This was just an example that fit the example you provided. I trimmed
down the array to only one .png file which I verified time and again
was under the drawable directory and reworked the layout of the file
to match the example. The entire arrays.xml file which is found under
the values directory looks like this:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
<array name="preloaded_drawables">
<item>@drawable/aggies</item>
</array>
</resources>
The same thing happens at the same line.
I get a warning first:
ResourceType Invalid package identifier when getting bag for
resource number 0x7f050000
Then an exception:
Failure preloading resources
android.content.res.Resources$NotFoundException: Array resource ID
#0x7f050000
at android.content.res.Resources.obtainTypedArray(Resources.java:
424)
The code is IDENTICAL. I copied and pasted it except for the preload
that I had to comment out.
