LinkedIn Android force close error

Question

我正在將LinkedIn應用程序與我的Android應用程序集成。我在運行應用程序時遇到了強制關閉錯誤。我是否需要在我的android應用程序中添加任何外部庫來支持LinkedIn應用程序？

任何有效的示例代碼示例都會對我有很大的幫助。

Answer 1

您需要學習如何在Eclipse中進行調試以及如何使用ADB和DDMS工具。

爲了獲得關於異常/強制關閉的更多細節，您需要在Eclipse中尋找一個名爲Logcat的視圖（您可以在DDMS的透視圖中找到），您將找到詳細的追溯時間/內容和行數是問題。

爲此，您應該閱讀完整文章約Debugging in Android using Eclipse
