Android Context and context PowerManager
<p>Im getting errors at <strong>context</strong> and <strong>Context</strong>. What should go there? </p>

<pre><code>    PowerManager mgr =  (PowerManager)context.getSystemService(Context.POWER_SERVICE);
    WakeLock wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
    wakeLock.acquire();
</code></pre>
