Android : Find streaming video in webview

Actually my goal is to implement a webview and catch the url of streaming video in webview. I tried so many codes but no result. Here my code i tried so far final class MyWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if (url.endsWith(".mp4") { Intent intent = new Intent("android.intent.action.VIEW", Uri.parse(url)); view.getContext().startActivity(intent); return true; } else { return super.shouldOverrideUrlLoading(view, url); } } }
