title: Android Manifest Instrumentation
body: <p>I have a <code>android test project</code> setup to test my <code>android project</code>. In the <code>android test project</code>'s manifest, I have an entry for <code>instrumentation</code>. It looks like:</p>
  
  <pre><code>&lt;instrumentation
      android:name="android.test.InstrumentationTestRunner"
      android:targetPackage="com.company.android" /&gt;
  </code></pre>
  
  <p>I'm curious what the point of this entry is, and particuarly what the purpose of <code>android:targetPackage="com.company.android"</code> is for. I ask, because I refactored the old project and put classes into different packages, so I'm curious on what I need to update this value to... is it suppose to point the the package where the class that extends <code>android.app.Application</code> is at?</p>
