title: Start android emulator adb from Jenkins in windows (run instrumented tests, emulator does not appear)
body: <p>I would like to start emulator from Jenkins to test Android app. This is my setup of the project in jenkins and console output:</p>
  
  <p><a href="https://i.stack.imgur.com/ZwAkP.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZwAkP.jpg" alt="setup and output"></a></p>
  
  <p>When I tried Jenkins android emulator plugin with existing emulator device and his name, setup and output is here: <a href="https://i.stack.imgur.com/XtvNa.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XtvNa.jpg" alt="Jenkins emulator plugin setup and console output"></a></p>
  
  <p>The build is successful, but I cant see the running emulator when testing is running. </p>
  
  <p>Strange thing of these two options is, that when I start the command line and type these two commands, the emulator is always shown and it is running normally. But from Jenkins, in the second option I cant see it. And first option is stuck. See the screens please.</p>
  
  <p>Can somebody help me with some advice? I have tried many options and I cant figure it out.</p>
  
  <p>Many thanks :)</p>
  
  <p>P.S.: Here are the output texts (in case that somebody would like to copy it)</p>

  If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to C:\Users\josef\AppData\Local\Android\Sdk\ndk-bundle.
  If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.
