<li>
<p>Open your <code>Android Main Activity</code> and implement this interface.</p>
</li>
<li>
<p>In <code>Main.java</code> of your Application, add the following:</p>
<div class="literalblock">
<div class="content">
<pre> JmeToHarness harness;
 public JmeToHarness getHarness() {
   return this.harness;
 }
 public void setHarnessListener(JmeToHarness harness) {
    this.harness = harness;
 }</pre>
</div>
</div>
</li>
<li>
<p>Add the following snippet to the onCreate method of your Android Main Activity:</p>
<div class="literalblock">
<div class="content">
<pre>if (app != null)
    ((Main)app).setHarnessListener(this);</pre>
</div>
</div>
</li>
<li>
<p>Add error handling if you want it.</p>
</li>
</ol>

<div class="paragraph">
<p>This bit is ultra useful for calling AdMob changes and Play Games methods (like updating achievements, leader boards, etc, etc)</p>
</div>
<div class="paragraph">
<p>EDIT: Keep this as generic as you possibly can as it should plug &amp; play with iOS &amp; Applets if you keep that in mind. Google Play Services/Play Games Services works for all of the above.</p>

<div class="olist arabic">
<ol class="arabic">
<li>
<p>Open the project properties of your Application</p>
</li>
<li>
<p>Navigate to <code><span class="menuseq"><b class="menu">Application</b>&#160;<i class="fa fa-angle-right caret"></i> <b class="menuitem">Android</b></span></code> and edit the package name.</p>

<p>This does absolutely nothing, but help with consistency.</p>
</div>
<div class="paragraph">
<p>So, to actually change the package name, you will want to:</p>
</div>
<div class="olist arabic">
<ol class="arabic">
<li>
<p>Open the <code>Android Manifest</code></p>
</li>
<li>
<p>Edit the manifest tag key pair: <code>package="&lt;THE NEW PACKAGE NAME&gt;"</code></p>
</li>
<li>
<p>In <code>File view</code>, navigate to nbproject and open the <code>project.properties</code> file.</p>
</li>
<li>
<p>Edit the value of <code>mobile.android.package</code>.</p>
</li>
</ol>
</div>
<div class="paragraph">
<p>Take a moment or 4 to navigate through the directory structure in file view and remove any artifacts left from the previous package name build. Alternately, you can run <code>Clean</code> on the project prior to updating the package name.</p>
