Clone and run react native projects from GitHub
<p>I am trying to build and run react native application in my phone. I tried with <a href="https://facebook.github.io/react-native/docs/getting-started.html" rel="noreferrer">Getting Started</a> and it's working fine. I do the following to run </p>

<ol>
<li><code>cd AwesomeProject</code></li>
<li><code>react-native start</code></li>
<li>Open a new tab in terminal</li>
<li><p><code>curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"</code></p></li>
<li><p><code>react-native run-android</code></p></li>
</ol>

<p>and it runs in my android phone. </p>

<p>Now I am trying to run a <a href="https://github.com/h87kg/NavigatorDemo" rel="noreferrer">project from GitHub</a>, I did the following</p>

<ol>
<li><code>git clone https://github.com/h87kg/NavigatorDemo.git</code></li>
<li><code>cd NavigatorDemo</code></li>
<li><code>react-native start</code></li>
</ol>

<p>I get <code>Command 'start' unrecognized. Did you mean to run this inside a react-native project?</code> error. What should I do to run this project ? Any help is appreciated. Thanks in advance.</p>

<p><strong>Update</strong></p>

<p>After installing dependencies <code>npm install</code> I am able to run the server.
Now when I try to run <code>react-native run-android</code> I get the following error</p>

<pre><code>JS server already running.
Building and installing the app on the device (cd android &amp;&amp; ./gradlew installDebug)...
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
Could not install the app on the device, see the error above.
