Android与H5交互，数据不同步

问题：

我直接在nativeAction的方法下吊起一个下载方法，导致了下载回调

start(DownloadObservable o, final String url)

函数中无论对

H5ReportBean h5Data = downloadData.get(url);

的h5Data怎么修改，在其它函数（success、fail、update）都不起作用，get出的数据仍是修改前的数据

private Map<String, H5ReportBean> downloadData = new HashMap<>();

@JavascriptInterface
    public void nativeAction(final String json) {
        final H5ReportBean bean = H5DataParse.convert(json);
        DownloadServices.getInstance().download(bean.getDownloadUrl(), getContext(), bean.getAppName());
        if (!downloadData.containsKey(bean.getDownloadUrl())){
            downloadData.put(bean.getDownloadUrl(), bean);
        }
    }

new DownloadObserver() {
            @Override
            public void start(DownloadObservable o, final String url) {

                H5ReportBean h5Data = downloadData.get(url);
                if (null != h5Data) {
                    int id = (int) System.currentTimeMillis();
                    h5Data.setTmpNotifactionId(id);
                    NotificationUtils.sendNotification(getContext(), id, h5Data.getAppName(), "开始下载...");
                }
            }

            @Override
            public void success(DownloadObservable o, final String url) {
                H5ReportBean h5Data = downloadData.get(url);
                if (null != h5Data && null != h5Data.getTmpNotifactionId()) {
                    Integer id = h5Data.getTmpNotifactionId();
                    NotificationUtils.sendNotification(getContext(), id, h5Data.getAppName(), "下载成功");
                    downloadData.remove(url);
                }
            }

            @Override
            public void fail(DownloadObservable o, final String url) {
                H5ReportBean h5Data = downloadData.get(url);
                if (null != h5Data && null != h5Data.getTmpNotifactionId()) {
                    Integer id = h5Data.getTmpNotifactionId();
                    NotificationUtils.sendNotification(getContext(), id, h5Data.getAppName(), "下载失败");
                    downloadData.remove(url);
                }
            }

            @Override
            public void update(DownloadObservable o, final String url, final int progress) {

                H5ReportBean h5Data = downloadData.get(url);

                if (null != h5Data&&null!=h5Data.getTmpNotifactionId()) {
                    Integer id = h5Data.getTmpNotifactionId();
                    NotificationUtils.sendNotification(getContext(), id, h5Data.getAppName(), progress + "%");
                }
            }
        };
        DownloadServices.getInstance().addObservers(mObserver);

通过打印线程id

android.os.Process.myTid()

来判断自己的方法在哪个线程中

无脑的方法可以这样使用

 /**
     * 这个不是UI线程，这里定义的数据，主线程不会共享
     *
     * @param json
     */
    @JavascriptInterface
    public void nativeAction(final String json) {

       
//        h5Action(tjson);

        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                h5Action(tjson);
            }
        });

    }
