title: How to get Device Id from adb
body: <p>Could you tell me how to get device Id  from adb command?</p>
  
  <p>I tried:
  adb logcat > file.txt<br>
  but I can't find it. ( I search by 'device id', 'test', 'ads' and few other)</p>
  
  <p>I need it this ID to put my device to TEst devices list because I need to test Ads from AdMob.</p>
  
  <p>Thanks</p>
