本文探讨了Android应用在启动时遇到的Java.lang.RuntimeException异常，特别是当应用图标使用的PNG图像资源未找到时的问题。通过分析，发现删除gen/和bin/目录的内容可以解决此问题。此外，还遇到了在开发过程中由于更改布局文件导致的运行时错误，如缺失组件或ID错误。解决这些问题的方法包括确保所有资源文件正确引用和布局文件的正确性。

E/AndroidRuntime( 1046): java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.example.hellomapview/com.example.hellomapview.HelloMapActivity}:
android.content.res.Resources$NotFoundException: File res/drawable/red.png from xml
type layout resource ID #0x7f020000

I added a png image to be used as an icon for the application. When debugged andinstalled, the icon appeared fine on the device, but the application wouldn't startand it raised a "resource not found" exception for the image. Deleting the contentsof the gen/ and bin/ directories does solve the problem.I've also experienced this problem when I changed the xml layout files a few timesduring development. The application sometimes raises runtime exceptions about missingwidgets or wrong IDs that are neither missing nor wrong. And again, deleting thecontents or gen/ and bin/ solves the problem.This really needs to be fixed since it drove me crazy to see that my applicationwasn't working and my code was perfectly fine. It took me a while to find this pageand figure out what I should do to fix it.
