如何在Android Studio 1.0.1上運行Facebook示例應用程序

Question

我一直在嘗試運行Facebook SDK示例應用程序（Scrumptious，FriendPickerSample等），但無濟於事。 我在Facebook SDK文件夾中有一個名為“samples”的文件夾，我作為項目導入。 然后，我就可以在Android Studio窗口中運行任何示例應用程序。 但是每當我運行其中一個應用程序時，我會得到100個錯誤和12個警告：

這對我來說似乎很奇怪，因為所有這些錯誤都來自facebook sdk，例如Session.java。 這是我的項目視圖的屏幕截圖：

提前致謝。

Answer 1

好的，我很安靜，但我覺得你的Project沒有support-v4庫。 它是Facebook用於項目中的片段和廣播管理器的庫。 您可以使用沒有片段的Facebook登錄按鈕，但建議將其與片段一起使用

只需在Gradle構建依賴項中添加以下行

編譯'com.android.support:support-v4:22.0.+'

我認為它應該工作
