The constructor notification is deprecated

Question

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); }  /**  * Method called on device registered  **/ @Override protected void onRegistered(Context context, String registrationId) {     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); }  /**  * Method called on device un registred  * */ @Override protected void onUnregistered(Context context, String registrationId) {     Log.i(TAG, "Device unregistered");     displayMessage(context, getString(R.string.gcm_unregistered));     ServerUtilities.unregister(context, registrationId); }  /**  * Method called on Receiving a new message  * */ @Override protected void onMessage(Context context, Intent intent) {     Log.i(TAG, "Received message");     String message = intent.getExtras().getString("price");      displayMessage(context, message);     // notifies user     generateNotification(context, message); }  /**  * Method called on receiving a deleted message  * */ @Override protected void onDeletedMessages(Context context, int total) {     Log.i(TAG, "Received deleted messages notification");     String message = getString(R.string.gcm_deleted, total);     displayMessage(context, message);     // notifies user     generateNotification(context, message); }  /**  * Method called on Error  * */ @Override public void onError(Context context, String errorId) {     Log.i(TAG, "Received error: " + errorId);     displayMessage(context, getString(R.string.gcm_error, errorId)); }  @Override protected boolean onRecoverableError(Context context, String errorId) {     // log message     Log.i(TAG, "Received recoverable error: " + errorId);     displayMessage(context, getString(R.string.gcm_recoverable_error,             errorId));     return super.onRecoverableError(context, errorId); }  /**  * Issues a notification to inform the user that server has sent a message.  */ private static void generateNotification(Context context, String message) {     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);      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);        }  }

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)      .setContentIntent(yourPendingIntent)      .build(); 

You currently have the following :

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

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();

As for the original question, this class works fine, if your system supports GCMBaseIntentService:

package ...;  import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.util.Log;  import com.google.android.gcm.GCMBaseIntentService;  import static com.example.taxiprofessional.CommonUtilities.SENDER_ID; import static com.example.taxiprofessional.CommonUtilities.displayMessage;  public class GCMIntentService extends GCMBaseIntentService {      private static final String TAG = "GCMIntentService";   public GCMIntentService() {      super(SENDER_ID);  }   /**   * Method called on device registered   **/  @Override  protected void onRegistered(Context context, String registrationId) {      Log.i(TAG, "Device registered: regId = " + registrationId);      displayMessage(context, "Your device registred with GCM");      AccountInformation info=AccountInformation.sharedInstance();      ServerUtilities.register(context, info.email, info.password, registrationId);  }   /**   * Method called on device un registred   * */  @Override  protected void onUnregistered(Context context, String registrationId) {      Log.i(TAG, "Device unregistered");      displayMessage(context, getString(R.string.gcm_unregistered));      ServerUtilities.unregister(context, registrationId);  }   /**   * Method called on Receiving a new message   * */  @Override  protected void onMessage(Context context, Intent intent) {      Log.i(TAG, "Received message");      String message = intent.getExtras().getString("price");       displayMessage(context, message);      // notifies user      generateNotification(context, message);  }   /**   * Method called on receiving a deleted message   * */  @Override  protected void onDeletedMessages(Context context, int total) {      Log.i(TAG, "Received deleted messages notification");      String message = getString(R.string.gcm_deleted, total);      displayMessage(context, message);      // notifies user      generateNotification(context, message);  }   /**   * Method called on Error   * */  @Override  public void onError(Context context, String errorId) {      Log.i(TAG, "Received error: " + errorId);      displayMessage(context, getString(R.string.gcm_error, errorId));  }   @Override  protected boolean onRecoverableError(Context context, String errorId) {      // log message      Log.i(TAG, "Received recoverable error: " + errorId);      displayMessage(context, getString(R.string.gcm_recoverable_error,              errorId));      return super.onRecoverableError(context, errorId);  }   /**   * Issues a notification to inform the user that server has sent a message.   */  private static void generateNotification(Context context, String message) {      int icon = R.drawable.taxi_profi;      long when = System.currentTimeMillis();      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, Dashboard.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;       // Vibrate if vibrate is enabled      notification.defaults |= Notification.DEFAULT_VIBRATE;      notificationManager.notify(0, notification);         }  }
