title: Cannot run adb from terminal in Ubuntu
body: <p>I am new to Ubuntu. I cannot run <code>adb</code> in my terminal. When I try to run <code>adb</code> in the terminal I get the following error: </p>
  
  <pre><code>No command 'adb' found
  </code></pre>
  
  <p>At the same time I can run my Android application in the emulator.  What can be the problem?</p>
