android - Android - 欧盟Cookie法

即将出台的谷歌政策改变了，迫使我们实施一个对话，通知欧盟用户关于广告和分析使用cookie/设备标识符的情况。我只想向欧盟用户显示此对话框。我不想使用其他权限（例如android.permission.ACCESS_COARSE_LOCATION）。因此，我创建了一个功能来测试欧盟用户：

我的功能是否足以检测欧盟用户？

最佳答案

下面是一些改进的Android代码，基于betatester先生使用枚举的答案。我注意到芬兰失踪了，西班牙两次误入。我还删除了/* is eu time zone id */下的代码副本。

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 {
        final TelephonyManager tm = (TelephonyManager) activity.getSystemService(Context.TELEPHONY_SERVICE);
        if (tm.getPhoneType() != TelephonyManager.PHONE_TYPE_CDMA && tm.getPhoneType()!=TelephonyManager.PHONE_TYPE_NONE) {
            String networkCountry = tm.getNetworkCountryIso();
            if (networkCountry != null && networkCountry.length() == 2) {
                networkCountry = networkCountry.toUpperCase();

                if (EUCountry.contains(networkCountry)) {
                    Log.v(TAG, "is EU User (network)");
                    return true;
                }
            }
        }
    }
    catch (Exception e) { error = true; }

/* is eu time zone id */
    try {
        String tz = TimeZone.getDefault().getID().toLowerCase();
        if (tz.length() < 10) {
            error = true;
        } else if (tz.contains("euro")) {
            Log.v(TAG, "is EU User (time)");
            return true;
        }
    } catch (Exception e) {
        error = true;
    }


    if (error == true) {
        Log.v(TAG, "is EU User (err)");
        return true;

    return false;
