android/java getIdentifier with

I'm having trouble getting getIdentifier to work with a class variable. It's strange, because this works:

public Drawable getStationIcon(Context context) {
    int resId = context.getResources().getIdentifier("m1m2_16", "drawable", "com.mypackage.namehere");
    Drawable drawable = context.getResources().getDrawable(resId);
    return drawable;
}

But this doesn't:

public Drawable getStationIcon(Context context) {
    int resId = context.getResources().getIdentifier(this.stationIcon, "drawable", "com.mypackage.namehere");
    Drawable drawable = context.getResources().getDrawable(resId);
    return drawable;
}

And nor does this:

public Drawable getStationIcon(Context context) {
    String stationI = this.stationIcon;
    int resId = context.getResources().getIdentifier(stationI, "drawable", "com.mypackage.namehere");
    Drawable drawable = context.getResources().getDrawable(resId);
    return drawable;
}

And this.stationIcon definitely equals m1m2_16. I've tried other alternatives, ie using ""+this.stationIcon, but nothing works when the first parameter is a variable. Is there something I'm missing?

Strangely it will probably work:

getIdentifier("com.mypackage.namehere:drawable/" + this.stationIcon, null, null);

Resources.getIdentifier() has unexpected behavior when name is numeric
