Android上的ksoap和minSdkVersion =「11」

Question

我在使用kso​​ap通過android調用webservice時遇到問題。如果minSdkVersion =「11」，那麼我得到一個異常，你可以在下面看到。但如果我將minSdkVersion屬性的值設置爲9或以下，則可以調用web服務。 ksoap和minsdkversion有什麼問題？請幫助我，我該怎麼辦？

ps：現在我要開發一個應用程序，它將在平板電腦（蜂窩）上運行。而我的目標API級別已經設置好的爲11

編輯：我使用kso​​ap2-機器人組裝-2.4-JAR-與依賴性

Answer 1

要調用網絡操作（主用戶界面線程上的webservice通過ksoap）。在api級別11以下，這不再被允許/可能。無論如何，這樣做是非常糟糕的做法，因爲在網絡操作正在進行時掛起UI。

使用AsyncTask並在那裏調用web服務。順便說一句。這與ksoap完全無關......任何網絡操作都會遇到這個問題。

此外，您應該升級到最新版本的ksoap2-android我剛剛發佈。 2.4.0很老，有很多問題。
