Google 今天正式推出 In-App Purchase.
Today, we’re pleased to announce the launch of Android Market In-app Billing to developers and users. As an Android developer, you will now be able to publish apps that use In-app Billing and your users can make purchases from within your apps.
有部份 Apps 已經配置了 In-App Purchase，包括 Tap Tap Revenge, Gun Bros, Deer Hunter Challenge HD, Dungeon Defenders 等。
就像 Market 買 App 一樣
In-App Purchase 操作十分簡單，就在程式內按相關按鍵，就會出現如 Market 那樣的購買畫，跟著用信用咭付款便可。隨即會返回程式內繼續，十分方便！
