        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme2" parent="android:Theme.Material">
        <item name="android:colorPrimary">@android:color/holo_orange_light</item>
        <item name="android:colorPrimaryDark">@android:color/holo_orange_dark</item>
        <item name="android:textColorPrimary">@android:color/holo_blue_bright</item>
        <item name="android:windowBackground">@android:color/darker_gray</item>

    package="com.blogspot.android_er.androidmultiwindow">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme2">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
