android 4.2.2中找不到资源异常

Question

我在style.xml文件上为启动画面创建了一个主题。

<style name="SplashTheme" parent="Theme.AppCompat.Light.NoActionBar">
   <item name="android:windowBackground">@drawable/splash_background_96dp</item>
</style>

splash_background_96dp是一个xml drawable。

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/colorWhite"/>

    <item android:gravity="center">
        <bitmap
            android:gravity="fill_horizontal|fill_vertical"
            android:src="@drawable/logo1"/>
    </item>
</layer-list>

logo1是一个png文件。

我在我的应用程序中使用此主题进行启动画面活动。它适用于android 7.1.0但在android 4.2.2上会发生以下异常：
