Resources$NotFoundException in Graphical Layout ADT preview (but app actually Works)

Question

My problem is that loading an array of strings defined in XML works in the app but will result in an error in the ADT Graphical Layout preview.

Now I can\'t see any

I found a kind of a workaround whereby you have to hijack android's own attributes to get access to resources in the designer.

The following should provide the idea, but you would have to find a native android property of type int[]

This custom view XML should render in the graphical layout preview while using resources

styles.xml - Style specifying some of the resources to use

attrs.xml - Custom attribute definition compatible with design-time preview

ShowcaseView.java - Using the custom attributes in the custom view

public ShowcaseView(Context context) {
    this(context, null, R.styleable.CustomTheme_showcaseViewStyle);
}

public ShowcaseView(Context context, AttributeSet attrs) {
    this(context, attrs, R.styleable.CustomTheme_showcaseViewStyle);
}

public ShowcaseView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    // Get the attributes for the ShowcaseView
    final TypedArray styled = context.getTheme().obtainStyledAttributes(attrs, R.styleable.ShowcaseView, 0, 0);
    showcase = styled.getDrawable(R.styleable.ShowcaseView_android_src);
    titleText = styled.getString(R.styleable.ShowcaseView_android_contentDescription);
    subText = styled.getString(R.styleable.ShowcaseView_android_description);
    buttonText = styled.getString(R.styleable.ShowcaseView_android_text);
    backColor = styled.getInt(R.styleable.ShowcaseView_sv_backgroundColor, Color.argb(128, 80, 80, 80));
    detailTextColor = styled.getColor(R.styleable.ShowcaseView_sv_detailTextColor, Color.WHITE);
    titleTextColor = styled.getColor(R.styleable.ShowcaseView_sv_titleTextColor, Color.parseColor("#49C0EC"));
    styled.recycle();
    // Now make use of the fields / do further initialization ..
}
