Facebook Android SDK cannot load applicationId

I have:

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/appid" />

in my ApplicationManifest and:

<?xml version="1.0" encoding="utf-8" ?>
<resources>
  <string name="appid">FROMDEVELOPERDOTFACEBOOK</string>
</resources>

But I keep getting the following warning:

11-25 14:52:27.577 D/Request (10781): Warning: Sessionless Request needs token but missing either application ID or client token.

I am able to load the string fine from resources. Any idea what I may be missing? Thanks
