0.99.我已经设置了Google商人帐户，但尚未将其链接到我的银行帐户.现在，可以立即更改价格，因为我找不到该选项，或者我首先必须链接到银行帐户，然后该选项才会显示.

0.99. I have setup the Google merchant account but have not yet linked it to my bank account. Now, is it possible to change the price right now, because I do not find the option, or do I first have to link to a bank account and then the option will show up.

如果您以前曾在Android Marketplace上免费发布过一个应用程序，则无法将其设为付费应用程序，而无需发布它是完全不同的应用程序.

您可以更改付费应用程序的价格并免费提供以前付费的应用程序，但不能使以前免费的应用程序付费.

If you have previously released an application as free on the Android Marketplace you cannot then make it a paid app without releasing is as an entirely different application.

You are able to change the price of a paid application and make a previously paid application free but you cannot make a previously free application paid.
