问题描述
假设我有购买在Android Market的游戏;有没有可能让买家的邀请数量有限或codeS发给他们的朋友，这将使他们（朋友）免费下载游戏？
Suppose I have a game for purchase on Android Market; is it possible to allow the buyer to send a limited amount of invites or codes to their friends, which will allow them (the friends) to download the game free of charge?
还是让游戏免费，用我最好的选择，应用内购买和/或codeS的帐户创建（这是一个基于网络的游戏）？
Or is my best bet to make the game free and use in-app purchases and/or codes for account creation (it's a network-based game)?
推荐答案
不幸的是有没有办法让用户安装的情况下，它利用切谷歌退出免费（presumably付费应用，从而致使他们失去了30 ％）
Unfortunately there's not way to let a user install a paid app for free (presumably in case it's exploited to cut Google out, thus costing them their 30%)
您第二个方案 - 一个免费的应用程序与应用程序内购买 - 是目前较好的选择。
Your second option - a free app with in-app purchases - is by far the better option.
