So, I jumped through all the hoops to start charging for my apps, but whilst writing up the draft info for my soon-to-release app I noticed that out of all the countries I’m able to distribute to, only a handful of them have the ability to set individual prices. All of the other countries not only don’t give you that option, but they don’t show any currency conversion for it.
Does Google charge them the default currency (in my case, $0.99 USD), or do they do day-of-purchase currency conversions of their country, or do they just distribute them for free?
You can set the price specifically for that country if (and only if) you’ve targeted that particular country for selling your app. You can either set the price manually, or use Auto-Fill to set a price in each of the targeted countries based on the exchange rate and your home currency price.

If you don’t have the ability to target that specific country, it might be that it’s not currently possible to sell apps there via Google Play.
