在我的cn1應用程序中，我有一些內容我想要顯示的內容已經被格式化爲HTML，所以我認爲最好的做法是堅持使用WebView，而不是嘗試解析它並創建單獨的cn1組件爲每個段落等cn1 - webview不能正常工作

問題是，我不能說服應用程序實際顯示它。

這裏是我的代碼：

WebBrowser web = new WebBrowser(); 
web.setURL(StateMachine.URL_PREFIX + "/api/article_body.php?articleId=" + (String)map.get("id")); 
mac.findArticleBodyContainer(f).addComponent(BorderLayout.CENTER, web); 
form.revalidate();

這裏的logcat的輸出，當我打開應用程序在Android設備上（運行棉花糖，以前用棒棒糖它也不能工作，但我沒有日誌從那個）：

我還沒有嘗試過任何其他操作系統，雖然我在另一個Android設備（也棉花糖）得到相同的問題。

注意：This SO問題有答案，但對於原生Android。我沒有看到以同樣的方式從cn1訪問webview設置的方法。

更新

我感動的HTML內容的應用程序，並從本地文件加載它。我沒有從模擬器中得到任何錯誤，但沒有顯示內容。在我的Android設備，沒有任何顯示，這是來自logcat的新的輸出：

兩個相同的不祥之行是否存在：validate_display:255 error 3008和Cannot call determinedVisibility()。谷歌搜索這些似乎表明，它們出現在應用程序沒有更新某些安全措施以與Android 5.0及更高版本中使用的Linux內核兼容時出現，但可以通過在原生Android WebView上設置幾個屬性輕鬆解決。 cn1是否可以訪問這些東西，還是應該嘗試使用本地組件？
