Toast message only in Testing
<p>I am android newbie.</p>

<p>I made a simple program, and I used <code>Toast</code> code for checking if variable is correct or not. After finishing test, I have to remove all the <code>Toast</code> code to release app. I think there must be more effective and better way to do this.  </p>

<p>please help me </p>

<p>thank you in advance.</p>
