"undefined reference to `typeinfo"

I use stl library in my Android project, so I add "stlport_static" in Application.mk.

However, this would cause the link error: "undefined reference to `typeinfo XXXXXX"

So, replace "stlport_static" with 

APP_STL := gnustl_static

Don't know reason, but works.

Handler, AsyncTask and Thread

Sometime confused about the differences between Handlers, AsyncTasks and Threads in Android.
If I have a time time consuming job that without relating with UI thread, should I use which one?

A stackoverflow thread show good answer:
http://stackoverflow.com/questions/6964011/handler-vs-asynctask-vs-thread

I know that:
1. All the things Handler and  AsyncTask can do, it can do with Thread.
2. Use AsyncTask when you are in UI thread.
3. Handler allows you to send and process Message and Runnable objects associated with a thread's MessageQueue <- and="" callback.="" form="" hide="" i="" it="" native="" preview="" show="" span="" surface="" to="" use="">
