PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
Notification notification = new NotificationCompat.Builder(this,"default")
.setContentTitle("This is content title")
.setContentText("This is content text")
.setWhen(System.currentTimeMillis())
// .setSmallIcon(R.mipmap.ic_launcher)
//.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
.setContentIntent(pendingIntent)
.build();
startForeground(startId, notification);
点击之后，抛出异常
