Виджеты Material Design не считывают атрибуты стиля

Я пытаюсь создать приложение с Material Design. Следуя официальному документу, я добавил файл style.xml в папку values-v21.

<resources>
    <style name="AppTheme" parent="android:Theme.Material">
        <item name="android:colorPrimary">@color/primary</item>
        <item name="android:colorPrimaryDark">@color/primary_dark</item>
        <item name="android:colorAccent">@color/accent</item>
        <item name="android:textColorPrimary">@color/text_primary</item>
    </style>
</resources>

Проблемы возникают, когда я расширяю макет одним из виджетов из библиотеки поддержки дизайна.

<android.support.design.widget.CoordinatorLayout
    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"
    tools:context=".ui.intro.LoginFragment">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <EditText
            android:id="@+id/etEmail_loginFragment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/Email"
            android:inputType="textEmailAddress"
            android:textSize="@dimen/text_normal"/>

    </android.support.design.widget.TextInputLayout>

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <EditText
            android:id="@+id/etPassword_loginFragment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/Password"
            android:inputType="textPassword"
            android:textSize="@dimen/text_normal"/>

    </android.support.design.widget.TextInputLayout>

    <Button
        android:id="@+id/btnLogin_loginFragment"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/Login"
        android:textColor="@color/text_primary"
        android:textSize="@dimen/text_normal"/>

    <com.google.android.gms.common.SignInButton
        android:id="@+id/btnGoogleSignIn_loginFragment"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"/>

</LinearLayout>


<ProgressBar
    android:id="@+id/progress_loginFragment"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:indeterminate="true"
    android:visibility="gone"/>

</android.support.design.widget.CoordinatorLayout>

Предварительный просмотр макета в Android Studio говорит:

Не удалось преобразовать ?attr/colorPrimaryDark в рисуемый объект (3 похожие ошибки не показаны)

3 ошибки связаны с CoordinatorLayout и двумя TextInputLayout. Если я запускаю приложение, когда я раздуваю макет во фрагмент, я получаю следующее:
