第十二週 利用app模擬器製作app

先到http://appinventor.mit.edu/explore/content/windows.html 點選dowmload下載模擬器

然後選擇 3. Start App Inventor 進入畫面

登入google帳號 & 進入此連結  http://beta.appinventor.mit.edu/.

打開模擬器並照以上網址的步驟設計

若要測試模擬器結果 可點選New emulator 再點選 Connect to Device連線5554

若要存成apk檔，回到網頁 點選Package for Phone，再選擇Download to this Computer

可將檔案傳到facebook 再利用手機連線FB 下載，即可使用app

註:限android手機
