原先想使用Push的方法實踐APP自動更新, 但在研究Google的C2DM之後, 發現想要以此方法實踐, 必須要有Android Market帳號, 註冊費US$25, 而且必須將APP放在公開的Android Market上, 這對企業內部開發的程序似乎不是很好的解決方案, 後來同事給我這篇文章Android应用程序的自动更新升级, 我就是試著以IIS實踐並修改部分程序, 流程大致如: 檢查網路>透過HTTP取得遠端的APP版本資訊>取得手機APP版本資訊>比較兩者>若不符就先下載新版APP至SDCard>再取代舊版>最後使用者必須手動開啟新版APP
原先想使用Push的方法實踐APP自動更新, 但在研究Google的C2DM之後, 發現想要以此方法實踐, 必須要有Android Market帳號, 註冊費US$25, 而且必須將APP放在公開的Android Market上, 這對企業內部開發的程序似乎不是很好的解決方案, 後來同事給我這篇文章Android应用程序的自动更新升级, 我就是試著以IIS實踐並撰寫MainMenu
流程大致如: 檢查網路>透過HTTP取得所有APP最新版本資訊>取得裝置APP版本資訊>比較兩者>
若不符就顯示下載或更新訊息, 再將新版APP儲存至SDCard, 安裝後自動開啟新APP, 結束MainMenu
若無不符就自動開啟所選的APP, 結束MainMenu
STP1. 編輯version.json下, VerName是給使用者看的版本, VerCode是開發者用的內部版本
STP2. 部屬version.json至IIS, 並設定MIME接受.json及.apk
STP3. Eclipse, Project>Proerties>JavaBuildPath>Libraries>AddExternalJAR..>json.jar>OK
STP4. 建立AndroidProject:MAinMenu, 設定APP/SDK版本及Permission如下,
\res\values\strings.xml, 新增String供MainActivity顯示版本資訊
