How to exit facebook api application in android

Question

I am using facebook api for android using facebook developer guide. I was able to implement login for facebook api for Android. I want to implement a logout function. I tried the developer guide, but I don’t know which place I need to implement. I will be grateful if you guys can help me with this code.

public class FacebookandroidsdkActivity extends Activity { /** Called when the activity is first created. */ Facebook facebook = new Facebook("252039928190210"); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); facebook.authorize(this, new DialogListener() { @Override public void onComplete(Bundle values) {} @Override public void onFacebookError(FacebookError error) {} @Override public void onError(DialogError e) {} @Override public void onCancel() {} }); } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); facebook.authorizeCallback(requestCode, resultCode, data); } } 

Answer 1

 facebook.logout(mainActivityContex); 

or

 facebook.logout(this); 

Facebook SDK Facebook.java --`

 public String logout(Context context) throws MalformedURLException, IOException { Util.clearCookies(context); Bundle b = new Bundle(); b.putString("method", "auth.expireSession"); String response = request(b); setAccessToken(null); setAccessExpires(0); return response; }` 

Answer 2

 public String logout(Context context) throws MalformedURLException, IOException { Util.clearCookies(context); Bundle b = new Bundle(); b.putString("method", "auth.expireSession"); String response = request(b); setAccessToken(null); setAccessExpires(0); return response; }

Answer 3

using 3.1 sdk you can call Session.getActiveSession (). closeAndClearTokenInformation ()

Answer 4

There is a .logout () method in this Facebook class, if I remember correctly. I think you are looking for this.
