String senderId = "*****";
String message;

public GCMIntentService() {
    super(senderId);
}

static void displayMessage(Context context, String message) {
    Intent intent = new Intent("guc.edu.iremote.DISPLAY_MESSAGE");
    intent.putExtra("message", message);
    context.sendBroadcast(intent);
}

@Override
protected void onRegistered(Context arg0, String registrationId) {
    Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
    // sets the app name in the intent
    registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
    registrationIntent.putExtra("sender", senderId);
    startService(registrationIntent);
    Log.i(TAG, "Device registered: regId = " + registrationId);
    displayMessage(getApplicationContext(), "Your device registred with GCM");

}


@Override
protected void onUnregistered(Context arg0, String arg1) {
    Intent unregIntent = new Intent("com.google.android.c2dm.intent.UNREGISTER");
    unregIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
    startService(unregIntent);
    Log.i(TAG, "unregistered = " + arg1);
     displayMessage(getApplicationContext(), "Unregistered");

}

@Override
protected void onMessage(Context context, Intent intent) {
    message = intent.getStringExtra( "message" );
     // message = intent.getExtras().getString("message");

  Intent notificationIntent=new     Intent(context,this.getApplicationContext().getClass());
  PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
  WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |     PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
  wl.acquire();
  displayMessage(context, message);
 generateNotification(context, message, notificationIntent);

final AlertDialog.Builder d = new AlertDialog.Builder(context);
//Use an activity object here
 d.setMessage(message) //Provide a message here... A string or a string ID will do
 .setCancelable(false) //If you want them to be able to dismiss with a Back button
 .setPositiveButton(R.drawable.navigationaccept, new DialogInterface.OnClickListener()     {
     AlertDialog dialog = d.create();
    public void onClick(DialogInterface dialog, int which) {
        // TODO Auto-generated method stub
        dialog.dismiss();


    }
}) 

 .create()
 .show();


}



@SuppressWarnings("deprecation")
private static void generateNotification(Context context, String message, Intent notificationIntent) {
     int icon = R.drawable.ic_launcher;
     long when = System.currentTimeMillis();


     NotificationManager notificationManager = (NotificationManager)
             context.getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    notificationManager.notify(0, notification);

     String title = context.getString(R.string.app_name);
     // set intent so it does not start a new activity
     notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
             Intent.FLAG_ACTIVITY_SINGLE_TOP);
     PendingIntent intent =PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
     notification.setLatestEventInfo(context, title, message, intent);
     notification.flags |= Notification.FLAG_AUTO_CANCEL;
     notificationManager.notify(0, notification);
    notification.defaults |= Notification.DEFAULT_SOUND;
   notification.defaults |= Notification.DEFAULT_VIBRATE;
  notification.ledARGB = 0xff00ff00;
 notification.ledOnMS = 300;
 notification.ledOffMS = 1000;
 notification.flags |= Notification.FLAG_SHOW_LIGHTS;
 }

@Override
protected void onError(Context arg0, String errorId) {
    Log.i(TAG, "Received error: " + errorId);
     displayMessage(arg0, getString(R.string.gcm_error, errorId));
}

@Override
protected boolean onRecoverableError(Context context, String errorId) {
     displayMessage(context, getString(R.string.gcm_recoverable_error,
                errorId));
    return super.onRecoverableError(context, errorId);

}
}
