启动画面后应用程序关闭

Question

您好，我实现了一个启动画面，在我的主要课程之前启动。令我惊讶的是，我的启动画面加载后，它强制关闭我的应用程序logcat错误：说没有找到类，如果我确定我已经在我的manifest中声明了它，我已经完成了。我不知道我错在哪里，还有我错过了什么。请帮忙 。

Answer 1

您将INTRO活动定义为错误（您忘记了NugaBest包）。 试试这个：

<activity 
      android:name="helog.diwesh.NugaBest.NUGA_HealthCareActivity_Intro" 
      android:label="NUGA_HealthCareActivity_Intro" /> 

希望这有助于！
