I have implemented a search system in my app, and the search bar appears, but when enter is pressed the search activity doesn't load.
As well as this, the text typed into the search box is black. The action bar is also black, so is there a way to make it white on API 14+?

I don't receive a force close - it just doesn't launch the search activity.
Also, what permission should I set for the final provider? The android system must be able to execute it,
