Android Market doesn’t allow developers from my country to sell app. From what I understand the only chance to make some profit is to place ads in my application.
Does ads make a decent profit or is there some other way to earn money are there any other payments system available for Android to bypass Google’s limitations?
You can use PayPal in some of the following ways:
According to this article PayPal can already facilitate in-app purchases in some countries. When this will become available outside of the mentioned I don't know.
You can use YAAM, an alternative market, with Paypal paiement. Like the market, there is an application which manages update. For Moblox(our game) customers, it is very easy.
YAAM is an open source product, so you can developp your own Market if you want.
An example that came to mind for the situation you described is how Rovio initially launched Angry Birds on android. Angry Birds for android started by being available only on http://www.getjar.com/ with ad support in game. Eventually they moved into the android market, as well, but the game was free either way in this case, so revenue would be coming through ads on the android side of things.
