I can get the user id in the application with a graph-api in my application. Then, how to open the Messenger chat window on Facebook using the application id in Android.
We can open the messenger facebook chat window using global-facebook-id (using intent and uri).
Uri uri = Uri.parse("fb-messenger://user/");
uri = ContentUris.withAppendedId(uri, Long.parseLong(peopleId));
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
But it is not possible to get the global-facebook id using app-scoped-id.
Then, I want to know how to open the Messenger chat window for Facebook using only the application identifier. I don’t need to send a personal message, only opening is all I need.
Thanks for your reading!
