title: signingConfig.storeFile does not exist when I try to run the project
body: <p>I downloaded a project from GitHub and opened it by Android Studio. All required build tools and Android support repositories were automatically downloaded through Android Studio.</p>
  
  <p><a href="https://github.com/DrKLO/Telegram" rel="nofollow noreferrer">https://github.com/DrKLO/Telegram</a></p>
  
  <p>Now that I try <strong>to run the project</strong>, I get an error in Massages.</p>
  
  <pre><code>Error:A problem was found with the configuration of task ':TMessagesProj:packageDebug'.
  &gt; File 'G:\AndroidDev\AndroidStudioProjects\Telegram-master\TMessagesProj\config\release.keystore' specified for property 'signingConfig.storeFile' does not exist.
  </code></pre>
  
  <p>I found some other threads on Stack Exchange:</p>
  
  <p><a href="https://stackoverflow.com/questions/21780847">Gradle signing app with packageRelease “specified for property &#39;signingConfig.storeFile&#39; does not exist”</a></p>
  
  <p><a href="https://stackoverflow.com/questions/25211444">Android specified for property &#39;signingConfig.storeFile&#39; does not exist</a></p>
  
  <p>and I created the keystores as they suggested, but I'm still getting that error when I click the run button. They seem to be different from mine.</p>
  
  <p>I also generated the signed APK and when I tried to install it on a device, the program crashed and stopped and I guess it might be caused by the mentioned problem.</p>
  
  <p>I'm sure it should work correctly because it's the official source of Telegram messenger. <a href="https://github.com/DrKLO/Telegram" rel="nofollow noreferrer">https://github.com/DrKLO/Telegram</a></p>
