问题描述
我使用的应用内计费，从谷歌对于Android的第一次。但是，如果用户没有连接到互联网或没有安装谷歌框架（例如，使用自定义光盘），可能其他场合（如错误/老市场版等）这种方法（提供IabHelper类中）：
I am using in-app billing from Google for Android for the first time. However, if a user doesn't have an internet connection or no google framework installed (e.g. with custom roms) and probably other occasions (like wrong/old market version etc.)This method (inside the provided IabHelper class):
mContext.bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"),
mServiceConn, Context.BIND_AUTO_CREATE);
不工作，没有服务获取的建立。从活动管理器的小调试信息：
Doesn't work and no service get's established. With a small debugging information from "Activity Manager":
12-17 19:58:31.184: W/ActivityManager(76): Unable to start service Intent { act=com.android.vending.billing.InAppBillingService.BIND }: not found
有没有人找到任何方式来捕获以有意义的方式出错，或任何解决方法，以检查是否意图/包可用？
Has anyone found any way to "catch" this error in a meaningful way, or any workaround to check if the Intent/Package is available?
在此先感谢。
推荐答案
哎呀，发现后不久，回答自己：
argh, found answer myself shortly after:
您必须检查是否意图接收器可通过实施喜欢这里提出了一个方法：[我可以用这个目的 - 博文] [1]
You have to check if the intent receiver is available by implementing a method like suggested here:[can i use this intent - blogpost][1]
（编辑）不过，这种方法需要一些严重的修改适用于该计费服务，为原来的方法仅适用于默认的意图检查，这不是我们想要的。
(edit) However, this method needs some serious changes to be applicable for the billing-service, as the original method only checks for default intents, which is not what we want.
不过，我的实现如下所示，似乎工作，至少在这些设备，规格等我测试：（只测试了用于在应用程序内结算V3）
however, my implementation looks like the following and seems to work, at least on those devices, specifications etc. i tested: (ONLY TESTED FOR V3 OF IN APP BILLING)
public static boolean isBillingAvailable(Context context) {
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
List<ResolveInfo> list = packageManager.queryIntentServices(intent, 0);
return list.size() > 0;
}
这篇关于在应用程序内结算V3，bindService（）目的无法找到的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
