android - 由于背景图像，应用程序在 Nexus 4(4.4.4) 上崩溃

Question

我已将背景图像设置为根布局。这适用于 Nexus 5(5.0.1) 和 Nexus 5x(6.0.1)。但在 Nexus 4(4.4.4) 上应用程序崩溃并给出以下错误

这是 xml 文件。

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout 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"
        android:background="@drawable/backgraound">


        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="none">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical">
       // other view
     </LinearLayout>
        </ScrollView>
    </RelativeLayout>

如果我从 xml 中删除背景图像，这也适用于 Nexus 4。我该如何解决这个问题？提前致谢

您可能已将图像放入 drawable-v21 文件夹中，该文件夹引用 Api 级别 21 及以上。这些文件夹特定于 Lolipop 和 post Lolipop 版本。这就是为什么它不能在 Kitkat 或更低版本中工作。将您的图像放入 drawable 文件夹中，以便所有 api 版本都可以访问该文件夹。很高兴提供帮助...
