如果你正在看這本書，你應該對深具挑戰的
Android
開發有些瞭解了。學習善用
Android
Developer Tools
（
ADT
）內的功能使開發更容易，且能提升程式碼品質，進而完成更
精緻及強大的產品。
為什麼需要開發者工具
Android
與其他目前的行動平台有很大的不同。
Android
並非由單一的組織所管理，而
是由數個致力於提供免費、完整、開放原始碼的行動裝置作業系統公司所組成的“開
放手持裝置聯盟（
Open Handset Alliance
）”來領導與開發。雖然這方法避免了公司對
平台的獨佔性，但也增加許多複雜性。包括：
多樣化的螢幕解析度
不同的
Android
裝置伴隨著多種不同的螢幕大小，你的
App
能否勝出取決於能否
支援在不同裝置的畫面解析度。
破碎化（
Fragmentation
）的平台
當有新的
Android
發佈時，是否升級到新的版本是由各個電信商及製造商來決定。
這通常不會立即發生，所以開發者必須要去支援舊的系統版本。
不同的硬體規格
Android
裝置不論在形狀、大小、效能上都有很大的不同。在受限制的硬體下，必
須減少那些不被支援的功能。另外一點很重要的是，你不能依賴一些特定的硬體
設備（例如：沒有相機、
GPS
或是鍵盤的裝置上）。
