title: No resource found that matches the given name at layout_hint
body: <p>I am new in fact this is my first attempt to android program. I am following the android developers training website. My <code>activity_main.xml</code> looks like following :</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="horizontal"
  android:paddingBottom="@dimen/activity_vertical_margin"
  android:paddingLeft="@dimen/activity_horizontal_margin"
  android:paddingRight="@dimen/activity_horizontal_margin"
  android:paddingTop="@dimen/activity_vertical_margin"
  
  tools:context=".MainActivity" &gt;
  
  &lt;EditText android:id="@+id/edit_message"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" 
      android:layout_hint="@string/edit_message"/&gt;
  </code></pre>
  
  <p>Now it shows an error and warning like:</p>
  
  <p>Warning - <code>This text field does not specify an inputType or a hint</code></p>
  
  <p>Error - <code>error:Error:No resource found that matches the given name( at 'layout_hint' with the value '@string/edit_message')</code></p>
