我正在尝试使用应用内计费将免费应用程序升级到“付费”版本。我使用的代码来自本教程作为官方开发者处理计费
对于像我这样的简单流程来说,网站过于复杂和混乱。
我的升级代码工作正常。
当我尝试添加一些内容来检查用户是否已经购买但通过重新安装或清除数据(我不在乎是哪一种)丢失了购买数据时,问题就出现了。
在应用程序启动时,我检查第一次运行后设置的标志。如果该标志不存在,则会向用户显示一个对话框,警告他们应用程序将检查以前的购买情况,当他们单击“确定”时,将调用 RestoreTransactionInformation 方法。这会导致应用程序强制关闭。
由于应用程序内计费在调试时或在模拟器上不起作用,因此每次我想尝试代码时都必须发布应用程序的签名版本。当我尝试发出restoreTransactionInformation 请求时,我无法知道应用程序为何退出。有谁知道我如何诊断它,或者什么可能导致我的应用程序死机?或者如何使用restoreTransactionInformation方法的工作示例?
编辑:所以看起来 RESTORE_TRANSACTIONS 请求得到了正确的响应,并返回了我的测试购买的详细信息。不幸的是,在它可以对其进行任何操作之前,该应用程序已被强制关闭。以下是市场响应 RESTORE_TRANSACTIONS 请求后立即发生的情况的 logcat(没有混淆代码):
