我正在尝试使用robolectric进行测试并获取下面的错误。看起来像其他人在create()后添加一个Intent时收到了这个错误,但我根本没有在操作这个intent。也许我需要为此做一些特殊的事情,因为它使用了片段,但这只是一个猜测。任何帮助或方向将不胜感激。使用robolectric测试我的MapActivity

感谢您的帮助。我试图实现你在说什么,但我仍然遇到同样的错误。这里是我更新的代码:https://gist.github.com/anonymous/9120783 –
Erik,不要在你的自定义阴影中扩展ShadowMapActivity,因为在这种情况下,调用super .__构造函数__();在你的影子里不会有任何影响。在ShadowMapActivity中,这个方法只是空白。从这里获取代码https://github.com/robolectric/robolectric/blob/master/src/main/java/org/robolectric/shadows/ShadowMapActivity.java重命名类名并添加更改。 –
