WebView Desktop Mode Error Open Link in Browser

Help me to solve my exercise. I make WebView app that showing WhatsApp Web QR Code in Desktop Mode, QR Code not showing in Mobile View.

I have success to open WhatsApp Web in WebView in Desktop Mode. But when you click a link in it, it changes to Mobile View. My idea is to open link in browser, not in WebView. Everythings fine, but when you close the app then open it again, it directly open WhatsApp Web in browser.

This is my app source code, including :

• progress bar
• ads
• desktop mode (user agent string)
• open link in browser

Can you help me?
