如何在Android中使用Facebook API登出

facebook.logout(mainActivityContex);

要么

facebook.logout(this);

在Facebook SDK Facebook.java中-

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;}`
