鸟的天空用心记录生活的每一天……

VSPD顾名思义就是在本本上虚拟串口，实际上这个软件做的就是虚拟出一对已经互联的串口。

android实现状态栏添加图标的函数，具体如下：

private void showNotification() {   // 创建一个NotificationManager的引用   NotificationManager notificationManager = (NotificationManager)    AutoFile.this.getSystemService(android.content.Context.NOTIFICATION_SERVICE);   // 定义Notification的各种属性   Notification notification = new Notification(R.drawable.dvd,    "天籁之音播放器", System.currentTimeMillis());   notification.flags |= Notification.FLAG_ONGOING_EVENT; // 将此通知放到通知栏的"Ongoing"即"正在运行"组中   notification.flags |= Notification.FLAG_NO_CLEAR; // 表明在点击了通知栏中的"清除通知"后，此通知不清除，经常与FLAG_ONGOING_EVENT一起使用   notification.flags |= Notification.FLAG_SHOW_LIGHTS;   notification.defaults = Notification.DEFAULT_LIGHTS;   notification.ledARGB = Color.BLUE;   notification.ledOnMS = 5000;   // 设置通知的事件消息   CharSequence contentTitle = "天籁之音正在播放……"; // 通知栏标题   CharSequence contentText = "ameyume"; // 通知栏内容   Intent notificationIntent = new Intent(AutoFile.this, MyPlayerService.class); // 点击该通知后要跳转的Activity   PendingIntent contentItent = PendingIntent.getActivity(AutoFile.this, 0,    notificationIntent, 0);   notification.setLatestEventInfo(AutoFile.this, contentTitle, contentText,    contentItent);   // 把Notification传递给NotificationManager   notificationManager.notify(0, notification);  } 

Android：default activity not found

顾名思义，没有默认的activity

一般是AndroidManifest.xml里少了几句话，如图所示：
