shouldOverrideUrlLoading(WebView view, String url) working on android 4.3 and below. but not working on android 4.4 (Kitkat)

Below code written inside shouldOverrideUrlLoading(WebView view, String url) working on android 4.3 and below. but not working on android 4.4 (Kitkat). while debugging I found shouldOverrideUrlLoading() not called when I clicked on pdf link, but called on every link that not contain file. Please help thanks in advance...

if(url.contains(".pdf")){ try{

Intent browserIntent = new Intent(); browserIntent.setAction(Intent.ACTION_VIEW); browserIntent.addCategory(Intent.CATEGORY_BROWSABLE); browserIntent.setData(Uri.parse(url)); startActivity(browserIntent);

}catch(){ }
