Note   Make sure internet permission is given   In android 9 0   Webview or Imageloader can not load url or image because  android 9 have network security issue which need to be enable by manifest file for all sub domain  so either you can add security config file    Add  xml network security config into your resources     x000D   x000D   lt network-security-config gt  x000D       lt domain-config cleartextTrafficPermitted  true  gt  x000D       lt domain includeSubdomains  true  gt www google com lt  domain gt  x000D       lt  domain-config gt  x000D   lt  network-security-config gt  x000D   x000D   x000D     Add this security config to your Manifest like this     x000D   x000D   lt application x000D      x000D      android networkSecurityConfig   xml network security config  x000D          gt  x000D   lt  application gt  x000D   x000D   x000D    if you want to allow all sub domain    x000D   x000D   lt application x000D     android usesCleartextTraffic  true  x000D          gt  x000D   lt  application gt  x000D   x000D   x000D    Note  To solve the problem  don t use both of point 2  android networkSecurityConfig   xml network security config  and android usesCleartextTraffic  true   choose one of them

Just as an alternative solution   For me webView getSettings   setUserAgentString  Android WebView   did the trick   I already had implemented INTERNET permission and WebViewClient as well as WebChromeClient
