title: hardcoded string “Button”, should use @string resource
body: <p>I am new in Android app development and using Java language. 
  My problem is every time I make a TextView or Button there is a triangle with the exclamation mark below them.
  and when I click it I saw a message saying:</p>
  
  <blockquote>
    <p>hardcoded string “Button”, should use @string resource</p>
  </blockquote>
  
  <p>I have two activities, in my main activity there is a Button that when you click it you will go in second activity.
  But when I go to my <code>main.java</code> to make a code for the button. There's always the above shown error. I think the eclipse can't find the id of my button and same for my TextView they have same error message. </p>
  
  <p>Here is the code I made:</p>
  
  <pre><code>Button b = FindViewById(R.id.button1);
  </code></pre>
  
  <p>I also add:</p>
  
  <pre><code>Button b = (Button) FindViewById(R.id.button1);
  </code></pre>
  
  <p>I am using the latest eclipse classic and ADT august issue. The platform is Android 4.1 API 16.</p>
