嗨，我想知道什麼是我必須遵循的過程，以便自我發佈我的網站上的應用程序。只是將.apk文件放在網站中，並提供一個指向用戶的鏈接（從手機）到應用程序並安裝它？如何自我發佈android應用程序
- 用戶是否需要一些額外的知識才能安裝該應用程序？
- 用戶可以一鍵安裝嗎？
- 如何更新，用戶可以在有新版本時收到通知？
- 升級到新版本時用戶是否需要卸載並重新安裝應用程序？
在此先感謝。

- 沒有額外的知識，他們只需點擊一下即可安裝。但是，他們必須安裝在設置中啓用的「非市場應用程序」。
- 更新通知只能在您的應用程序中編程時才能使用。請求您網站上的某種標誌或其他內容。所以沒有基本的支持
- 你不需要卸載並重新安裝。請注意你的versionNumber。

- 用戶是否需要一些額外的知識才能安裝該應用程序？ 是的。未經授權在應用程序設置處安裝「未知來源」，您無法安裝未簽名的應用程序。
- 用戶可以一鍵安裝嗎？ 沒有。他必須讓你的網站，下載它，打開它並批准他想安裝它。
- 有關更新，用戶可以在有新版本時收到通知嗎？ 我認爲更新支持僅適用於市場應用。您需要自己寫點東西
- 用戶在升級到新版本時是否需要卸載並重新安裝應用程序？ 查看上面的答案 - 取決於你如何實現它。

如果我註冊什麼像這樣的應用程序：http://mobile.tutsplus.com/tutorials/android/publish-to-android-market/將在用戶仍然需要有「非市場應用程序」在設置中啓用？ – madcoderz 2011-01-11 10:14:19
是的。對於所有不從市場安裝的apks，您需要啓用該複選框，據我所知。這就是它的意圖，所以如果你找到了解決方法（我懷疑），你可以稍後等待它「固定」。 – Nanne 2011-01-11 10:23:52
