I'm succesfully using Facebook share method on my webapp like so using the FB JS SDK.
FB.ui({
method: 'share',
href: 'https://myapp.com',
})
However if a user access my webapp using mobile device it requires them to login to facebook through browser even if they have the main facebook app installed on the device. Is it possible to launch share dialog using native facebook app with intent if available and if not fallback to facebook in browser to share.
