可靠的方法来获得用户是在国内？ [英] Reliable method to get the country the user is in?
问题描述
我通常会得到该国从设备的语言。它的工作原理，但现在我不得不承认巴西。和大多数的设备只有葡萄牙语（pt_PT），并没有葡萄牙语（巴西）选项。
I usually get the country from the device's language. It works but now I have to recognize Brazil. And most of the devices only have portuguese (pt_PT), and no portuguese (Brazil) option.
我查了一下这个线程：我在哪里？ - 获得国家
I checked this thread: Where am I? - Get country
方法
String locale = context.getResources().getConfiguration().locale.getCountry();
String locale = context.getResources().getConfiguration().locale.getDisplayCountry();
都还在语言而已，于事无补。
Are still language-only, doesn't help.
还有与SIM卡的建议，但我不知道这是否会可靠地工作（做所有的SIM卡有这种独特的身份？），也有点不正是我需要的，因为用户可以' T改变它（这是情况下，如果它是一个设置），它会排除使用设备用户无需SIM卡（也许他们只是使用WLAN）。
There's also the suggestion with the sim-card, but I'm not sure if this will work reliably (do all sim cards have this unique identification?), it's also a bit not exactly what I need because the user can't change it (which is the case if it was a setting), and it will exclude users using a device without sim-card (maybe they just use WLAN).
还有地理位置的建议，但在已停用它的设备这将可能无法正常工作。还是我错了？
There's also geolocation suggestion, but this will probably not work in devices which have deactivated it. Or am I wrong?
如果没有别的帮助我会让我的应用程序对话框或菜单设置，使用户可以选择它。不过，我想先确认是否有任何可靠的可能性与设备。
If nothing else helps I would make a dialog or menu setting in my app so the user can select it there. But I would first like to confirm if there's any reliable possibility with the device.
推荐答案
您可以拉的位置<一href="http://developer.android.com/reference/android/telephony/TelephonyManager.html#getNetworkCountryIso%28%29">from手机网络：
TelephonyManager.getNetworkCountryIso()
或<一href="http://developer.android.com/reference/android/telephony/TelephonyManager.html#getSimCountryIso%28%29">from SIM卡：
TelephonyManager.getSimCountryIso()
或者，如果have用户的电话号码，你可以将它通过
Or, if you have the user's phone number, you may be able to match it to the country through this data.
在理想情况下，你可以使用所有这三个（以某种顺序，也许是SIM卡，电话号码，然后网络），如果没有工作，使用反向地理定位作为最后的手段。
Ideally, you could use all three of these (in some order, perhaps SIM, Phone #, then Network), and if none works, use reverse geolocation as a last resort.
