在app计费中，getskudetails空点异常？
提问于 2014-10-12 05:11:40
我试图进入应用程序账单3工作，但不知道我做错了什么。我正在学习一个教程，但是我被卡住了。如果有人能帮助我让它工作，我将不胜感激。
我只是想让最简单的静态测试正常工作。我可以在我的手机上得到它，我正确地导入了android.vending.billing和inappbillingservice.aidl。
我在SkuDetails = mservice.getSkuDetails(3, getPackageName(), "inapp", querySkus)拿到了NullPointerException学位。
我可能还有其他错误，但这就是我目前所做的。
public class MainActivity extends ActionBarActivity {

// TODO Auto-generated method stub
mservice = IInAppBillingService.Stub.asInterface(service);
System.out.println("it conncekcted!!!!!!!!");

// TODO Auto-generated method stub
System.out.println("it disconncected!!!!!!!!!!");

我让它起作用了，我知道它远不是最好的例子，但对于这个问题，我找不到一个有效的例子，所以希望这能对某些人有所帮助。我打算放一张源文件的图片，这让我有点困惑，但没有足够的代表来添加一个img。我的例子来自https://www.youtube.com/watch?v=-h2ESH71hAI，感谢他。
