如何在Android 4.1和4.2上调试应用内结算？

Question

我是Android开发人员的新手，我遇到了一个非常烦人且熟悉的问题。

简短版本 ：如何在不购买物理设备的情况下测试我的应用程序？ 具体来说，我正在尝试在4.1和4.2运行的设备上进行测试。 我不能使用模拟器，因为这涉及应用内结算。

长版 ：

今天，我收到了用户的崩溃报告（Android版本= 4.2，设备= A1-811（芒果））。

问题是： 未设置IAB帮助程序。 无法执行操作：queryInventory 。 我在4.3、5.0、5.1上测试了该应用程序，这很好。

我知道发生了实际的崩溃，因为我在mhelper.startSetup（）中检查（！result.isSuccess（））时没有退出。

我的问题是，如何解决未设置IabHelper的根本问题？ 我无权使用Android 4.2设备...

上面评论的答案

最好先捕获错误并修补自己的代码。 尝试重现为什么未设置IAB的确切问题可能是不可能的，因为用户可以在其设备上进行各种修改（可能是特定版本的发行版用户正在运行的错误，这几乎是找不到的，或者类似）。 如您所建议，使用Analytics（分析）找出有多少用户遇到此问题是个好方法。

要回答原始问题，您可以在开发者控制台中创建Alpha或Beta版本，并将具有特定Android版本的用户邀请到测试组中。 这是您可以直接从Dev测试问题和崩溃的方法。 即使不直接成为设备所有者，也要进行控制台。
