I would ignore that. The message you are seeing is important on phones but not in the emulator. The emulator is extremely slow. Nothing you are doing is resource intensive so your application should perform nominally on a device.

On a device you can use developer options, on some phones, to enable a visible signal that you may be doing too much work in the foreground. On my Galaxy Nexus I can navigate to Settings > Developer Options > Strict mode enabled. Checking that box will causes a red border to flash around any application when it causes a message like what you posted from your logcat to occur.

The solution for removing the warning is threading but I feel you may be devoting effort to a non issue. Only way to know is device testing.
