Color Resource with type #0x1d is not valid for android:colorAccent

Issue

I have the following error when starting an Activity on Android 5 (on a Nexus 5).

By looking at the Resource ID on R I found that the resource is the color I use for my android:colorAccent in:

<style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar">
    <item name="android:colorPrimary">@color/primary</item>
    <item name="android:colorPrimaryDark">@color/primaryDark</item>
    <item name="android:colorBackground">@color/background</item>
    <item name="android:colorAccent">@color/accent</item>
    <item name="android:colorControlHighlight">@color/controlHighlight</item>

    <item name="android:navigationBarColor">?android:colorPrimaryDark</item>
    <item name="android:statusBarColor">?android:colorPrimaryDark</item>

    <item name="android:windowBackground">?android:colorBackground</item>
</style>

The Resource itself is:

<color name="accent">@color/md_deep_orange_500</color>
<color name="md_deep_orange_500">#ff5722</color>

By changing the Color to some other colors (like @color/primaryDark) I get the same error but with the ID of the new color. Am I missing something?

Solution

Try explicitly adding the alpha value i.e.

<color name="md_deep_orange_500">#ffff5722</color>
