我已经创建了一些原有的应用程序的天气predicting，直升机安置救火了西班牙的土壤，最好的办法，根据西班牙法律还清抵押贷款，全部用自己的算法。 现在，我想知道是否有一种方法，我可以发布这是Android应用程序，并从中获利。我不知道有关业务，所以任何帮助将是巨大的。 我读过你必须以发布支付。但是，我想这是得到您的应用程序的用户被称为第一步骤，然后，如果它是成功的，你可以赚到钱。纠正我，如果我错了。 在多种平台上（Linux中原文）上运行我的应用程序，他们可以在英语和西班牙语使用。

I've created several original applications for weather predicting, helicopter placement to fight fires over Spanish soil, best way to pay off a mortgage according to Spanish legislation, all using my own algorithms. Now, I would like to know if there’s a way I can publish this as Android applications and earn money. I have no idea about business so any help would be great. I’ve read you have to pay in order to publish. But, I suppose that’s a first step to get your application to be known by the users and then, if it’s successful you can earn money from. Correct me if I’m mistaken. My applications run on several platforms (written originally in Linux) and they can be used in both English and Spanish.

推荐答案

您需要支付一定的费用，能够发布Android市场上，但是这是25美元的一次性费用，如果我没有记错。赚钱与您的应用程序，我能想到的以下三种可能：

You need to pay a fee to be able to publish on the Android market, but this is a one-time fee of 25 dollars, if I remember correctly. To earn money with your apps I can think of the following three possibilities:

展示广告，您会收到一些钱，当用户点击广告。在我自己的应用程序我使用Admob的，但也许还有其他的广告商。

Display ads in your Apps, you receive some money when your users click on an Ad. In my own apps I use Admob, but maybe there are other ad providers.

在Android市场上你的应用程序设置一个价格。您将收到的钱从谷歌每购买（虽然谷歌采用的是30％）。

Set a price for your app in the Android market. You will receive money from Google for every purchase (although Google takes 30% of that).

使用应用内购买出售订阅您的应用程序。

Use in-app purchases to sell subscriptions to your apps.

有关这些选项可以在Google他们更多的信息，有足够多的文件，以了解。

For more information on these options you can Google them, there is more than enough documentation to find.

修改 正如下面你的问题的意见，这实际上是错误的网站这种类型的问题。我之前已经指出了这一点。

EDIT As seen in the comments below your question, this actually is the wrong site for this type of questions. I should have pointed that out before.
