在使用Android WebView实现简易浏览器时遇到文件上传功能异常。当选择图片后，无法将路径填充到<input type=file/>中。日志显示路径值存在，但回调未能正确处理。

使用系统自带的webview做了个简单的浏览器，在使用<input type=file/>上传图片的时候出了问题，图片选择对话框能正常显示和选择，可是选择完成后不能把选择的图片路径填到 file输入框里， Log输出里显示是有值的，谁能帮忙看看，我用的是android2.2的IDE, SDK版本是 16 - 23

代码：

Log.i("UPFILE","onActivityResult");



        if(null == mUploadMessage) return;

        if(null==data) return;

        if(resultCode==Activity.RESULT_CANCELED) return;



        Uri result = getUrl(data);

        if(null==result) return;



        if(mUploadCallback!=null){

            Log.i("UPFILE", "mUploadCallback after parser uri:" + result.toString());

            mUploadCallback.onReceiveValue(new Uri[]{result});

        }else {

            Log.i("UPFILE", "mUploadMessage after parser uri:" + result.toString());

            mUploadMessage.onReceiveValue(result);

        }

        mUploadCallback= null;

        mUploadMessage = null;
