title: How can i upload android apk to Fabrics without using plugin
body: <p>Is there a way to upload any working apk file to Fabrics?</p>
  <p>I know how this works if you have the plugin and using Android Studio. But i am currently developing with React Native and an there is no plugin for WebStorm.</p>
  <h3>Update</h3>
  <p>Thanks Mike for the fast answer. According to your post i tried to run with the gradle version. It didn´t work running with</p>
  <pre><code>gradle assembleRelease crashlyticsUploadDistributionRelease
  </code></pre>
  <p>but instead it worked when i ran with</p>
  <pre><code>./gradlew assembleRelease crashlyticsUploadDistributionRelease
  </code></pre>
  <p>The problem now is that i am getting some errors which i don´t know how to handle with:</p>
  <pre><code>* What went wrong:
  Execution failed for task ':app:crashlyticsUploadDistributionRelease'.
  &gt; Distribution upload failed.
  
  * Try:
  Run with --debug option to get more log output.
  
  * Exception is:
  org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:crashlyticsUploadDistributionRelease'.
