<p>This guide is a quick start to adding a map to an Android app. We are using Android Studio as a development environment.</p>
<p>Get the full code from <strong><a href="https://github.com/arunk7839/GoogleMapExample">Github</a></strong></p>
<p><span style="color: #000080;"><strong>Step 1. Create a Google Maps project</strong></span></p>
<p>Follow these steps to create a new app project including a map activity:</p>
<ol>
<li>Start Android Studio.</li>
<li>Create a new project.</li>
<li>Enter your app name, company domain, and project location, as prompted. Then click <span style="color: #008000;"><strong>Next</strong></span>.</li>
<li>Select the form factors you need for your app or just select <span style="color: #008000;"><strong>Phone and Tablet</strong></span>. Then click <span style="color: #008000;"><strong>Next</strong></span>.</li>
<li>Select <span style="color: #008000;"><strong>Google Maps Activity</strong></span> in the &#8216;Add an activity to Mobile&#8217; dialog. Then click <span style="color: #008000;"><strong>Next</strong></span>.</li>
<li>Enter the activity name, layout name and title. Then click <span style="color: #008000;"><strong>Finish</strong></span>.</li>
</ol>
<p> ;</p>
<p><span style="color: #000080;"><strong>Step 2.Get a Google Maps API key</strong></span></p>
<p style="text-align: left;"> For getting the map api key go to <strong><a href="https://console.developers.google.com/?_ga=2.188092840.1254419158.1526730950-593994706.1525417017">Google API Console.</a></strong> or watch the video how to create the Map API key:</p>

 sign the APK for publishing.
 You can define the keys for the debug and release targets in src/debug/ and src/release/.
