2 Outline 一、App Inventor簡介 二、建立App Inventor下的android開發環境

3 一、App Inventor簡介 App Inventor簡介 目的：讓非專業程式設計師也能開發出好用的應用程式

4 App Inventor簡介(2) Android：以Linux為基礎的作業系統，主要使用在智慧型行動裝置上，如：智慧型手機、平板電腦等。 Android App：Android應用程式(Android Applications)，可在Android作業系統上執行的應用程式。 App Inventor：用來開發Android App的圖形化編輯器，設計中的程式需透過瀏覽器來呈現。由App Inventor伺服器儲存相關的專案。 2010/12/15 Google釋出 2011/12/31 移回MIT繼續開發

5 App Inventor簡介(3) App Inventor建立應用程式需要二大模組： 手機或模擬器上呈現結果
The App Inventor Designer The App Inventor Blocks Editor 手機或模擬器上呈現結果 「The App Inventor Designer, where you select the components for your app. The App Inventor Blocks Editor, where you assemble program blocks that specify how the components should behave. You assemble programs visually, fitting pieces together like pieces of a puzzle.」

6 二、建立App Inventor下的android開發環境
１．使用者必須擁有Gmail帳號 ２．使用者電腦必須安裝Java JDK 6以上 ３．安裝App Inventor

7 申請Gmail帳號(1) Gmail帳號，是每一個App Inventor程式開發者必備的帳號， 藉由Gmail帳號來登入App Inventor官坊網站網。 ==>右上角「登入」

8 申請Gmail帳號(2) 有Google帳號：直接登入 無Google帳號：利用「免費建立帳戶」，進行Gmail帳號的建立

9 申請Gmail帳號(3) 進入「免費建立帳戶」的頁面，依序輸入所需資料
輸入所需資料說明如下： 「 １‧名稱：姓氏、名字 ３‧建立密碼、確認密碼 ４‧生日：YYYY年MM月DD日 ５‧性別：男生、女生 ６‧行動電話 ７‧您目前的電子郵件地址 ８‧協助我們排除自動程式：防止機器人的亂數影像（請輸入這兩個字） ９‧地區：台灣、日本... １０‧Google條款： １０－１‧我同意 Google《服務條款》及《隱私權政策》 １０－２‧Google 可使用我的帳戶資訊，在 Google 以外的網站為我提供個人化的推薦內容和廣告。關於個人化服務。 」

10 申請Gmail帳號(4) 首次使用Gmail時，Google會要求輸入相關資訊，依序輸入 ：國家地區、行動電話號碼、備援電子郵件地址，來作為密碼忘記的處理機制。 輸入完畢後，點選「儲存並繼續」。

11 申請Gmail帳號(5) 第一次進入Gmail的操作頁面時，會有歡迎畫面出現
進入到Gmail的頁面，Google預設會寄三封信件到您的信箱中。

12 安裝Java JDK(1) 執行App Inventor 需要安裝Java JDK 6以上。可至Java官方網站所提供的網頁進行測試 或者到Java官方網址： ，選擇「我有 Java 嗎？」進行檢測

13 安裝Java JDK(2) 點選「驗證Java版本」，進行Java JDK的檢測
驗證完成後，網頁畫面會依照該使用者的安裝狀況出現相對應的訊息，並建議安裝最新的版本

14 安裝Java JDK(3) 若選擇「立刻下載 Java 」「同意並開始免費下載」  「執行」，以安裝最新版本
在頁面的下方有兩個聯結點，分別為「安裝說明」、「系統需求」。 在「系統需求」下我可以查看，安裝Java JDK基本需求的說明。 該說明如下： 「 Windows 系統需求： Windows 7、Vista、Windows XP、Windows Server 2008 支援 Intel 及百分之百相容的處理器。建議使用 Pentium 166MHz 或更快的處理器，至少具備 64MB 的實體 RAM。最少還需要 98MB 的可用磁碟空間。 」 一般使用者授權合約如下： Oracle Binary Code License Agreement for the Java SE Platform Products and JavaFX ORACLE AMERICA, INC.

20 安裝App Inventor(5) 執行「 Next 」後，網頁畫面如下方左圖所示
讀者可以按下「Install」進行安裝，最後按下「Finish」完成安裝

21 三、利用App Inventor開發App

22 進入App Inventor官方網站http://www. appinventor. mit
進入App Inventor官方網站 Inventor的開發

23 登入Google後，網頁畫面如下圖所示。
此畫面表示為讀者是否同意「麻省理工學院」向Google存取您的Google帳號，但不包含您的密碼及其他個人資訊 讀者確認自己帳號後，即可點選「Allow」後，並繼續進行App Inventor的開發，若登入畫面不是您的帳號時。可以點選 「Sign in to another account」的聯結點，切換其他帳號登入 「麻省理工學院」向「Google」存取您的Google帳號的詳細說明如下： 「 Google is not affiliated with the contents of MIT AppInventor Experimental or its owners. If you sign in, Google will share your address with MIT AppInventor Experimental but not your password or any other personal information. 」

24 第一個App(1) 登入完成後，即可進入 App Inventor的開發網頁
在App Inventor的開發網頁的功能列，點選「New」功能選單後，在「Project name：」的欄位裡面，輸入專案名稱，按下「ＯＫ」即可新增一個新的專案 此範例專案名稱為：HelloApp。本專案初始畫面為一個按鈕，按下按鈕後秀出文字。

25 第一個App(2) 在新增一個新的專案名稱後，即可看到專案名稱為「 HelloApp 」的設計畫面。
在畫面中主要分成四個區域，由左至右分別為：Palette（元件工具箱）、Viewer（開發設計區）、Components（現在使用的物件）、Properties（物件屬性），四大區域。

26 第一個App(3) 分別將Palette（元件工具箱）內的Button（按鈕）和Label（標籤）兩個元件，拖曳至Viewer（開發設計區）後，即可在執行畫面內加入物件。

27 第一個App(4) 在Components （現在使用的物件）區域內選擇Screen1後，並且在Properties （屬性）區域內更改 Title，成為合適的程式名稱：在此改為HelloApp

28 第一個App(5) 在Components（現在使用的物件）區域內選擇Button1（按鈕物件）後，並且在Properties（屬性）區域內分別更改： FontSize （文字大小）、Text（物件的字串）、Width（物件寬度） 此範例設定為： FontSize （文字大小）：４０ Text（物件的字串）：按鈕測試 Width（物件寬度）： Fill Parent

29 第一個App(6) 在Components（現在使用的物件）區域內選擇Label1（按鈕物件）後，並且在Properties（屬性）區域內分別更改： FontSize （文字大小）、Text（物件的字串）、Width（物件寬度）。 此範例設定為： FontSize （文字大小）：４０ Text（物件的字串）：” ”（空字串） Width（物件寬度）： Fill Parent

30 第一個App(7) 個別設定好Screen1（螢幕物件）、 Button1（按鈕物件）、Label1（按鈕物件）的Properties（屬性）後「Open the Blocks Editor」，開啟拼塊編輯器，以編輯視覺化程式

31 第一個App(8) 選擇「Open the Blocks Editor」功能時，會要求安裝AppInventorForAndroidCodeblocks.jnlp ，安裝驗證完才能正確執行「拼塊編輯器」

32 第一個App(9) 開啟「App Inventor For Android Blocks Editor」後的執行畫面如下圖所示。
在左邊的功能列中分為三大類：Built-in（內建） 、My Blocks（自我設計的拼塊） 、Advanced（進階）。

33 第一個App(10) 選擇「My Blocks」，即可在下方的物件列表中，看到剛剛我們所加入的物件， Screen1、 Button1、Label1。 選擇「Button1」物件後，系統即會秀出「Button1」物件所對應的指令或觸發事件（皆有對應的拼塊）。事件列表中選擇「when Button1.Click」事件，這表示當「Button1」物件被按下時會觸發所對應的方法或副程式。 選擇此觸發事件後，在畫面上即會加入「when Button1.Click」事件拼塊。

34 第一個App(11) 選擇「Label1」物件後，系統即會秀出「Label1」物件所對應的指令或觸發事件。事件列表中選擇「set Label1.Text to」指令，這表示代表設定「Label1」的文字(Text)中內容的參數指令。 選擇指令後，在畫面上即會加入「set Label1.Text to 」指令拼塊。

35 第一個App(12) 當觸發「when Button1.Click」事件時，要執行「set Label1.Text to」的指令，就是「set Label1.Text to」指令拼圖拖曳至「when Button1.Click」事件拼圖內即可。

36 第一個App(13) 在左邊的功能列中選擇「Built-in」，即可在下方的元件列表中，看到許多可使用的對應參數元件，選擇「Text」元件後，系統即會秀出「Text」元件所對應的指令。指令列表中選擇「Text」參數，這表示代表設定「Text 」元件文字的參數。 選擇指令後，在畫面上即會加入「Text」物件拼圖。

37 第一個App(14) 讀者可以自行將「Text」元件拼圖上的參數「Text」更改成自己所需要的字串。
範例所更改的字串參數為： 「This is my first App !」。

38 第一個App(15) 當觸發「when Button1.Click」事件時，要執行「set Label1.Text to」的指令，並將「Lable1」元件的「Text」的參數內容更改為自訂的參數，就是將「Text」元件拼塊拖曳至「set Label1.Text to」指令拼圖內即可。

39 第一個App(16) 點選「App Inventor For Android Blocks Editor」右上方的「New Emulator」功能來啟動模擬器。 若已經有實體裝置，則可以省略啟動模擬器這一步驟。 下圖為有關模擬器的詳細說明。 有關模擬器的詳細說明如下： 「 Please wait. It can take 2 or 3 minutes for the emulator to become ready — even longer the first time. The emulator will be ready when the phone screen has a picture background as shown in the right image here. If it has a lock screen, as shown in the left, slide the bar with the green lock icon to the right to unlock it. Even after the picture appears, continue to wait for the emulator to finish preparing the SD card: watch the notification area at the top of the emulator screen. When the emulator is ready, choose it from the Connect to Device menu to connect The Troubleshooting Guide at may provide further help. 」

40 第一個App(17) 點選「App Inventor For Android Blocks Editor」右上方的「New Emulator」的功能後，即可擁有Android模擬器。啟動後的模擬器要記得解除鎖定。

41 第一個App(18) 點選「App Inventor For Android Blocks Editor」右上方的「Connect to Device...」 , 來選擇預連結的模擬器，或是使用者的實體裝置。 此範例所選擇的裝置為：「Emulator 5554」的模擬器。 當程式正在連結時，右邊的手機圖示會變成閃爍的黃色圖示。 當程式連結完成時，右邊的手機圖示會變成綠色圖示。

42 第一個App(19) 選擇好連結App Inventor的裝置後，即可在裝置上看到我們所設計的程式執行畫面。
點選「測試按鈕」的物件後，Label1上的字串即更改為「This is my first App!」。 做到此步驟時，已完成利用App Inventor撰寫android程式
