我正在尝试使用executeasync获取facebook的全名，但显然请求需要更长的时间，这不允许我将全名发送到下一个活动，尽管内部打印工作正常，并且名称打印正确
这是我的代码片段：

LoginManager.getInstance().registerCallback(callbackManager,
            new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(LoginResult loginResult) {
                    // App code
                    Log.d("Prova","primagetfbname");

                    AccessToken accessToken = AccessToken.getCurrentAccessToken();
                    Log.d("tokenfb",accessToken.getToken());

                    getFbName();

}

public void getFbName() {
    AccessToken accessToken = AccessToken.getCurrentAccessToken();
    Log.d("tokenfb",accessToken.getToken());

    GraphRequest request = GraphRequest.newMeRequest(
            accessToken,
            new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(
                        JSONObject object,
                        GraphResponse response) {
                    // Application code
                    try {
                        profile_name = object.getString("name");
                        Log.d("Profile name",profile_name);

                    }catch(JSONException e){
                        e.printStackTrace();
                    }

                }
            });
    Bundle parameters = new Bundle();
    parameters.putString("fields", "name");
    request.setParameters(parameters);
    request.executeAsync();
    Log.d("Prova", profile_name);
    Intent intentFacebookinfo = new Intent(getApplicationContext(), FacebookLogin.class);
    intentFacebookinfo.putExtra("FullName", profile_name);
    Log.d("Prova", profile_name);
    startActivity(intentFacebookinfo);
}
