java - ActivityNotFoundException 错误

Question

此问题适用于显示网站图像和描述的应用程序，当单击 ListView 时，与该描述相关联的网站会在浏览器中打开。

但是当我点击其中一个时出现错误。我不知道如何解决它，我们将不胜感激。

这是错误堆栈:

Answer 1

您是否尝试过将http:// 或https:// 放入URL 资源？

示例:代替 google.com，http://google.com

我认为，此更改将解决此异常:

E/MessageQueue-JNI:android.content.ActivityNotFoundException:找不到处理 Intent 的 Activity { act=android.intent.action.VIEW dat=google.com }
