I follow the steps but it's not working for me

Hi Sameer49, all
I follow step by step then try to represent the example like youtube video.

My last step is that sending java -jar gmail_example to command line.
It could catch my device and emulator correctly like video, but my device or emulator just freeze not working

Seems not working for me. Wonder why and how to do so.
Could anyone help me out.

Thanks
Newman
