title: Could not find tools.jar React native Android in Mac OSX
body: <p>I reach this step  :</p>
  
  <pre><code>reactive-native run-android ; 
  </code></pre>
  
  <p>When I run <code>echo $JAVA_HOME</code>, i got the full path to JDK directory : </p>
  
  <pre><code>/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
  </code></pre>
  
  <p>I add that path to <code>./android/gradle.properties</code> : </p>
  
  <pre><code>org.gradle.java.home=/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/
  </code></pre>
  
  <p>I got the same error which is  :</p>
