I'm pretty new here, been following bucky's videos for the last couplr of days.

I've encountered a problem while i was watching his 14th video of android development- Adding properties to widgets.

After setting background and color's color, i tried running the program.
I think it works fine, it's just that there's an error:

 13427-13456/com.example.amit.emily W/OpenGLRenderer? Failed to set EGL_SWAP_BEHAVIOR on surface 0xb3ff7480, error=EGL_SUCCESS

Can you tell me what does this mean?
How can i solve this?
