Collecting Facebook data with a Share Share

Good afternoon! I'm doing my CBT and I need urgent help! Please!

Next ... I am making my app that at the end of the application the user can share, if you want through a shareDialog of the face ... until then it is quiet ... however I wanted it when the user clicked on share .. I could collect his data such as: name, surname, age, email and location .... Do I necessarily need to make a login? my code is below:

    public class CompartilharActivity extends AppCompatActivity {


private ShareDialog shareDialog;
private CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_compartilhar);

    callbackManager = CallbackManager.Factory.create();



    shareDialog = new ShareDialog(this);  

}

public void shareLinks(View view) {

    Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.trofeu);
    if (ShareDialog.canShow(ShareLinkContent.class)) {
        ShareLinkContent content = new ShareLinkContent.Builder()
                .setContentTitle("Nome")
                .setContentDescription("Descricao")
                .setContentUrl(Uri.parse("http://site.com"))
                .build();


        shareDialog.show(content);
    }
}

What would be the best solution! Thank you!
