I tried use facebook credentials to log my application. i used This to develop that login. when i log using my fb account it display the my fb username. but when login using another account it display error.
This is my activity code,
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//authButton = (Button) findViewById(R.id.authButton);
// start Facebook Login
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
@SuppressWarnings("deprecation")
@Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
@Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
TextView welcome = (TextView) findViewById(R.id.welcome);
// welcome.setText("Hello " + user.getName() + "!");
welcome.setText(user.getName() + ","
+ user.getUsername() + ","
+ user.getId() + "," + user.getLink()
+ "," + user.getFirstName()+ user.asMap().get("email"));
}
}
});
}else{
Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
}
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
I want to display fb name when log in diffrent accounts.
