WebView Cache无法在Android 4.4中运行

我一直致力于一个从Web缓存图像的应用程序,即使在用户离线时也会显示它.在Android 4.4问世之前,这种方法运行良好.现在,我看到的只是一个"无法加载网页"错误.我想它可能需要做一些事情,Kitkat使用Chromium来加载webview,但我不太确定.对此有任何修复？

这是我的代码:

mWebView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
mWebView.setWebViewClient(new MyWebViewClient());

mWebViewSettings = mWebView.getSettings();
mWebViewSettings.setJavaScriptEnabled(true);
mWebViewSettings.setAllowFileAccess(true);
mWebViewSettings.setAppCacheEnabled(true);
if (Build.VERSION.SDK_INT < 18)
    mWebViewSettings.setAppCacheMaxSize(5 * 1024 * 1024); // 5MB
mWebViewSettings.setLoadsImagesAutomatically(true);
mWebViewSettings.setAppCachePath(getActivity().getApplicationContext()
        .getCacheDir().getAbsolutePath());
mWebViewSettings.setBuiltInZoomControls(true);
if(Build.VERSION.SDK_INT<=18)
    mWebViewSettings.setDefaultZoom((WebSettings.ZoomDensity.FAR));
mWebViewSettings.setUseWideViewPort(true);
mWebViewSettings.setLoadWithOverviewMode(true);

            "AHSelectionPreffs",
                    Context.MODE_PRIVATE);
    Date CAMPUS_MAP_LAST_UPDATE_DATE = new Date();
    String CAMPUS_MAP_LAST_UPDATE_DATE_STRING = MyPrefs
                .getString("CAMPUS_MAP" + String.valueOf(StorageHelper.ID), null);

    SimpleDateFormat simpleDateFormatter = new SimpleDateFormat(
                            "EEE MMM dd HH:mm:ss zzz yyyy", Locale.US);

    if (CAMPUS_MAP_LAST_UPDATE_DATE_STRING != null) {
        try {
            CAMPUS_MAP_LAST_UPDATE_DATE = simpleDateFormatter
                    .parse(CAMPUS_MAP_LAST_UPDATE_DATE_STRING);

        } catch (ParseException …

Android应用程序签名:Proguard返回错误代码1.请参阅控制台

我已经构建了一个使用JacksonJson作为库的应用程序.我试图将其导出为已签名的应用程序并获取proguard错误.我尝试过在互联网上发布的各种解决方案,但似乎都没有.任何帮助将不胜感激.
