为什么App Bundle会导致InflateException？

Question

我已经在Google Play上发布了.aab（Android应用捆绑包）文件。当我在VIVO Android 7.0设备上测试.aab时，它显示InflateException。最后，我通过删除xhdpi / dimens.xml解决了它，有人能告诉我为什么会这样吗？

xhdpi / dimens.xml：

<resources>
    <dimen name="sleeping_activity_image_text_margin_top">32dp</dimen>
</resources>

布局：

...
            <TextView
                android:id="@+id/tip_text"
                android:layout_width="320dp"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:layout_marginLeft="0dp"
                android:layout_marginTop="@dimen/sleeping_activity_image_text_margin_top"
                android:layout_marginRight="0dp"
                android:gravity="center"
                android:paddingLeft="20dp"
                android:paddingRight="20dp"
                android:text="@string/sleeping_tip_text"
                android:textColor="@color/white_transparent_50"
                app:layout_constraintLeft_toLeftOf="parent"
                app:layout_constraintRight_toRightOf="parent"
                app:layout_constraintTop_toBottomOf="@id/tip_image" />
