InApp购买RESTORE_TRANSACTIONS，我不能推测的code OUT [英] InApp Purchase RESTORE_TRANSACTIONS, I am not able to figure the code out

问题描述

我在我的编码添加在应用程序内购买，它的运作良好，而购买，但给人的错误，当我尝试添加Restore_Transaction code当应用程序被删除并重新安装应用程序关闭，我增加了以下编码

中的onCreate我写

  startService（新意图（mContext，BillingService.class））;
        BillingHelper.setCompletedHandler（mTransactionHandler）;

        如果（BillingHelper.isBillingSupported（））{
            BillingHelper.restoreTransactionInformation（BillingSecurity
                    .generateNonce（））;
        }
 

，然后我用所谓的处理程序

 公开处理程序mTransactionHandler =新的处理程序（）{
        公共无效的handleMessage（android.os.Message味精）{
            如果（BillingHelper.latestPurchase.isPurchased（））{
                showItem（）;
            }
        };
    };

    私人无效showItem（）{
        购买= Purchased.getPurchaseInfo（getApplicationContext（））;
        如果（购买== NULL）{
            日期D =新的日期（）;
            Toast.makeText（getApplicationContext（），--- Upgrated ---，
                    Toast.LENGTH_LONG）.show（）;
            购买=新购（getApplicationContext（））;
            purchased.isPurchased = 1;
            purchased.purchasedDate = d.getTime（）;
            purchased.save（）;
            意向意图=新的意图（ActorGenieActivity.this，
                    SplashScreen.class）;
            startActivity（意向）;
        }
    }
 

解决方案

我找到了答案，我的问题，感谢名单，以anddev

您必须检查采购不为空

 公共静态无效verifyPurchase（字符串签名数据，特征码）{
    ArrayList的＆LT; VerifiedPurchase＆GT;购买= BillingSecurity.verifyPurchase（
            签名数据，签名）;
    如果（购买= NULL和放大器;！＆安培;！purchases.isEmpty（））{
        latestPurchase = purchases.get（0）;
        confirmTransaction（新的String [] {latestPurchase.notificationId}）;
        如果（mCompletedHandler！= NULL）{
            mCompletedHandler.sendEmptyMessage（0）;
        } 其他 {
            登陆
                    .E（
                            标签，
                            verifyPurchase错误处理程序没有实例化你叫setCompletedHandler（）？）;
        }
    }
}
 

和在Confirm_Notificationü甲肝检查

 如果（notifyIds [0]！= NULL）
 

I am adding a in app purchase in my coding, it's working well while purchase but gives error and application closes when I try to add Restore_Transaction code when application is removed and installed again, I have added below coding

in onCreate i wrote

startService(new Intent(mContext, BillingService.class));
        BillingHelper.setCompletedHandler(mTransactionHandler);

        if (BillingHelper.isBillingSupported()) {
            BillingHelper.restoreTransactionInformation(BillingSecurity
                    .generateNonce());
        }

and then i called handler using

public Handler mTransactionHandler = new Handler() {
        public void handleMessage(android.os.Message msg) {
            if (BillingHelper.latestPurchase.isPurchased()) {
                showItem();
            }
        };
    };

    private void showItem() {
        purchased = Purchased.getPurchaseInfo(getApplicationContext());
        if (purchased == null) {
            Date d = new Date();
            Toast.makeText(getApplicationContext(), "--- Upgrated ---",
                    Toast.LENGTH_LONG).show();
            purchased = new Purchased(getApplicationContext());
            purchased.isPurchased = 1;
            purchased.purchasedDate = d.getTime();
            purchased.save();
            Intent intent = new Intent(ActorGenieActivity.this,
                    SplashScreen.class);
            startActivity(intent);
        }
    }

解决方案

I found the answer to my question, thanx to anddev

You have to check for purchases not to be null

public static void verifyPurchase(String signedData, String signature) {
    ArrayList<VerifiedPurchase> purchases = BillingSecurity.verifyPurchase(
            signedData, signature);
    if (purchases != null && !purchases.isEmpty()) {
        latestPurchase = purchases.get(0);
        confirmTransaction(new String[] { latestPurchase.notificationId });
        if (mCompletedHandler != null) {
            mCompletedHandler.sendEmptyMessage(0);
        } else {
            Log
                    .e(
                            TAG,
                            "verifyPurchase error. Handler not instantiated. Have you called setCompletedHandler()?");
        }
    }
}

and in Confirm_Notification u hav to check for

if (notifyIds[0] != null)
