Downloading images with webview

This solved my problem

`          `@Override
            public boolean shouldOverrideUrlLoading (WebView view, String url) {
                boolean shouldOverride = false;
                // We only want to handle requests for image files, everything else the webview
                // can handle normally
                if (url.endsWith(".jpg")) {
                    shouldOverride = true;
                    Uri source = Uri.parse(url);
                    // Make a new request pointing to the mp3 url
                    DownloadManager.Request request = new DownloadManager.Request(source);
                    // Use the same file name for the destination
                    File destinationFile = new File (destinationDir, source.getLastPathSegment());
                    request.setDestinationUri(Uri.fromFile(destinationFile));
                    // Add it to the manager
                    manager.enqueue(request);
                }
                return shouldOverride;
            }``

make sure to add permissions for download manager, SD read, SD write!
