Is internet necessary to run android application

I'm very first for Android. I just tried to run the Hello word application using emulator But doesn't launch emulator even after 20 minutes.

My console is idle after this:

I am having poor internet connection today,is this reason ? Any other problem

Help me to recover from confusion ! Thanks

No Internet isn't necessary at all.
There must be something else. Did you see logcat? what does it say?

Do you start AVD emulator separately, before you start your application to run it on the AVD. And to start AVD you don't need I-net connectivity, it's required when your application does something with external web content.

This logcat are display that your project run normally.and one more thing is that in this hello word you not require any internet connection

Internet isn't necessary! To see in Logcat, click Window -> Show View -> Logcat (If its not there, find in Other). And copy paste the things which are in Red color..
