title: Android Studio : Unable to recreate missing debug keystore
body: <p>I'm sorry if this question is duplicate, but I have spent a few days finding solution to the problem and couldn't find one, also I can't comment in the existing question so I decided to ask a new one.<br/>
  When I try to run my app in Android Studio I have this error:</p>
  
  <pre><code>Error:Execution failed for task ':app:validateDebugSigning'.
  &gt; Unable to recreate missing debug keystore.
  </code></pre>
  
  <p>As far as I know, the keystore file is located in the folder (user)/.android (I'm using Windows 8.1) but there IS a keystore file in this folder.<br/><br/>
  <strong>WHAT I HAVE TRIED:</strong><br/>
  - I deleted the old keystore file and tried to create a new one by running the app in Android Stuidio but like the error said, it couldn't create keystore file. <br/>
  - I managed to create a new keystore file by running the app in Eclipse, this is the ddms.cfg file:<br/></p>

  <p>I also checked the permission of the .android folder, all permissions are allowed.<br/>
  Still, I have the same error when I try to run the app.<br/>
  Hope someone can help me.<br/>
  (I know there already is a question with the same title but I couldn't understand the answer, also I can't comment to ask)</p>
