Android的应用内结算和Proguard的（未知来源） [英] Android In-app Billing and Proguard (Unknown Source)

问题描述

我使用谷歌和的Proguard的应用内结算服务。我使用作为一个Proguard的配置文件是在......一曲/ SDK /工具/ proguard的/ proguard的-android.txt

I am using the In-app Billing service of Google and Proguard. The configuration file that I am using as a Proguard is the one in .../sdk/tools/proguard/proguard-android.txt

由于谷歌说，在这里： http://developer.android.com/google /play/billing/billing_best_practices.html 我添加了配置文件中的以下行：

As Google says here: http://developer.android.com/google/play/billing/billing_best_practices.html I added the following line in the configuration file:

-keep class com.android.vending.billing.**

我使用IAB的从谷歌更新的文件，以及：<一href=\"https://$c$c.google.com/p/marketbilling/source/detail?r=7ec85a9b619fc5f85023bc8125e7e6b1ab4dd69f\" rel=\"nofollow\">https://$c$c.google.com/p/marketbilling/source/detail?r=7ec85a9b619fc5f85023bc8125e7e6b1ab4dd69f

问题是，有时，用户报告随机崩溃这个堆栈跟踪：

The problem is that sometimes, users report random crashes with this stacktrace:

E/AndroidRuntime: FATAL EXCEPTION: Thread-455
java.lang.NullPointerException
    at com.xx.xxxx.util.IabHelper.startSetup(Unknown Source)
    at com.xx.xxxx.util.IabHelper$2.run(Unknown Source)
    at java.lang.Thread.run(Thread.java:856)

这也发生在我的设备（刚刚开放的应用程序），但只有今天我发生过一次。

It also happened in my device (just opening the app) but only happened once to me today.

和我不知道这是否是谷歌文件（IAB）的什么问题，缺少Proguard的配置文件中的

And I am not sure if it is problems of Google files (of IAB) or something is missing in the Proguard configuration file.

推荐答案

添加以下字符串

-keep class com.android.vending.billing.**

要ProGuard的配置告诉他不要混淆了包。

to ProGuard configuration tells him to not to obfuscate that package.

异常来自com.xx.xxxx.util.IabHelper，所以你可以尝试添加像

Exception comes from com.xx.xxxx.util.IabHelper, so you can try to add something like

-keep class com.xx.xxxx.util.IabHelper.**

要保持你的包，因为它是没有ProGuard的。

to keep your package as it was without ProGuard.
