关于如何在Google Play Store 购买付费APP

今天要测试项目的应用内支付功能,发现不好测试,在大陆无法付费。

想办法搞一张美国的SIM卡 ()

按这个http://noirbright.com/?p=530上面的教程,试了一下,模拟T_Mobile 运营商成功了! 电子市场里的应用可以正常下载。(有一个自己开发的APP,原来不能在国内下载的,现在可以下载使用了。)关于 付费APP的下载 ,我试了一下,发现当你进行到下面的界面的时候:(由于本人没有VISA 或者 MasterCard 卡,所以无法顺利完成测试)

然后再点击 Continue,就会crash ,如下图:

Crash的原因是:

java.lang.NullPointerException

产生这个错误的原因是: Google 还是可以发现你处于没有被授权支付的国度。这好像是躲不过去的,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.



而且:有些时候通信总是不稳定,有时候会出现如下图这样的情形:
