我有以下代码，其给我的“build()未在Notification.Builder中定义”错误。

Notification.Builder notificationBuilder = new Notification.Builder(mApplicationContext)
                            .setContentIntent(pendingIntent)
                            .setContent(mContentView)
                            .setSmallIcon(android.R.drawable.stat_sys_warning)
                            .setAutoCancel(true);                   

// Send the notification
NotificationManager mNotificationManager = (NotificationManager) mParentActivity.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(MY_NOTIFICATION_ID, notificationBuilder.build());

最佳答案

由于您的目标是API 19和最小API 13(HC)，因此需要使用NotificationCompat.Builder-尝试:

  NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
                    mApplicationContext);
  Notification notification = notificationBuilder.setContentIntent(pendingIntent)
                    .setContent(mContentView)
                    .setSmallIcon(android.R.drawable.stat_sys_warning)
                    .setAutoCancel(true).build();
// Send the notification
NotificationManager mNotificationManager = (NotificationManager) mParentActivity.getSystemService(Context.NOTIFICATION_SERVICE);

            mNotificationManager.notify(0, notification);
