Why isn't my Android app working when I test it on a real device?
<p>I'm building an Android app with Ionic Framework, and am trying to run it on a real device with USB debugging, like in these tutorials:</p>

<p><strong>Step-1</strong></p>

<blockquote>
  <p><code>$ ionic platform add android</code></p>
  
  <p><code>$ ionic build android</code></p>
</blockquote>

<p>After adding the Android platform and building an APK with the above commands, it works correctly with no error. So, I try the next step:</p>

<p><strong>Step-2</strong></p>

<p>I connected device and PC via Debugging mode to run android devices. I ran the command <code>ionic run android</code>. I get the below error messageL</p>

<blockquote>
  <p><code>$ ionic run android</code></p>
  
  <p><code>ANDROID_HOME=C:\Android\sdk
  JAVA_HOME=C:\Program Files\java\jdk1.8.0_25
