無法通過android 3.2上的javamail API發送電子郵件

Question

編輯：解決方案Hiren給工作。非常感謝！對於那些有類似問題的人，請按照以下說明進行操作：Android Honeycomb: NetworkOnMainThreadException even when using AsyncTask and no strict mode?

再次感謝！

我正在爲galaxy選項卡開發應用程序，但無法從選項卡發送電子郵件。我找到的代碼可以在其他地方（包括我的手機）使用，但它的確可以使用not work on the tab。

我得到的，當我試圖通過JavaMail來發送郵件的例外情況是這樣的：

不加載file: /system/lib/javamail.providers

我試圖使用該解決方案如下建議和我有以下異常：
