修复Xamarin Android

Question

如您所知，Android开发者：

  

从2017年3月1日开始，Google Play将阻止发布任何新的应用或更新，其中PreferenceActivity类可能容易受到碎片注入攻击

在页面https://support.google.com/faqs/answer/7188427中，它提供了有关如何修复此漏洞的一些建议但是使用Xamarin开发的应用程序呢？

我无法找到任何相关信息。它说我受影响的类是SettingActivity，它继承自PreferenceActivity，我的类SettingActivity是这样的：

 [Activity(
    Label = "@string/ApplicationName",
    Icon = "@drawable/ic_launcher",
    Theme = "@android:style/Theme.Holo.Light",
    ParentActivity = typeof(MainActivity))]
[IntentFilter(
    new [] {Intent.ActionManageNetworkUsage},
    Categories= new [] {Intent.CategoryDefault}
)]
public class SettingsActivity : PreferenceActivity
{
    public static readonly string KeyWifiOnly = "pref_wifi_only";

    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        AddPreferencesFromResource(Resource.Xml.preferences);

        ActionBar.SetHomeButtonEnabled(true);
        ActionBar.SetDisplayHomeAsUpEnabled(true);

        PreferenceManager.SetDefaultValues(this, Resource.Xml.preferences, false);

        SetupNetworkPreferences();
    }

    private void SetupNetworkPreferences()
    {
        var prefs = PreferenceManager.GetDefaultSharedPreferences(this);

        ListPreference list = FindPreference(
            AppSettings.PreferenceNetworkProvider) as ListPreference;

        list.SetEntries(
            Enum.GetNames(typeof(AppSettings.FtpHostNetwork)));

        list.SetEntryValues(Enum
            .GetValues(typeof(AppSettings.FtpHostNetwork))
            .Cast<int>()
            .Select(x => x.ToString())
            .ToArray());
    }

    protected override void OnResume()
    {
        base.OnResume();

        var tracker = (Application as App).Tracker;
        tracker.Screen("PantallaPreferencias");
    }
}

正如Mike Ma在评论中所建议的那样：

添加exported = false propierty工作正常。

[Activity( Label = "@string/ApplicationName", Exported =false, Icon = "@drawable/ic_launcher", Theme = "@android:style/Theme.Holo.Light", ParentActivity = typeof(MainActivity))]
