android - Missing styles. Is the correct theme chosen for this layout?

Question

Missing styles. Is the correct theme chosen for this layout? Use the Theme combo box above the layout to choose a different layout, or fix the theme style references. Failed to find style mapViewStyle in current theme.

I tried every solutions available to solve this problem but nothing seems to work. I have included library in the manifest file. I even created style is styles.xml, I have chosen Google Apis build target as well.

Can somebody please give me a solution?

here is my xml file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
style="@style/AppTheme"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >


 <com.google.android.maps.MapView
     android:id="@+id/themap"
     style="@style/mapViewStyle"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:apiKey="here i have my key"
     android:clickable="true"
     android:enabled="true" />

  </RelativeLayout>   

Here is my manifest snippet:

  <uses-library android:name="com.google.android.maps" />

    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".Second" />

    <activity android:name=".Third"  android:theme="@android:style/Theme.Black"/>
  </application>

here is my style.xml file

<resources>
    <style name="mapViewStyle" parent="@android:style/Theme.Black">
    </style>
</resources>

For Android Studio (or IntelliJ IDEA),

If everything looks OK in your project and you're still receiving the error in your layouts, try to 'Invalidate caches & restart'.

Enjoy a coffee while Android Studio is recreating caches & indexes.
