在为 Braintree 导入 CN1Lib 并设置我自己的 Braintree 服务器后，我准备实现 Braintree API 的客户端。我查看了 Codenameone 的 GitHub for Braintree 并按照说明使用了他们的教程代码。当我在按钮的 Actionlistener 方法下插入这段代码时，我运行了我的应用程序并收到错误:java.lang.ClassNotFoundException: com.codename1.braintree.impl.BraintreeNativeImpl

查看控制台跟踪错误，发现在jsProxy.set("onSuccessNonce", new JSFunction()这一行(代码中这一行也是用**括起来的下)

    }

    public interface Callback {
        String fetchToken();

        void onPurchaseSuccess(String var1);

        void onPurchaseFail(String var1);

        void onPurchaseCancel();
    }
}

我一直在尝试寻找解决方案，但想不出任何解决方案。有谁知道如何解决此错误？

最佳答案

您应该删除所有这些并使用代号一设置中的扩展管理器安装 cn1lib。

  • 右键单击该项目
  • 选择代号一 -> 代号一设置
  • 扩展
  • 输入 Braintree，点击“下载”
  • 右键单击该项目
  • 选择Codename One -> Refresh cn1libs

API 应该“正常工作”。

如果您想从代码开始工作，您还需要复制项目中的所有 native 代码并查看属性文件以将其合并到您的项目设置中。

或者，您也可以只下载项目并使用 ant 或 NetBeans 构建 cn1lib。
