本文记录了一个在实现in_appbillingfeature过程中遇到的问题：在添加信用卡界面时程序崩溃。崩溃原因是尝试在未授权支付的国家使用支付功能，提供了解决此问题的方法。

今天做in_app billing feature时发现一个问题，当进行到 添加 Credit Card界面里程序会crash （下图是在play store里支持付费app时的界面，会遇到同样的问题，所以用在此处作为参照）


点击 Continue之后 就会Crash... Crash 信息如下：

产生这个错误的原因是：Google 发现你处于没有被授权支付的国度。这好像是无法躲过检查的，SIM卡里的地理信息好像是伪装不了的。

When an invalid country (one not authorized/enabled for purchases like China) code is read from the SIM and not found in the list mCountries  ( BillingPreferences.BILLING_COUNTRIES ), the mSelectedCountry is set to  NULL:

private void setupWidgets(Bundle bundle)
{
     mSelectedCountry =
BillingUtils.findCountry(BillingUtils.getDefaultCountry(getActivity(), null),
mCountries);
     ...
     mBillingAddress.setAddressSpec(mSelectedCountry,
getAddressSpec(mSelectedCountry));
     ...

}

SUGGESTED FIX:
com.google.android.finsky.billing.creditcard.AddCreditCardFragment.getAddressSpecroutine should check parameter NULL condition.
