Android event logcat的研究
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.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>();
EventLog.readEvents(new int[] { tagCode }, output);
for (event : output) {
// PID, UID, Process Name, Type, Component
Object[] 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 block
e.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/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。
