and now i am getting this

07-04 00:28:31.914: ERROR/ActivityManager(101): fail to set top app changed!

the XML declaration

is saying in the packages com/pocketjourney/view there will a class called TransparentPanel

so I assume your package isn't that, you will have named it yourself so you need to update your XML

com.your.package.TransparentPanel
