You should override the shouldOverrideUrlLoading method of WebViewClient @Override public boolean shouldOverrideUrlLoading (WebView view, String url) { if(flag) { URL aURL = new URL(url); URLConnection conn = aURL.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); // read inputstream to get the json.. … … return true; } return false } @override public void onPageFinished (WebView view, String … Read more
You can do this without any Java code using the design library’s CoordinatorLayout and NestedScrollView, with app:layout_scrollFlags set on Toolbar.

The JPEG format does not support alpha transparency, which is why the transparent background becomes black when you convert your original image to JPEG. Use the PNG format instead: map1.compress(Bitmap.CompressFormat.PNG, 100, baos); and String imgTag = “<img src=”data:image/png;base64,” + imgToString + “” align=’left’ bgcolor=”ff0000″/>”;

This means no sync is required and HttpURLConnection uses the same cookie storage as the WebViews. Class WebkitCookieManagerProxy: import java.io.IOException; import java.net.CookieManager; import java.net.CookiePolicy; import java.net.CookieStore; import java.net.URI; import java.util.Arrays; … Read more
