Android - Java - 意图发送 facebook 聊天消息（facebook 禁用 xmpp）

Question

***Facebook deprecated xmpp api.

Is there a way to open an intent (or pass data to fb) to send chat message on android device? Facebook & Messenger apps installed on the device.

Thanks :-)

Answer 1

You need to pass uri to the intent Here 100005727832736 is the user id of the person who you want to message to

Uri uri = Uri.parse("fb-messenger://user/100005727832736");

Here is my sample code

Uri uri = Uri.parse("fb-messenger://user/100005727832736");

Intent toMessenger= new Intent(Intent.ACTION_VIEW, uri);
try {
        startActivity(toMessenger);
    } 
catch (android.content.ActivityNotFoundException ex) 
    {
        Toast.makeText(context, "Please Install Facebook Messenger",    Toast.LENGTH_LONG).show();
}
}

This is what worked for me and i haven not tested this for some time now.

Answer 2

To launch facebook app let urlString = "fb://page/your_fb_page_id"

To launch facebook messenger let urlString = "fb-messenger://user/your_fb_page_id"

FB page id is usually numeric. To get it, goto Find My FB ID input your profile url, something like www.facebook.com/edgedevstudio then click "Find Numberic ID".

Voila, you now have your fb numeric id. replace "your_fb_page_id" with the generated Numeric ID

 val intent = Intent(Intent.ACTION_VIEW, Uri.parse(urlString))
 if (intent.resolveActivity(packageManager) != null) //check if app is available to handle the implicit intent
 startActivity(intent)
