I was doing the HelloTabWidget tutorial http://developer.android.com/resources/tutorials/views/hello-tabwidget.html and getting errors on the "TabHost tabHost = getTabHost();" statement. I thumbed threw the stackOverflow notes and it seems a few people were having the same problem, and a few received responses along the lines of "Note: Tabactivitity deprecated in latest versions, consider learning Fragments" and discovered I can use ... the v4 support library which provides a version of the Fragment API that is compatible down to DONUT. although I haven t quiet figured out how to do this.
我的问题是:如果该功能被贬低,并造成新生问题,那么教程是否应该更新以使用新功能?它们是否是一种礼貌/政治上正确的方法,让负责教程的人知道更新可能符合程序?或者说也许存在新的教程,而我只是在看一个旧的 URL?
