    Couldn't resolve resource
    @string/add_new_todo_item_string</p>
  </blockquote>
  
  <p>I'm trying to use a string resource in a Textview. These are my XML files.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/footerView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:gravity="center_horizontal"
      android:text="@string/add_new_todo_item_string"
      android:textSize="24sp" &gt;
  
  &lt;/TextView&gt;
  </code></pre>
  
  <p>XML file for string resources:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
      &lt;string name="app_name"&gt;UILabs&lt;/string&gt;
      &lt;string name="done_string"&gt;Done:&lt;/string&gt;
      &lt;string name="priority_string"&gt;Priority:&lt;/string&gt;
      &lt;string name="date_string"&gt;Date:&lt;/string&gt;
      &lt;string name="add_new_todo_item_string"&gt;Add New ToDo Item&lt;/string&gt;
      &lt;string name="title_string"&gt;Title&lt;/string&gt;
      &lt;string name="status_string"&gt;Status&lt;/string&gt;
      &lt;string name="not_done_string"&gt;Not Done&lt;/string&gt;
      &lt;string name="priority_low_string"&gt;Low&lt;/string&gt;
      &lt;string name="priority_medium_string"&gt;Medium&lt;/string&gt;
      &lt;string name="priority_high_string"&gt;High&lt;/string&gt;
      &lt;string name="time_and_date_string"&gt;Time and Date&lt;/string&gt;
      &lt;string name="no_date_set_string"&gt;0000&amp;#8211;00&amp;#8211;00&lt;/string&gt;
      &lt;string name="no_time_set_string"&gt;00:00:00&lt;/string&gt;
      &lt;string name="choose_date_string"&gt;Choose Date&lt;/string&gt;
      &lt;string name="choose_time_string"&gt;Choose Time&lt;/string&gt;
      &lt;string name="cancel_string"&gt;Cancel&lt;/string&gt;
      &lt;string name="reset_string"&gt;Reset&lt;/string&gt;
      &lt;string name="submit_string"&gt;Submit&lt;/string&gt;
      &lt;string name="enter_title_string"&gt;Enter Title&lt;/string&gt;
  
  &lt;/resources&gt;

  <p>What I'm missing? Thanks for your help.</p>
  
  <p>EDIT: 
  I also have a problem with mi AndroidMAnifest.xml file </p>
  
  <blockquote>
    <p>Cannot resolve symbol '@string/app_name' less... (Ctrl+F1)  Validates
    resource references inside Android XML files.</p>
  </blockquote>
  
  <p>This is my androidManifest file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="course.labs.todomanager"
      android:versionCode="1"
      android:versionName="1.0" &gt;
  
      &lt;uses-sdk
          android:minSdkVersion="14"
          android:targetSdkVersion="19" /&gt;
  
      &lt;application
          android:allowBackup="true"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name" &gt;
          &lt;activity
              android:name=".ToDoManagerActivity"
              android:label="@string/app_name" &gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="android.intent.action.MAIN" /&gt;
  
                  &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
          &lt;activity android:name=".AddToDoActivity" &gt;
          &lt;/activity&gt;
      &lt;/application&gt;
  
  &lt;/manifest&gt;
  </code></pre>
  
  <p>And the error is in the following lines</p>
  
  <pre><code>android:icon="@drawable/ic_launcher"
  android:label="@string/app_name" 
  android:label="@string/app_name" &gt;
  </code></pre>
