title: In Android app setting current Thread priority to less than 1 causes a force close
body: <p>I am trying to increase the priority of a thread in my application by putting:</p>
  
  <pre><code>Thread.currentThread().setPriority(N);
  </code></pre>
  
  <p>The normal priority of current thread is 5, I can change <code>N</code> to as low as 1, but if I put it to 0 or -1 I get a force close message on my phone.</p>
  
  <p>Is there a reason I cannot increase the priority of this thread?</p>
