title: Android Studio: Failed to load dx.jar
body: <p>When I run my module in Android Studio I get this error:</p>
  
  <p>Error:Android Dex: [GradleDevBuild] Failed to load dx.jar</p>
  
  <p>I have searched endlessly for a solution online but everything is related to eclipse, there is nothing when it comes to Android Studio. </p>
  
  <p>The path to the dex.jar is C:\AndroidSdk\build-tools\26.0.0\lib\dex.jar
  So it does exists, I've moved it out of the folder and was notified that it moved so AS is aware of where it is. I have tried copying it into the root directory and into the platform-tools folder however that did nothing.</p>
  
  <p>This is the full list of errors that all seem to be stemming from this dx.jar error. </p>
