Android trying to read image in res/drawable-nodpi-v4/ but that directory doesn't exist in my project

Question

Crashlytics is telling me that my app is crashing when it tries to inflate a particular layout because it can't find the image_uparrow.xml image in the res/drawable-nodpi-v4/.

But I don't have a res/drawable-nodpi-v4/ directory. The only version of image_uparrow.xml in my entire project is in res/drawable-nodpi/ without the -v4.

That image_uparrow.xml is a selector that (oddly) has only one entry in it (must have been an old refactoring artifact or something).

<?xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">
     <item android:drawable="@drawable/uparrow" /> <!-- default -->
 </selector>

And @drawable/uparrow has two possibilities:

• res/drawable-mdpi/uparrow.png
• res/drawable-hdpi/uparrow.png

---

So, beyond the weirdness of having only one item in the selector, why on earth would the system try to open a file in res/drawable-nodpi-v4 when I don't even have that directory in my project at all?

Here's the crash stacktrace:

The part of the layout xml that is having the problem is:

<ImageButton
    android:id="@+id/upButton"
    style="@style/Cashflow.ReorderButton.Up"
    android:layout_alignParentStart="true"
    android:contentDescription="@string/move_row_up" />

Here's the referenced style, which is where the image is defined:

<style name="Cashflow.ReorderButton.Up">
    <item name="android:src">@drawable/image_uparrow</item>
</style>
