CocosCreator 2.4.5 整合FB登入(Android App)

建立FB開發者應用程式

• https://developers.facebook.com/docs/facebook-login/android

加入FBLogin相依套件

• 在專案中開啟 your_app > Gradle Scripts > build.gradle（專案），確認 buildscript { repositories {}} 中列出了以下存放庫： jcenter()

• 在專案中開啟 your_app > Gradle Scripts > build.gradle（模組：應用程式），然後將下列實作陳述式新增至 dependencies{} 區塊以使用最新版的 Facebook 登入 SDK： implementation 'com.facebook.android:facebook-login:[8.1)'

• 建置您的專案。

• 
  

編輯資源和 Manifest

將應用程式與您的套件名稱和預設類別建立連結

提供您應用程式的「開發金鑰雜湊」和「發行金鑰雜湊

• keytool -exportcert -alias androiddebugkey -keystore ~/.android/xxx.keystore | openssl sha1 -binary | openssl base64

• Android 應用程式必須先以發行密鑰雜湊進行數位簽署，才能上傳至商店。若要產生發行密鑰雜湊，請在 Mac 或 Windows 上執行下列指令，並替換成您的發行密鑰別名和 KeyStore 路徑：

• keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64

實作FB登入的類(由於此類某些方法需要由cocos呼叫, 故呼叫的Fun一定要Static) 僅提供片段

初始化管理者

監聽主Activity的OnActivityResult()

Cocos呼叫原生

//FB登入
 fbLogin: function () {
 console.log("Facebook login");
 
 if (cc.sys.isNative) {
 if (cc.sys.os == cc.sys.OS_ANDROID) {
 let className = "tools/FacebookSdk";
 let methodName = "facebookLogin";
 let methodSignature = "()V";
 jsb.reflection.callStaticMethod(className, methodName,    methodSignature);
 }
