I have an app that works as intended when run on API 8, but when I run it on any older API version, it crashes with:

What reasons might there be for this failing on API7? My drawable resources are in res/drawable (I’ve tried making copies in /drawable, and the problem persists regardless of drawable-{hdpi,ldpi} folders). For the sake of completeness, needle_green.xml:

<?xml version="1.0" encoding="UTF-8"?>
<rotate         xmlns:android="http://schemas.android.com/apk/res/android"
                android:fromDegrees="90"
                android:toDegrees="90"
                android:pivotY="125"
                android:drawable="@drawable/needle_base_green" />

And needle_base_green:

<?xml version="1.0" encoding="UTF-8"?>
<shape          xmlns:android="http://schemas.android.com/apk/res/android"
                android:shape="line">
    <stroke     android:width="2dp"
                android:color="#00ff00" />
</shape>

This is pretty much a first android app, so it’s likely something shockingly trivial. Thanks for any help.

    Android can’t find res/drawable/needle_green.xml. Do you have it, if no show us the code.

    added:
    Try to use #FFFF0000 (first two is alpha) as color value
