    In latest android versions we cant access resources such as assets , files from storage. https://developer.android.com/reference/androidx/webkit/WebViewAssetLoader is best guide to proceed. WebViewAssetLoader and its internal classes helps to access them.

    you can check the below sample code.

        final WebViewAssetLoader assetLoader = new WebViewAssetLoader.Builder()
            .addPathHandler("/assets/", new WebViewAssetLoader.AssetsPathHandler(this)) //****for assets****
            .addPathHandler("/images/", new WebViewAssetLoader.InternalStoragePathHandler(context, getFilesDir()))//****for files****
            .build();

    webView.setWebViewClient(new WebViewClient() {
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view,
                                                          WebResourceRequest request) {
            return assetLoader.shouldInterceptRequest(request.getUrl());
        }
    });

    String assetsPic = "<img width='42px' height='58px' src='https://appassets.androidplatform.net/assets/pic.png'/>";
    String storagePic = "<img width='42px' height='58px' src='https://appassets.androidplatform.net/images/pic.jpg'/>";
    webView.loadData(assetsPic+"<br>"+storagePic, "text/html", "UTF-8");

    Put the images in your assets folder. Then use the corresponding prefix

    file:///android_asset/

    Try like this

    String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
String imagePath = "file://"+ base + "/image_name.jpg";
String html = "<html><head></head><body> <img src=\""+ imagePath + "\"> </body></html>";
webView.loadDataWithBaseURL("", html, "text/html","utf-8", "");

    The problem was in the file path

    file:///storage/emulated/01484890695248.jpg

    would be 

    file:///storage/emulated/0/01484890695248.jpg

    Thanks @Charuක for the help..
