android还原事务在退出后继续关闭应用程序

我根据地下城示例使用代码。除了一件事，一切都很好。问题是恢复事务。当我以与示例中相同的方式调用restore事务时，一切似乎都很好。看起来他没有出错。但我等了3到10分钟，这足够我从谷歌服务器上获取EOS了。但是没有回应…我不知道我做了什么

这是我用于恢复传输的代码

mBillingService.restoreTransactions(); 

public boolean restoreTransactions() {
    return new RestoreTransactions().runRequest();
}
class RestoreTransactions extends BillingRequest {
    long mNonce;

    public RestoreTransactions() {
        // This object is never created as a side effect of starting this
        // service so we pass -1 as the startId to indicate that we should
        // not stop this service after executing this request.
        super(-1);
    }

    @Override
    protected long run() throws RemoteException {
        mNonce = Security.generateNonce();

        Log.d("running", "running restore request");
        Bundle request = makeRequestBundle("RESTORE_TRANSACTIONS");
        request.putLong(Consts.BILLING_REQUEST_NONCE, mNonce);
        Bundle response = mService.sendBillingRequest(request);
        logResponseCode("restoreTransactions", response);
        return response.getLong(Consts.BILLING_RESPONSE_REQUEST_ID,
                Consts.BILLING_RESPONSE_INVALID_REQUEST_ID);
    }

    @Override
    protected void onRemoteException(RemoteException e) {
        super.onRemoteException(e);
        Security.removeNonce(mNonce);
    }

    @Override
    protected void responseCodeReceived(ResponseCode responseCode) {
        ResponseHandler.responseCodeReceived(BillingService.this, this, responseCode);
    }
}   

事实上这和地下城的样本是一样的。但我没有得到任何回应。但是如果我想买一件东西，没有问题。 有人知道如何解决这个问题吗？我正在收到关于购买的回复，但没有关于恢复的回复

毕竟，如果我完成了我的意图并完成了我的应用程序，那么就会出现以下错误。似乎在应用程序结束后才有响应。它不会在跑步时出现，而是在完成所有意图后出现

另一件奇怪的事情是，在destroy上，我正在为计费解除服务和上下文的绑定。那么事实上，这是否应该被称为？我想没有

有人知道如何解决这个问题吗？ 提前谢谢
