即使我没有选择photothumb.db作为可绘制对象，我也会得到一个错误提示，说photothumb.db应该以.xml或.png结尾
我的profilesmaller图像的类型为png
下面是我的代码

<FrameLayout 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/profilesmaller"
    tools:context="charlenebuena.guest.HomeFragment">
</FrameLayout>

下面是我的Gradle控制台消息
