Creating News Aggregator

Hi , i am new in yii framework , for now i am working with the project of news aggregator i was asking if is it vital to create engine that will automatically collect all news feeds at once and add an android app on top of that… if that is true then would you advice which step do i take or any resource material that i may follow to accomplish my task?

Thanks
