安卓Facebook集成

Question

我正在开发一款安卓应用程序，需要集成Facebook的“点赞”功能。我正在阅读这个链接：http://developers.facebook.com/docs/guides/mobile/#android。我有几个问题：

1. 我使用keytool生成了密钥，但不知道如何在Mobile and Devices部分注册它。Mobile and Devices部分在哪里？
2. 我该如何在我的应用程序中实现Facebook的“点赞”按钮功能？提供任何示例代码都将非常有帮助。

祝好， Sapan

Answer 1

1) 按照以下步骤进行:

• 前往http://www.facebook.com/developers/
• 点击右侧的应用链接
• 在右侧菜单中点击编辑设置
• 在左侧菜单中点击移动设备。

2) 你想要创建一个原生应用程序还是通过 webview 访问？如果是 webview，则像任何其他 html 代码一样创建网页。如果要开始使用原生应用程序，是否看过以下示例：https://github.com/facebook/facebook-android-sdk/tree/master/examples/simple?

我正在寻找制作一个本地应用程序，用户可以在其中喜欢某个项目并在Facebook上分享..你有任何示例代码吗？ - Sapan

Answer 2

我并没有真正回答这个问题，但我建议在安卓中使用共享意图而不是需要验证的弹出API。如果一个安卓用户有Facebook账号，他很可能已经安装了Facebook应用程序。

更新： 请查看文档：http://developer.android.com/reference/android/content/Intent.html 大致应该是这样的：

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Extra message");

startActivity(Intent.createChooser(intent, "message"));

也许你可以直接针对 Facebook 应用程序进行操作。

我并不是很理解这个。你能否请解释一下？ - Sapan

通过意图与 Facebook 分享目前存在漏洞，希望能尽快修复。https://dev59.com/R3A75IYBdhLWcg3wBkO1 - Kyle Clegg

使用意图进行共享是一种好的实践，但在分享文本和图片时，例如在Facebook上，这种方法不起作用。Facebook希望您使用其API。 - j.c

Answer 3

我使用了Facebook SDK 4.10.0来集成Android应用程序中的登录功能。我遵循的教程是： Facebook login integration android studio. 您将能够从Facebook获取名字，姓氏，电子邮件，性别，Facebook ID和出生日期。

上述教程还通过视频解释了如何在Facebook开发者控制台中创建应用程序。
