I'll build a Xamarin application but when I start the build for the Android project, The compiler gives me 9 errors:

> 
> **9 errors:** No resource found that matches the given names: 
> 
> 
> 1. `attr windowNoTitle`
> 2. `attr colorPrimaryDark`
> 3. `attr windowActionBar`
> 4. `attr windowActionModeOverlay`
> 5. `attr colorAccent`
> 6. `attr colorPrimary`
> 7. `attr colorAccent`
> 8. `Theme.AppCompat.Light.Dialog`
> 9. `Theme.AppCompat.Light.DarkActionBar`
> 
> 
> 

**Notes:** The Errors happens in the file `styles.xml` in the `Project.Droid` project.

Here you can find the `styles.xml` file:

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

  <style name="MainTheme" parent="MainTheme.Base">
  </style>

  <style name="MainTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">#2196F3</item>
    <item name="colorPrimaryDark">#1976D2</item>
    <item name="colorAccent">#FF4081</item>
    <item name="windowActionModeOverlay">true</item>
    <item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item>
  </style>

  <style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">#FF4081</item>
  </style>

</resources>

```

I've nothing changed in the `SmartBox.Droid` project but got this errors. Could the problem happen because I've added a `MainPage.xaml` and a `Map.xaml` in the `SmartBox (Portable)` project? I need two pages because I'll navigate between the two pages.

I've searched everywhere on Google and SO but found no solution that helps me. My source code you could find on GitHub (<https://github.com/HeinPauwelyn/SmartBox>) in the folder Execution → SmartBox
