如何确定正在使用哪个值文件夹

Question

Periodically, I will run in to an issue where a layout file will not read values from any dimensions file. This comes up when you have multiple values folders with different qualifiers, as I am working with now. I am looking for a way to add some logging that will show me exactly which values folder is being used. I have found several examples that allow you to get screen information, such as the following, and am hoping there is some method that will return which values folder / qualifier is being used as well.

int screenDensityDPI = getResources().getConfiguration().densityDpi;
int screenWidth = getResources().getConfiguration().screenWidthDp;
int smallestScreenWidth =getResources().getConfiguration().smallestScreenWidthDp;

If you name your directories as values-small, values-normal, values-large and values-xlarge, you can use:

int screenSize = getResources().getConfiguration().screenLayout &
                            Configuration.SCREENLAYOUT_SIZE_MASK;

switch (screenSize) {
  case Configuration.SCREENLAYOUT_SIZE_SMALL:
      // values-small directory
      break;
  case Configuration.SCREENLAYOUT_SIZE_NORMAL:
      // values-normal directory
      break;
  case Configuration.SCREENLAYOUT_SIZE_LARGE:
      // values-large directory
      break;
  case Configuration.SCREENLAYOUT_SIZE_XLARGE:
      // values-xlarge directory
      break;
}
