I develop an news android application. In news detail screen in the webview component have a "facebook share" button. When application runs Activity_Create sub routine in news detail activity then msgbox appears as "01.png". And added to webview html to this code. When I click the button in the webview appear as "03.png". And when click to share button error screen appears as 04.png. I cannot share to link. What must I do for share links?
