致命异常AsyncTask#1安卓Watson翻译器

Question

当我点击应用程序中的翻译按钮时，我不断收到以下异常：我已经确认我的watson APi密钥是正确的。。

我使用watson Translator Api只翻译我数据库中的特定短语。。。所有的数据库方法都很好——我只是在翻译任务中出现了一个错误。

这是我的TranslatorClass

Answer 1

快速检查显示身份验证和服务URL都参考了Visual Recognition。不确定这是否是问题所在，但API密钥和URL是特定于服务的，除非您在服务之间共享信息。

如果您还没有，请查看API参考资料中的详细信息

Answer 2

我的android Studio版本出现问题，导致此错误。
