#AndroidTutorial
2+
3+
你對「Tutorial」有什麼樣的感覺？每一種技術的Tutorial都告訴你這是學習的開始，不過最後好像都會變成折磨的開始。或許可以找出一種方式，讓Tutorial變成大家會很想要點它的超連結！
4+
5+
要認識一種開發技術，每個人選擇的方式都會不太一樣，如果再加上只能使用非常簡短的時間，你會選擇哪一種方式呢？我的決定是選一個Android APP！
6+
7+
這個Android APP會在短短六小時的課程內容，帶領你認識大部份Android APP開發時會遇到的主題，從APP的規劃開始，畫面、互動、資料庫、多媒體、檔案、服務、通知、位置、地圖還有小工具，這些就是你會學到的東西。
