La notification du constructeur est obsolète

Question

Je suis très nouveau sur Android développement d'applications. Avec l'aide de tant de tutoriels, j'ai créé une application avec webview, actionbar et GCM. Tout fonctionne bien. Mais je reçois un avertissement "Le constructeur notification is deprecated ". J'ai suivi notification.builder. mais je ne suis pas en mesure de modifier mes codes avec le nouveau générateur de notifications. Quelqu'un peut-il m'aider .....

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);      

}

Answer 1

Vous essayez d'utiliser le constructeur de Notification qui est obsolète à partir de l'API 11. Cela signifie qu'il n'est plus pris en charge et ne doit pas être utilisé. utilisez plutôt Notification.Builder 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();

Vous disposez actuellement des éléments suivants:

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

Ce constructeur est déconseillé au profit de Notification.Builder qui ressemblerait à ceci:

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

Quant à la question d'origine, cette classe fonctionne correctement, si votre système prend en charge 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);      

 }
