我有一个小问题，但不明白如何解决这个问题。

我创建了一个用于提供通知的类，但这些行被标记为已弃用：

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

替代方法是：

...
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
...

我可以写一个类似的代码：

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
    ...
}

我提供的最低 sdk 版本为“8”。

我确实喜欢下面：

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
        }

我可以为else部分写什么？

这就是我最终得到解决方案的方式：

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);
        }

上述解决方案有效。尽管如此，由于NotificationCompat.Builder引入了类，我们可以跳过 if 条件来检查是否比较当前 API 版本。所以，我们可以简单地删除if...else条件，然后继续：

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);

这是获得水平的正确方法。

 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
}
