Cannot Locate Strings that Exist

Issue

I have the following error:

From menu:

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:appcompat="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/menu_item_new"
        android:title="@string/menu_item_new"
        appcompat:showAsAction="always"></item>
    <item
        android:id="@+id/menu_item_save"
        android:title="@string/menu_item_save"
        appcompat:showAsAction="always"></item>
    <item
        android:id="@+id/menu_item_delete"
        android:title="@string/menu_item_delete"
        appcompat:showAsAction="always"></item>
    <item
        android:id="@+id/menu_item_rate"
        android:title="@string/menu_item_rate"></item>
    <item
        android:id="@+id/menu_item_website"
        android:title="@string/menu_item_website"></item>
    <item
        android:id="@+id/menu_item_report"
        android:title="@string/menu_item_report"></item>

</menu>

Even though all those strings do in fact exist:

<string name="menu_item_new">New</string>
<string name="menu_item_save">Save</string>
<string name="menu_item_delete">Cancel</string>
<string name="menu_item_rate">Rate on Google Play</string>
<string name="menu_item_website">Website</string>
<string name="menu_item_report">Report a Bug</string>

I have attempted to simply re-write the code as well as clean and rebuild, yet the error persists.

How can this be resolved?

Solution

resources tag is missing from strings.xml file. Android couldn't locate the string resource.

Make following changes:

<resources>
  <string name="menu_item_new">New</string>
  <string name="menu_item_save">Save</string>
  <string name="menu_item_delete">Cancel</string>
  <string name="menu_item_rate">Rate on Google Play</string>
  <string name="menu_item_website">Website</string>
  <string name="menu_item_report">Report a Bug</string>
</resources>
