title: Android Studio cant find a resource with a given name
body: <p>I am making my first app using Android Studios tutorial and I keep on having this error every time I try to make it. The error is No resource found that matches the given name (at 'hint' with value '@string/edit_message'). This is my code. In one xml file. </p>
  
  <pre><code>&lt;    ?xml version="1.0" encoding="utf-8"?   &gt;
  
  &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"  &gt;
  
      &lt;   EditText android:id="@+id/edit_message"
  
          android:layout_weight="1"
  
          android:layout_width="0dp"
  
          android:layout_height="wrap_content"
  
          android:hint=**"@string/edit_message" /&gt;**
  
      &lt;  Button
          android:layout_width="wrap_content"
  
          android:layout_height="wrap_content"
  
          android:text=**"@string/button_send"** /&gt;
  
  &lt; /LinearLayout&gt;
  </code></pre>
  
  <p>Then in another xml file i have this.</p>
  
  <pre><code>&lt;  ?xml version="1.0" encoding="utf-8"?&gt;
  
  &lt;  resources&gt;
  
      &lt; string name="app_name"&gt;My first app second try&lt;/string&gt;
  
      &lt; string name="hello_world"&gt;Hello world!&lt;/string&gt;
  
      &lt; string name="action_settings"&gt;Settings&lt;/string&gt;
  
  
      &lt; resources&gt;
          &lt; string name="app_name"&gt;My First App&lt;/string&gt;
  
          &lt; string name=**"edit_message"&gt;Enter a message&lt;/string&gt;**
  
          &lt; string name=**"button_send"&gt;Send&lt;/string&gt;**
  
          &lt; string name="action_settings"&gt;Settings&lt;/string&gt;
  
          &lt; string name="title_activity_main"&gt;MainActivity&lt;/string&gt;
  
      &lt;/resources&gt;
  
  &lt;/resources&gt;
  </code></pre>
