安卓脸书整合

Question

我正在开发一个想要集成 facebook 的 android 应用程序。我正在通过链接http://developers.facebook.com/docs/guides/mobile/#android

我有几个疑问：

1. 我使用 keytool 生成了密钥，但无法理解如何在移动和设备部分注册它。移动和设备部分在哪里？

2. 如何在我的应用程序中实现类似 facebook 的按钮功能？任何示例代码都会非常有帮助。

Answer 1

1) 走这条路：

• 转到http://www.facebook.com/developers/
• 点击右侧的应用链接
• 点击编辑设置（在右侧菜单上）
• 点击左侧菜单中的移动设备和设备。

2) 你想制作一个原生应用还是通过 webview 访问它？如果它是一个 webview，然后像在任何其他 html 代码中一样创建网页。要开始使用本机应用程序，您是否查看过以下示例：https://github.com/facebook/facebook-android-sdk/tree/master/examples/simple？

Answer 2

我并没有真正回答这个问题，但我建议在 Android 中使用共享意图，而不是需要身份验证的弹出 API。如果 Android 用户有 Facebook 帐户，他可能会拥有 facebook 应用程序。

更新： 查看文档：http://developer.android.com/reference/android/content/Intent.html

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"));

也许您只能直接针对 facebook 应用程序。

Answer 4

我已使用 facebook sdk 4.10.0 将登录功能集成到我的 android 应用程序中。我遵循的教程是：

Facebook login integration android studio.

您将能够从 facebbok 获取名字、姓氏、电子邮件、性别、facebook id 和出生日期。

以上教程还解释了如何通过视频在 facebook 开发者控制台中创建应用程序。
