String baseUrl = "file:///android_asset/folder1/";
webView.loadDataWithBaseURL(baseUrl, readFileAsString("index.html") , mimeType, "UTF-8", null);
But images don't loading.
If I put images to "assets" directory (MyProject/assets/) and make baseUrl = "file:///android_asset" images are loaded correctly;
How load images not only from root assets directory, but and from assets/folder1?
                I saw a long post about this subject a while ago. If you still need some help with it look it up. devblog.morethanheroic.com/2017/01/03/…

String html = "<html><head><title>TITLE!!!</title></head>";
html += "<body><h1>Image?</h1><img src=\"icon.png\" /></body></html>";
webview.loadDataWithBaseURL("file:///android_res/drawable/", html, "text/html", "UTF-8", null);

                The baseURL lets you to run all the files such as .js/.css/.html files from their folders. For example, there is a folder and all .js/.css/.html files in it, and you call .html files where you locate the folder address as called baseURL: webview.loadDataWithBaseURL("file:///android_asset/myWebFilesInThisFolder/", "<html><body><p>hello world</p></body></html>" So, you don't have to write a full address for JS/CSS/HTML just bundle it!

                @Janmejoy FYI the second link (LoadDataWithBaseurl) is pointing to http://lomza.people.totem-soft.com/?p=62 which seems to be an invalid location.

I think you have to set the base to assets and add the sub folders to your image src's like this:
webView.loadDataWithBaseURL("file:///android_asset/", readAssetFileAsString("folder1/index.html"), "text/html", "UTF-8", null);
Html:
<img src="folder1/image1.jpg">
This worked for me on Android 5.1
private String readAssetFileAsString(String sourceHtmlLocation)
    InputStream is;
        is = getContext().getAssets().open(sourceHtmlLocation);
        int size = is.available();
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();
        return new String(buffer, "UTF-8");
    catch(IOException e)
        e.printStackTrace();
    return "";
                added method code, this code was previously taken from another SO post but unfortunately I don't have the link to credit them

            bitmap = BitmapFactory.decodeFile(filePath);
            Log.v("Image data-->", "" + bitmap);
            imageWidth = bitmap.getWidth();
            imageHeight = bitmap.getHeight();
            Log.e("Width", "" + imageWidth);
            filePath = "file://" + filePath;
            String html = "<html xmlns=\"http://www.w3.org/1999/xhtml\"><head><meta http-equiv=\"Content-Type\" content=\"text/html\";charset=utf-8\"/><title></title></head><body style=\"width:"
                    + imageWidth
                    + "px; height:"
                    + imageHeight
                    + "px; background:url("
                    + filePath
                    + ") no-repeat; position:relative;\">"
                    + getDivTag(mapList)
                    + "</body></html>";
            Log.v("MIS", "" + html);
            webview.getSettings().setSupportZoom(true);
            webview.loadDataWithBaseURL(null, html, "text/html", "utf-8", null);
            System.out.println(html);
        } catch (Exception e) {
            e.printStackTrace();
                Seriously? if He says putting them in one folder works well means he must have put the permission.

                @Darpan The answer is totally irrelevant so is your comment. This works because OP's assets are local and don't need the internet permission. Simply, "he must have put the permission." is invalid argument
