即将推出的Google政策更改，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：
Android的

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/* is eu time zone id */下的代码重复。
private enum EUCountry {
AT,BE,BG,HR,CY,CZ,DK,EE,FI,FR,DE,GR,HU,IE,IT,LV,LT,LU,MT,NL,PL,PT,RO,SK,SI,ES,SE,GB, //28 member states
GF,PF,TF, //French territories French Guiana,Polynesia,Southern Territories
EL,UK, //alternative EU names for GR and GB
ME,IS,AL,RS,TR,MK; //candidate countries
public static boolean contains(String s)
{
for (EUCountry eucountry:values())
if (eucountry.name().equalsIgnoreCase(s))
return true;
return false;
}
};
public static boolean isEU(Activity activity)
{
boolean error = false;
/* is eu sim */
try {
final TelephonyManager tm = (TelephonyManager) activity.getSystemService(Context.TELEPHONY_SERVICE);
String simCountry = tm.getSimCountryIso();
if (simCountry != null && simCountry.length() == 2) {
simCountry = simCountry.toUpperCase();
if (EUCountry.contains(simCountry)) {
Log.v(TAG, "is EU User (sim)");
return true;
}
}
}
catch (Exception e) { error = true; }
/* is eu network */
try {

networkCountry = networkCountry.toUpperCase();

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。

上面的代码是最好的方法。值得注意的是：
mTelephonyManager.getSimCountryIso()
不应该使用，因为这表示SIM提供商的本国（例如，Vodaphone UK SIM将返回“gb”，Vodaphone德国SIM将返回“de”）而不是设备的当前位置（国家）。当用户漫游时，这种差异很显着。
