title: React-Native, Android, Genymotion: ADB server didn't ACK
body: <p>I am working with React-Native, Android, and Genymotion on Mac. When I run <code>react-native run-android</code> I get this lines at the end of the launch operation:</p>
  
  <pre><code>...
  04:54:40 E/adb: error: could not install *smartsocket* listener: Address already in use
  04:54:40 E/adb: ADB server didn't ACK
  04:54:40 E/ddms: '/Users/paulbrie/Library/Android/sdk/platform-tools/adb,start-server' failed -- run manually if necessary
  04:54:40 E/adb: * failed to start daemon *
  04:54:40 E/adb: error: cannot connect to daemon
  :app:installDebug FAILED
  
  FAILURE: Build failed with an exception.
  
  * What went wrong:
  Execution failed for task ':app:installDebug'.
  &gt; com.android.builder.testing.api.DeviceException: Timeout getting device list.
  ...
  </code></pre>
  
  <p>However, <code>adb devices</code> returns this:</p>
  
  <pre><code>List of devices attached
  192.168.59.101:5555 device
  </code></pre>
  
  <p>So far I've found no solution to run my app on the emulator. Has anyone encountered the same issue?</p>
  
  <p>Thanks,
  Paul</p>
