Question

我在整合谷歌的应用内结算方面遇到了很多麻烦。

我有一项应该进行应用内结算的活动。我正在使用startActivity方法从我的主要活动中调用此活动。



Intent i = new Intent();
i.setComponent(new ComponentName("com.mypackage.mainactivity","com.mypackage.mainactivity.InAppBillingActivity"));                
startActivity(i);

并致电mBillingService.requestPurchase("android.test.purchased", "10") 在In-App-Billing活动的onCreate方法中。



 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mHandler = new Handler();
        mInAppBillingPurchaseObserver = new InAppBillingPurchaseObserver(mHandler);
        mBillingService = new BillingService();
        mBillingService.setContext(this);

        ResponseHandler.register(mInAppBillingPurchaseObserver);
        boolean supported = mBillingService.checkBillingSupported();
        System.out.println("onCreate.isBillingSupported " + supported);
        if(supported) {
            Log.i("AJ", "Calling requestPurchase");
            mBillingService.requestPurchase("android.test.purchased", "10");
        }
    }

由于In-App-Billing对服务器进行异步调用，我何时应调用finish（）返回主活动。但我不希望活动结束，我仍然需要异步调用的结果。那么我该如何处理呢。

我在向服务器发送请求后调用了finish（）。但后来我得到了这个例外：

它没有退出应用程序，但它停止了InAppBillingActivity。

非常感谢任何帮助。

谢谢， AKASH

P.S。：My Old Question，尚未解决.....

Answer 1

你应该使用startActivityForResult() Context.StartActivityforResult URL

通过这种方式，您可以开始计费，让它执行异步回调，当它收到“成功”或“失败”时，您可以调用finish（）;发回结果。

In App Billing的另一个教程是：Simple InApp Billing，这为您提供了第二个视角，可能会帮助您了解BillingService尝试实现的目标。

修改的

对于'Simple InApp Billin'的错误：您在购买时收到错误，您可以在结算服务中发现错误，否则在结算助手中您可以更新方法以停止此操作：

 protected static void verifyPurchase(String signedData, String signature) {
            ArrayList<VerifiedPurchase> purchases = BillingSecurity.verifyPurchase(signedData, signature);
            if(purchases != null && !purchases.isEmpty()){ // Check for NPE
                    latestPurchase = purchases.get(0);

                    confirmTransaction(new String[]{latestPurchase.notificationId});
            } else {
                    Log.d(TAG, "BillingHelper.verifyPurchase error. purchases was null");
            }

            if(mCompletedHandler != null){
                    mCompletedHandler.sendEmptyMessage(0);
            } else {
                    Log.e(TAG, "verifyPurchase error. Handler not instantiated. Have you called setCompletedHandler()?");
            }
    }

InAppBilling活动和完成（）
