从第二次“在应用内购买”在Android中抛出异常 [英] From second time "In app purchase" throwing exception in Android
问题描述
我试图加入应用程序购买，我已成功通过显示可用的SKU。现在我想做一个假购买。所以我使用了appId =android.test.purchased。这是第一次完美无缺，但是接下来它会抛出异常，如下所示。
I Am trying to include in app purchase and i have successfully through in showing up SKUs available.Now I want to make a fake purchase.So I used appId = "android.test.purchased". For the first time it worked flawlessly, but from next it is throwing exception as below.
尝试调用虚拟方法'android.content.IntentSender android.app.PendingIntent。空对象引用上的getIntentSender（）'

推荐答案
您可以了解上述问题的解决方案。要解决这个问题，您应该在Android手机上清除Google Play应用的缓存。当我们进行任何应用内购买时，Google会维护详细信息播放服务。一旦购买了产品，播放隔离特定的sku，以避免重复购买。
注 - 这实际上是出于测试目的。因为Google Play服务会维护所有应用程序购买或Oauth或任何其他设施的应用程序的记录。
希望它会帮助那些面临这个问题的人。
Hi get to know about the solution for the prob mentioned above.To get rid of this you should clear the cache of Google play app on your android phone.When we make any in app purchase are details are maintained by the Google play services.So once the a product is purchased play Isolates the particular sku,to avoid duplicate purchase. Note - This is actually for testing purpose. Because Google play services maintains the record of all applications which have in app purchase or Oauth or any other facilities. Hope it would help some one who is facing this problem.
