// Taken from Contacts List example
public static int calculateMemCacheSize(float percent) {
      if (percent < 0.05f || percent > 0.8f) {
        throw new IllegalArgumentException("setMemCacheSizePercent - percent must be "
                + "between 0.05 and 0.8 (inclusive)");
    }
    return Math.round(percent * Runtime.getRuntime().maxMemory() / 1024);
