Is there any reason in preloading drawables form resources
<p>Does android maintain in memory chache of application drawable resources and reuses them or it is a good practice to preload all drawables that may be assigned dynamicaly to different widgets like?</p>

<pre><code>public static final int[] SETS = { R.drawable.set0, R.drawable.set1, R.drawable.set2,
        R.drawable.set3, R.drawable.set4, R.drawable.set5, R.drawable.set6,
        R.drawable.set7, R.drawable.set8, R.drawable.set9, R.drawable.set10};
public Drawable[] sets;
void init(){
load(sets, SETS);
}


public void load(Drawable[] d, int[] ids) {
    for (int i = 0; i &lt; ids.length; i++) {
        if (ids[i] == 0)
            d[i] = null;
        else
            d[i] = context.getResources().getDrawable(ids[i]);
    }
}
</code></pre>
