在我的 phonegap 项目中，我有两个活动，Mainactivity 和 Secondactivity，我为 Mainactivity 编写了一个插件来使用 Intent 启动 Secondactivity。我总是失败并得到一些错误日志：

08-28 12:11:07.298: W/webcore(924): java.lang.Throwable: EventHub.removeMessages(int what = 107) is not supported before the WebViewCore is set up.

08-28 12:12:06.738: E/CordovaWebView(924): CordovaWebView: TIMEOUT ERROR!

并得到：

CordovaWebViewClient.onReceivedError: Error code=-6 Description=The connection to the server was unsuccessful. URL=file:///android_asset/www//Second.html

如果我使用 codorva 1.8.1 我得到：

08-28 15:13:03.020: W/webcore(29758): java.lang.Throwable: EventHub.removeMessages(int what = 107) is not supported before the WebViewCore is set up.
08-28 15:13:22.850: W/webview(29758): java.lang.Throwable: Warning: A WebView method was called on thread 'Thread-7765'. All WebView methods must be called on the UI thread. Future versions of WebView may not support use on other threads.

这是我的 SecondActivity 代码：

public class Secondactivity extends DroidGap {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.init();
        super.setIntegerProperty("loadUrlTimeoutValue", 60000); 
        super.loadUrl("file:///android_asset/www//Second.html");
    }
}

我的 Mainactivity 还扩展了 DroidGap。

谁能给我一些提示？

===============================================我用startActivityForResult替换了startActivity ，这行得通！

您必须打开 second.html 的 index.html 文件，并在 index.html 文件中管理第二个活动

更改此行。

 super.loadUrl("file:///android_asset/www/Second.html");

这里有错误//Second.html
