Android Main thread too much work

I'm building my first app, but after adding a few layout stuff a DrawerLayout to be exact it started to give me an error:

I/Choreographer: Skipped 126 frames! The application may be doing too much work on its main thread

This here is my layout code:

<!-- The main content view -->
