what is difference between compileSdkVersion 'Google Inc.:Google APIs:23' and compileSdkVersion 23
<p>Inside the Gradle.build file I see some projects using</p>

<pre><code>compileSdkVersion="'Google Inc.:Google APIs:23"
</code></pre>

<p>and some are just using the number</p>

<pre><code>compileSdkVersion="23"
</code></pre>

<p>What is the difference between the two?</p>
