在BlackBerry上掃描可用的Wi-Fi網絡

Question

是否有任何RIM API可用，這將有助於獲取設備的可用網絡服務列表或只有Wi-Fi網絡，併爲任何網絡通信設置選定的網絡接入點？

我的應用程序是否可以禁用GPRS，WAP等移動網絡？

例如：
當應用程序啓動時，即使在設備上沒有設置以前的Wi-Fi網絡接入點並列出可用的Wi-Fi連接，它也應掃描Wi-Fi連接。然後用戶將選擇適當的Wi-Fi連接進行任何網絡通信連接。在應用程序之外，任何互聯網通信（如瀏覽器或任何其他應用程序）都應通過相同的選定Wi-Fi連接完成。 掃描Wi-Fi並設置連接與BlackBerry Wi-Fi設置幾乎相同。

我期待這樣做的BlackBerry OS 4.5,4.7和5.0。

更新

的事情是我在尋找通過應用程序的Wi-Fi掃描功能。就像通過應用程序，我可以掃描可用的Wi-Fi接入點或熱點，並通過選擇設備來設置其中一個接入點，然後連接到該設備進行通信。

基本上就是這樣，我們如何在BlackBerry的「管理連接」中設置Wi-Fi連接？我必須通過應用程序來做類似的事情。

從一些黑莓手機論壇，我才知道有包OS V5.0，即net.rim.device.api.wlan.hotspot包來獲得Wi-Fi熱點。但經過漫長的搜索，我沒有找到任何示例或對它的解釋。正如我試圖通過查看其API文檔來實現的，但我沒有成功。

如果你有任何關於這個或任何示例代碼的想法，這將是非常有益的。

那麼，要掃描應用程序的所有可用網絡，您可以使用RIM的NetworkDiagnostic tool。
