Android的Http請求鑄造錯誤

-1

我停留在那個一直給我一個鑄造錯誤此HTTP請求的文件。我是新來登錄在網絡上，所以我也跟着說已經過時代碼的HttpParams進口的教程，我在這裏找到一個解決方案要求我導入和包括來自cz.msebera.android.httpclient依賴作爲片段婁代碼，但現在我得到一個鑄造錯誤我不明白。任何幫助，這將不勝感激。我的Android應用程序是用戶登錄和註冊Android的Http請求鑄造錯誤

}

的錯誤我得到這個樣子的

當問問題，請格式化爲最大的可讀性（感謝@ martijnn2008）代碼/日誌，請從乞求不要緊迫性 - 它對**志願者**來說並不緊急。 – halfer

HttpParams httpRequestParams = (HttpParams) new BasicHttpParams(); 
(...) 
HttpClient client = new DefaultHttpClient((ClientConnectionManager) httpRequestParams);

除非BasicHttpParams是ClientConnectionManager的一個子類（這可能並非如此），那麼你肯定會在這裏得到一個ClassCastException！鑄造「參數」的「連接管理器」沒有多大意義，我:-)
