覆盖WebView发出的所有请求,并自己发出请求(最终设置代理).

码：

@Override
public WebResourceResponse shouldInterceptRequest(WebView view,String url) {
    if (url == null || url.trim().equals(""))
        return null;

    final DefaultHttpClient httpClient = new DefaultHttpClient();
    httpClient.getConnectionManager().closeExpiredConnections();
    final HttpUriRequest httpRequest = new HttpGet(url);

    try {
        final HttpResponse response = httpClient.execute(httpRequest);
        final Header[] headers = response.getHeaders(CONTENT_TYPE);
        String mimeType = "";
        String encoding = "";
        if (headers != null && headers.length > 0) {
            final String type = headers[0].getValue();
            final int semicolonIndex = type.indexOf(';');
            if (semicolonIndex != -1) {
                mimeType = type.substring(0,semicolonIndex).trim();
                encoding = type.substring(semicolonIndex + 1).trim();
                final int equalsIndex = encoding.indexOf('=');
                if (equalsIndex != -1)
                    encoding = encoding.substring(equalsIndex + 1).trim();
            } else
                mimeType = type;
        }

        return new WebResourceResponse(mimeType,encoding,response.getEntity().getContent());
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } finally {
        httpClient.getConnectionManager().closeExpiredConnections();
    }
    return null;
}

所有这些请求似乎都很好,但是最终我得到了以下两个问题之一的堆栈跟踪：

3 15:07:28.650 E/InputDispatcher( 3981): channel '40d76268 com.secure.browser/com.secure.browser.SecureBrowserActivity (server)' ~ Consumer closed input channel or an error occurred.  events=0x8
01-03 15:07:28.650 E/InputDispatcher( 3981): channel '40d76268 com.secure.browser/com.secure.browser.SecureBrowserActivity (server)' ~ Channel is unrecoverably broken and will be disposed!

这显然是指示文件描述符(fid)中的操作系统耗尽的

要么

01-03 15:29:36.810 I/DEBUG   ( 5798):     5903cd34  ac81c0b7  /system/lib/libdvm.so
01-03 15:29:38.380 I/DEBUG   ( 5798): debuggerd committing suicide to free the zombie!
01-03 15:29:38.380 I/BootReceiver( 3981): Copying /data/tombstones/tombstone_07 to DropBox

(SYSTEM_TOMBSTONE)

这意味着我认为这意味着操作系统正在处于低级问题.

我使用3.0,所以应该支持该功能.

当我打开javascript,或者浏览一段时间后没有javascript,这大部分失败.
