copied!<p>The error message I get for this is:</p> <pre><code>org.xmlpull.v1.XmlPullParserException: Binary XML file line #18: <item> tag requires a 'drawable' attribute or child tag defining a drawable </code></pre> <p>Doing a little digging, the specs say the <code>background</code> attribute should support either a colour, or reference to a drawable resource:</p> <p>... Looking at the resource you're referencing, it <em>is</em> a <code>StateListDrawable</code>.</p> <pre><code>platforms/android-17/data/res/color/primary_text_dark.xml <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_enabled="false" android:color="@android:color/bright_foreground_dark_disabled"/> <item android:state_window_focused="false" android:color="@android:color/bright_foreground_dark"/> <item android:state_pressed="true" android:color="@android:color/bright_foreground_dark_inverse"/> <item android:state_selected="true" android:color="@android:color/bright_foreground_dark_inverse"/> <item android:state_activated="true" android:color="@android:color/bright_foreground_dark_inverse"/> <item android:color="@android:color/bright_foreground_dark"/>  </selector> </code></pre> <p>However, the docs for StateListDrawable also explicitly say the <code>drawable</code> attribute must be defined for <code>item</code> elements:</p> <pre><code>https://developer.android.com/guide/topics/resources/drawable-resource.html <item> Defines a drawable to use during certain states, as described by its attributes. Must be a child of a <selector> element. attributes: android:drawable Drawable resource. Required. Reference to a drawable resource. </code></pre> <p>... which isn't the case for the case for <code>primary_text_dark.xml</code>. So, it's not working because the drawable you're referencing doesn't seem to conform to the spec.</p> <p>I think the workaround is to reference the colour that's used in <code>primary_text_dark</code> for the default state: <code>bright_foreground_dark</code>. Seeing as that's not public, you need to go directly to the one it references, which is:</p> <pre><code>android:background="@android:color/background_light" </code></pre>
