我在整合谷歌的应用内结算方面遇到了很多麻烦.

我有一个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);

并调用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,所以我何时应该调用finish()来返回主活动.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.

任何帮助都非常感谢.

谢谢,

P.S.：My Old Question,尚未解决…..

解决方法

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正在尝试实现的目标.

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找到错误的结果,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()?");
            }
    }
