Android™ How to Program, Second Edition

4.1. Introduction

Twitter’s search mechanism makes it easy to follow trending topics being discussed by more than 500 million Twitter users. Searches can be fine tuned using Twitter’s search operators (overviewed in Section 4.2), often resulting in lengthy search strings that are time consuming and cumbersome to enter on a mobile device. The Twitter Searches app (Fig. 4.1) allows you to save your favorite search queries with short tag names that are easy to remember (Fig. 4.1(a)). You can then touch a tag name to quickly and easily follow tweets on a given topic (Fig. 4.1(b)). As you’ll see, the app also allows you to share, edit and delete saved searches.
