通过Android系统日志监听程序启动事件

经常有这样的需求：在程序A启动之后，在这个程序上覆盖一个界面，让用户输入密码后才能启动程序A，这类场景主要集中在安全软件中。

那应该怎样得知某某程序启动了，系统没有相应的广播，这很难知道程序启动了。

既然没有通知，那我们就只能用最笨的方法：主动去询问最近启动过哪些程序。

这需要用后台服务器一直跑，每隔一段时间就询问一次。程序启动的时候，会在Logcat中打印出一些日志信息，其中就有类似下面的日志，表明是启动了哪个程序

01-21 15:09:56.957: I/ActivityManager(240): START {act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.estrongs.android.pop/.view.FileExplorerActivity u=0} from pid 2176

这些日志都可以通过以下代码读取到，并且提供了解析包名的相应方法：

     try {int tagCode = EventLog.getTagCode("am_proc_start");Collection<Event> output = new ArrayList<EventLog.Event>();EventLog.readEvents(new int[] { tagCode }, output);for (Event event : output) {// PID, UID, Process Name, Type, ComponentObject[] objects = (Object[]) event.getData();ComponentName componentName = ComponentName.unflattenFromString(objects[4].toString());String packageName = componentName.getPackageName();Log.d(TAG, "packageName=" + packageName);}} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}

那么你可能要问，“am_proc_start”这个Tag名是哪来的，那我们就把android.util.EventLog的代码翻出来看一下：

}

发现EventLog的Tag名称来自一个文件/system/etc/event-log-tags，文件内容列出来，就可以看到已经定义好的各种Tag，这样子，想监听哪些事件，都可以一目了然了。
