Implementieren der veralteten Benachrichtigungsmethoden

Ich habe ein kleines Problem, verstehe aber nicht, wie ich da rauskomme.

Ich habe eine Klasse zum Bereitstellen von Benachrichtigungen erstellt, aber diese Zeilen sind als veraltet markiert:

...
Notification notification = new Notification(icon, text, time); // deprecated in API level 11
...
notification.setLatestEventInfo(this, title, text, contentIntent); // deprecated in API level 11
...

Alternative Methoden sind:

...
Notification noti = new Notification.Builder(mContext)
         .setContentTitle("New mail from " + sender.toString())
         .setContentText(subject)
         .setSmallIcon(R.drawable.new_mail)
         .setLargeIcon(aBitmap)
         .build(); // available from API level 11 and onwards
...

Kann ich einen Code schreiben wie:

if(API_level < 11)
{
...
    Notification notification = new Notification(icon, text, time); // deprecated in API level 11
    ...
    notification.setLatestEventInfo(this, title, text, contentIntent); // deprecated in API level 11
    ...
}

else
{
    ...
    Notification noti = new Notification.Builder(mContext)
             .setContentTitle("New mail from " + sender.toString())
             .setContentText(subject)
             .setSmallIcon(R.drawable.new_mail)
             .setLargeIcon(aBitmap)
             .build(); // available from API level 11 and onwards
    ...
}

Ich biete die minimale SDK-Version als "8".

Bearbeiten:

Ich mochte unten:

int currentapiVersion = Android.os.Build.VERSION.SDK_INT;
        if (currentapiVersion < Android.os.Build.VERSION_CODES.HONEYCOMB){

            Notification notification = new Notification(icon, text, time);

            PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, TaskDetails.class), 0);

            notification.setLatestEventInfo(this, title, text, contentIntent);

            notification.flags |= Notification.FLAG_AUTO_CANCEL;

            mNM.notify(NOTIFICATION, notification);
        } 
        else
        {
            // what to write here
        }

Was kann ich für else Teile schreiben?

So kam ich zur Lösung:

if (currentapiVersion < Android.os.Build.VERSION_CODES.HONEYCOMB) {

            notification = new Notification(icon, text, time);
            notification.setLatestEventInfo(this, title, text, contentIntent); // This method is removed from the Android 6.0
            notification.flags |= Notification.FLAG_AUTO_CANCEL;
            mNM.notify(NOTIFICATION, notification);
        } else {
            NotificationCompat.Builder builder = new NotificationCompat.Builder(
                    this);
            notification = builder.setContentIntent(contentIntent)
                    .setSmallIcon(icon).setTicker(text).setWhen(time)
                    .setAutoCancel(true).setContentTitle(title)
                    .setContentText(text).build();

            mNM.notify(NOTIFICATION, notification);
        }

Bearbeiten:

Die obige Lösung funktioniert. Trotzdem, seit NotificationCompat.Builder Klasse eingeführt wurde, können wir die if-Bedingung zum Prüfen überspringen, die die aktuelle API-Version vergleicht. Also können wir einfach den if...else Bedingung, und gehen Sie mit:

NotificationCompat.Builder builder = new NotificationCompat.Builder(
                        this);
notification = builder.setContentIntent(contentIntent)
                      .setSmallIcon(icon).setTicker(text).setWhen(time)
                      .setAutoCancel(true).setContentTitle(title)
                      .setContentText(text).build();
mNM.notify(NOTIFICATION, notification);

Dies ist der richtige Weg, um das Level zu erreichen.

 final int sdkVersion = Integer.parseInt(Build.VERSION.SDK);

if (sdkVersion < Build.VERSION_CODES.HONEYCOMB)
{
...
Notification notification = new Notification(icon, text, time); // deprecated in API level 11
...
notification.setLatestEventInfo(this, title, text, contentIntent); // deprecated in API level 11
...
}
else
{
Notification noti = new Notification.Builder(mContext)
         .setContentTitle("New mail from " + sender.toString())
         .setContentText(subject)
         .setSmallIcon(R.drawable.new_mail)
         .setLargeIcon(aBitmap)
         .build(); // available from API level 11 and onwards
}
