title: How to change the vibration strength in Android?
body: <p>I want to create an app where you can test the <strong>vibration</strong>, including the <strong>strength</strong> and in the normal code you can only set the length of the vibration in milliseconds.
  The problem is I can't find any code that can influence the strength of the vibration motor.</p>
  <p>I have tried:</p>
  <pre><code>Vibrator v = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
  v.vibrate(1000);
  </code></pre>
  <p>It works but as I said, only the milliseconds are adjustable.</p>
