sample android app does not deploy in android device
<p>I'm just starting to learn developing in android. I'm following the nativescript getting started guide but can't seem to proceed. It mentions to run <strong>tns run android</strong> while the phone is connected. but this doesn't seem to work. USB debugging is enabled on my phone and developer options.</p>

<p>at this point the project builds but does not appear on my phone. (I tried using the genymotion emulator before, maybe I'm wrong with my assumption that it would just appear in my android phone just like how genymotion does it)</p>

<p>check with tns devic command, it detects my android phone but says unreachable. what does that mean?
also would there be other specific options in my phone that I need to set in order to have this app deployed on my phone?</p>
