I am very new to android app development. With the help of so many tutorials, i created an app with webview, actionbar and GCM. Everything works fine. But i am getting a warning "The constructor notification is deprecated". I have gone through notification.builder. but i am not able to modify my codes with new notification buider. Can someone help me.....

public class GCMIntentService extends GCMBaseIntentService {

private static final String TAG = "GCMIntentService";

public GCMIntentService() {
    super(SENDER_ID);
}

/**

    Log.i(TAG, "Device registered: regId = " + registrationId);
    displayMessage(context, "Your device registred with GCM");
    Log.d("NAME"," "+ MainActivity.name);
    ServerUtilities.register(context, MainActivity.name, MainActivity.email, MainActivity.AndroidVersion, MainActivity.AndroidID, MainActivity.manufacturer, MainActivity.model, registrationId);
}

/**

    Log.i(TAG, "Device unregistered");
    displayMessage(context, getString(R.string.gcm_unregistered));
    ServerUtilities.unregister(context, registrationId);
}

/**

    Log.i(TAG, "Received message");
    String message = intent.getExtras().getString("price");

    displayMessage(context, message);
    // notifies user
    generateNotification(context, message);
}

    Log.i(TAG, "Received recoverable error: " + errorId);
    displayMessage(context, getString(R.string.gcm_recoverable_error,
            errorId));
    return super.onRecoverableError(context, errorId);
}

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

    String title = context.getString(R.string.app_name);

    Intent notificationIntent = new Intent(context, MainActivity.class);
    // 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, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    // Play default notification sound
    notification.defaults |= Notification.DEFAULT_SOUND;

    //notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");

    // Vibrate if vibrate is enabled
    notification.defaults |= Notification.DEFAULT_VIBRATE;
    notificationManager.notify(0, notification);      

}

推荐答案

您正在尝试使用的构造是德precated为API 11这意味着它的通知是不支持任何更长，不应该使用。使用Notification.Builder代替<一个href="https://developer.android.com/reference/android/app/Notification.Builder.html">https://developer.android.com/reference/android/app/Notification.Builder.html

You're attempting to use the constructor for Notification which is deprecated as of API 11. Meaning it isn't supported any longer and should not be used. use Notification.Builder instead https://developer.android.com/reference/android/app/Notification.Builder.html

 Notification noti = new Notification.Builder(mContext)
     .setContentTitle("New mail from " + sender.toString())
     .setContentText(subject)
     .setSmallIcon(R.drawable.new_mail)
     .setLargeIcon(aBitmap)
     .build();

您目前有以下几种：

Notification notification = new Notification(icon, message, when);

此构造方法是去precated赞成Notification.Builder的他们看起来就会像下面这样：

This constructor is deprecated in favor of the Notification.Builder which would look like the following :

Notification notification = new Notification.Builder(context)
    .setContentText(message)
    .setSmallIcon(icon)
    .setWhen(when)
    .build();
