title: Android XML Pulse Animation not working as expected
body: <p>I am trying to code an animation that mimics a pulse animation that resembles this:</p>
  
  <p>Concentrate on the <strong>inner</strong> blue circle (ignore the outer dark blue circle)</p>

  <p>Here's what I managed to code so far:</p>
  
  <pre><code>&lt;set xmlns:android="http://schemas.android.com/apk/res/android"
      android:shareInterpolator="false"&gt;
      &lt;scale
          android:duration="2000"
          android:fromXScale="1"
          android:fromYScale="1"
          android:pivotX="50%"
          android:pivotY="50%"
          android:toXScale="0.8"
          android:toYScale="0.8" /&gt;
  
      &lt;scale
          android:duration="2000"
          android:fromXScale="0.8"
          android:fromYScale="0.8"
          android:pivotX="50%"
          android:pivotY="50%"
          android:startOffset="2000"
          android:toXScale="1.8"
          android:toYScale="1.8" /&gt;
  
      &lt;scale
          android:duration="2000"
          android:fromXScale="1.8"
          android:fromYScale="1.8"
          android:pivotX="50%"
          android:pivotY="50%"
          android:startOffset="2000"
          android:toXScale="1"
          android:toYScale="1" /&gt;
  &lt;/set&gt;
  </code></pre>
  
  <p>While this works for a certain extent, the animation skips and stutters when it repeats again. Can someone tweak it a bit to mimic a smooth pulse animation? (grow and reduce)</p>
