title: Problems connecting Android device and running adb commands
body: <p>I'm developing an Ionic-framework app, and I have troubles running the command <strong>ionic run android</strong> which runs the apk directly on a connected Android device, it just does nothing, like in this question: <a href="https://stackoverflow.com/questions/25281711/ionic-run-android-seems-to-work-but-the-app-is-not-launched-on-the-phone-why">Ionic run android seems to work, but the app is not launched on the phone, why?</a></p>
  
  <p>So I tried to install the apk with <strong>adb install</strong> and it does nothing too.</p>
  
  <p>The only way to install an apk is to save it directly into the device and install it with packet manager.</p>
  
  <p>Other adb commands like <strong>adb usb</strong> just run and never finnish, doing nothing. The only commands that seems to work is <strong>adb logcat</strong> and <strong>adb devices</strong> which show no problem with my device:</p>
  
  <pre><code>$ adb devices -l
  List of devices attached 
  0123456789ABCDEF       device usb:2-1.5
  </code></pre>
  
  <p>I'm using: </p>
  
  <pre><code>Ionic    --version 1.3.20
  Cordova  --version 5.0.0 
  Phonegap --version 4.2.0-0.24.2
  Android device: HTC One S
  Android version: 4.1.1 HTC Sense 4+
  SO: Ubuntu 14.10 64 bits
  </code></pre>
  
  <p>I have all Android SDKs installed.</p>
  
  <p>What is the problem? </p>
