Question

即将推出的Google政策发生变化，迫使我们实施一个对话框，通知欧盟用户有关广告和分析的Cookie /设备标识符使用情况。我想只向欧盟用户展示此对话框。我不想使用其他权限（例如android.permission.ACCESS_COARSE_LOCATION）。因此，我创建了一个测试欧盟用户的功能：

的Android

boolean showCookieHint()
{
    final SharedPreferences settings = getSharedPreferences("localPreferences", Context.MODE_PRIVATE);
    if (settings.getBoolean("termsAccepted", true)  == false) return false;

    List<String> list = new ArrayList<String>();
    list.add("AT"); //Austria
    list.add("BE"); //Belgium

我的功能是否足以检测到欧盟用户？

以下是基于Betatester先生使用枚举回答的Android代码。我注意到芬兰失踪了，西班牙错误地进入了两次。我还删除了origin下的代码重复。

/* is eu time zone id */

Answer 2

同样的功能，但在Swift中。唯一的区别是我使用Parse的用户而不是NSUserDefaults。

class CookieHelper {

static func show() -> Bool {
    if PFUser.currentUser().valueForKey("cookieConsent") != nil {
        return false
    }
    let networkInfo: CTTelephonyNetworkInfo = CTTelephonyNetworkInfo.new()
    if let carrier: CTCarrier = networkInfo.subscriberCellularProvider {
        var euCountries = [String]()
        euCountries.append("AT") // Austria
        euCountries.append("BE") // Belgium
        euCountries.append("BG") // Bulgary
        euCountries.append("HR") // Croatia
        euCountries.append("CY") // Cyprus
        euCountries.append("CZ") // Czech Republic
        euCountries.append("DK") // Denmark
        euCountries.append("EE") // Estonia
        euCountries.append("FI") // Finland
        euCountries.append("FR") // France
        euCountries.append("GF") // French Guiana
        euCountries.append("PF") // French Polynesia
        euCountries.append("TF") // French Southern Territories
        euCountries.append("DE") // Germany
        euCountries.append("GR") // Greece
        euCountries.append("HU") // Hungary
        euCountries.append("IE") // Ireland
        euCountries.append("IT") // Italy
        euCountries.append("LV") // Latvia
        euCountries.append("LT") // Lithuania
        euCountries.append("LU") // Luxembourg
        euCountries.append("MT") // Malta
        euCountries.append("NL") // Netherlands
        euCountries.append("PL") // Poland
        euCountries.append("PT") // Portugal
        euCountries.append("RO") // Romania
        euCountries.append("SK") // Slovakia
        euCountries.append("SI") // Slovenia
        euCountries.append("ES") // Spain
        euCountries.append("SE") // Sweden
        euCountries.append("GB") // United Kingdom of Great Britain and Northern Ireland

        // EU Sim/Network
        let sim: String? = self.formatCountryCode(carrier.isoCountryCode)
        let net: String? = self.formatCountryCode(carrier.mobileCountryCode)
        if sim != nil || net != nil {
            for country in euCountries {
                if sim != nil {
                    if country == sim {
                        println("EU User (sim)")
                        return true
                    }
                }
                if net != nil {
                    if country == net {
                        println("EU User (net)")
                        return true
                    }
                }
            }
        }
    }

    // EU Local time zone
    if self.timeZoneContainsEurope(NSTimeZone.localTimeZone()) {
        return true
    }
    // EU Default time zone
    if self.timeZoneContainsEurope(NSTimeZone.defaultTimeZone()) {
        return true
    }

    return false
}

private static func formatCountryCode(countryCode: String?) -> String? {
    if countryCode != nil && count(countryCode!) == 2 {
        return countryCode!.uppercaseString
    } else {
        return nil
    }
}

private static func timeZoneContainsEurope(timeZone: NSTimeZone) -> Bool {
    let time: NSString = timeZone.name.lowercaseString
    if count(time as! String) > 10 {
        return time.containsString("europe")
    }
    return false
}

}

Answer 3

String ACCEPTED_COOKIES_KEY = "accepted-cookies";
final List<String> euCountries = new ArrayList<String>() {
    {
        addAll(Arrays.asList(new String[] {
            "be", "bg", "cz", "dk", "de", "ee", "ie", "el", "es", "fr", 
            "hr", "it", "cy", "lv", "lt", "lu", "hu", "mt", "nl", "at", 
            "pl", "pt", "ro", "si", "sk", "fi", "se", "uk"
            }));
    }
};


TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    String networkCountryIso = null;

    if(telephonyManager != null) {
        networkCountryIso = telephonyManager.getNetworkCountryIso();
    }

    if(euCountries.contains(networkCountryIso)) {
        final SharedPreferences prefs = context.getSharedPreferences(PREFERENCES_FILE, Context.MODE_PRIVATE);
        if (!prefs.getBoolean(ACCEPTED_COOKIES_KEY, false)) {
            new AlertDialog.Builder(context)
            .setTitle("Cookies")
            .setMessage("Your message for visitors here")
            .setNeutralButton("Close message", new OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    prefs.edit().putBoolean(ACCEPTED_COOKIES_KEY, true).commit();
                }
            }).show();
        }
    }

以上代码是最好的方法。值得注意的是：

    mTelephonyManager.getSimCountryIso()

不应该使用

，因为这表示SIM提供商的母国（例如，Vodaphone UK SIM将返回“gb”，Vodaphone德国SIM将返回“de”）而不是当前位置（国家）设备。当用户漫游时，这种差异很大。
