Eclipse not recognizing my android phone - says target unknown

I am using the ADT eclipse for android development. I connected my phone then ran eclipse. Then when I run my android project, I get the window asking how you want to run it. I can see my phone listed there, but its not recognizing its target version.

As a result I am unable to run it on my phone. This is happening sometimes before, and now more often than usual.

Does anyone know how I can fix this?

Solution

Yes it's a weird one but you know how phones have "media" and "camera" mode and such, change that to "media" if I recall correctly, or "camera", it's something along those line! It was my old phone sorry, but this solved it!
