title: How can I upgrade react-native gradle version
body: <p>I need help.
  I can't upgrade gradle version of my react-native project.</p>
  
  <p>I try a lot of things, downloaded last version of Android Studio &amp; SDK Tools etc.</p>
  
  <p>I changed this file \android\gradle\wrapper\gradle-wrapper.properties, I tried to upgrade using <code>npm install -g react-native-git-upgrade</code> but still I can't upgrade it.</p>
  
  <p>When I react-native eject It's exports 
  "<strong>distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip</strong>"</p>
  
  <p>Waiting for answers.</p>
