android - 在 Android 应用程序中集成 Facebook+Parse 时出错

Question

这是我将 Facebook 与 Android 应用程序 (parse.com) 集成的代码。

请在下面找到代码和堆栈跟踪。此处尝试通过解析对 FB 用户进行身份验证。

当您单击 login with Facebook 选项时，应用程序崩溃。任何建议将不胜感激。

private void onLoginButtonClicked() {
        // TODO Auto-generated method stub
        LoginActivity.this.progressDialog = ProgressDialog.show(
                LoginActivity.this, "", "Logging in...", true);
        List<String> permissions = Arrays.asList("basic_info", "user_about_me",
                "user_relationships", "user_birthday", "user_location");

        // ParseFacebookUtils.initialize(appId);
        ParseFacebookUtils.logIn(permissions, this, new LogInCallback() {
            @Override
            public void done(ParseUser user, ParseException err) {
                LoginActivity.this.progressDialog.dismiss();
                if (user == null) {
                    Log.d(IntegratingFacebookTutorialApplication.TAG,
                            " user cancelled the Facebook login.");
                } else if (user.isNew()) {
                    Log.d(IntegratingFacebookTutorialApplication.TAG,
                            "User signed up and logged in through Facebook!");
                    showUserDetailsActivity();
                } else {
                    Log.d(IntegratingFacebookTutorialApplication.TAG,
                            "User logged in through Facebook!");
                    showUserDetailsActivity();
                }
            }
        });
    }

Answer 1

你必须调用它

ParseFacebookUtils.initialize(appId);

之前

ParseFacebookUtils.logIn();
