Android App is crashing when installing through Eclipse

Question

I get the following exception every time I reinstall my through eclipse. It happens every time I reinstall an app that is currently in the foreground.

I expect that this error is only happening during development because I cause an uninstallation of a running app through Eclipse.

Has anybody seen this error on user phones?

This started happening for me as I switched to a Galaxy Nexus with ICS.

In the above logs i didn't find any thing related to my application. But still it's crashing.

Can any one tell me what's the reason for this? Is this a bug in Ice Cream Sandwich of on the Galaxy Nexus?

i got this problem when someting in XML is wrong, maybe you just have to regenerate your R.java
