You can do with AccessToken

private AccessTokenTracker accessTokenTracker;



    accessTokenTracker = new AccessTokenTracker() {
        @Override
        protected void onCurrentAccessTokenChanged(
                AccessToken oldAccessToken, AccessToken newAccessToken) {
            updateWithToken(newAccessToken);
        }
    };




private void updateWithToken(AccessToken currentAccessToken) {

    if (currentAccessToken != null) {
        //redirect to your activity

    } else {

    // your sign in code

}

On logout you can clear the token.
