Using 1.7 requires compiling with Android 4.4 (KitKat); currently using API 14

Question

So i recently switched the target of my android project to 4.0. Now i have practically errors on every line and the error "Using 1.7 requires compiling with Android 4.4 (KitKat); currently using API 14" on the console. So my question is, how do i change this to work with api 14 and compile? thanks.
