前言
原本在開發者沙盒(SandBox)模式下一切都還滿順利的,
不料上到Google Play發現原本的功能不work,
花了一些時間才發現小細節.
自己記錄一下, 同時也給需要的人參考一下.
以下我就自己的開發歷程,
先從沙盒模式說起,
最後再談關閉沙盒模式要注意的地方.
下載&Import FaceBook SDK
I'll skip the installation of Facebook in emulator here.
> Right click / 'File' on top
> Existing Android Code Into Workspace
> make sure the 'facebook' project is checked
如果Project有Error可以先檢查android-support-v4.jar的版本是否一致
最快的方法就是把最新的jar在project list裡面copy起來,
然後把其他project有用到的都先delete掉, 再paste上去.
環境設定
接下來看看我們的project要做哪些設定
1. library
2. Manifest設定
3. res/values/strings.xml加上
Facebook上建立應用程式後, copy App ID
4. 在Facebook App設定頁面加上Hash Key
Mac User
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
程式 - Facebook分享

正式版本
1. Facebook APP設定頁面一定要把SandBox mode關閉
2. 確認Android app package name
> Export Signed Application Package
> KeyStore path別忘記副檔名.keystore !
> 輸入key的資訊 (一個keystore可以有很多把keys), Alias就是key的名稱
3. 複製正式版本的hashed key (建議在keystore的目錄下)
keytool -exportcert -alias (key的名稱) -keystore (keystore名稱).keystore | openssl sha1 -binary | openssl base64
這樣submit的正式版app就能夠正常分享資訊到Facebook啦!
