使用矢量的 ShapeableImageView 未找到资源异常？

Question

我在 XML 中使用 ShapeableImageView 作为

 <com.google.android.material.imageview.ShapeableImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_unread_msg"
        />

当我在 OS 5 和 6

上运行应用程序时，我收到资源未找到异常

这是我的矢量图

<vector xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:aapt="http://schemas.android.com/aapt"
android:width="14dp"
android:height="14dp"
android:viewportWidth="14"
android:viewportHeight="14">
<path android:pathData="M7,0L7,0A7,7 0,0 1,14 7L14,7A7,7 0,0 1,7 14L7,14A7,7 0,0 1,0 7L0,7A7,7 0,0 1,7 0z">
    <aapt:attr name="android:fillColor">
        <gradient
            android:endX="7"
            android:endY="14"
            android:startX="7"
            android:startY="0"
            android:type="linear">
            <item
                android:color="#FF63D8FF"
                android:offset="0" />
            <item
                android:color="#FF6397FF"
                android:offset="1" />
        </gradient>
    </aapt:attr>
</path>
</vector>

无法弄清楚为什么会发生崩溃？

用 app:srcCompat 替换 android:src 有效
