SecureStorageImplementation

[leadanymind]

Hi,

I have an application that has an android project, an iOS project, and a portable class library. I was wondering if there was a way I can store the code to provide session management inside of my portable class library. I'm also not sure where to set the SecureStorageImplementation.StorageType = StorageTypes.PasswordProtectedFile for sdk versions lesser than 26. I'm currently trying to implement this logic inside of my portable class library as a service that can be tested. The idea is to use the code in the portable class library for both iOS and android. I haven't been able to find any relatable examples in the samples you provided in the repo. This is my class implementation.

 public class SessionService :  ISessionService
    {
        /// <summary>
        /// Method to retrieve an access token stored by <see cref="StoreSessionToken(SessionRequest)"/>
        /// </summary>
        /// <returns><see cref="SessionResponse"/></returns>
        public SessionResponse RetrieveSessionToken()
        {
            var accessToken = CrossSecureStorage.Current.GetValue("AccessToken");

            if (!string.IsNullOrWhiteSpace(accessToken))
            {
                return new SessionResponse() { Data = accessToken };
            }

            return new SessionResponse() { ErrorMessage = "Could not retrieve access token" };
        }

        /// <summary>
        /// Stores an access token used to maintain a logged in users permissions.
        /// </summary>
        /// <param name="request"><see cref="SessionRequest"/></param>
        /// <returns>bool in order indicate success.</returns>
        public bool StoreSessionToken(SessionRequest request)
        {
            CrossSecureStorage.Current.SetValue("AccessToken", request.Data);

            return CrossSecureStorage.Current.HasKey("AccessToken");
        }

        /// <summary>
        /// Clears out the token used to store a session.
        /// </summary>
        /// <returns>bool in order to indicate success.</returns>
        public bool ClearSessionToken()
        {
            CrossSecureStorage.Current.DeleteKey("AccessToken");

            return CrossSecureStorage.Current.HasKey("AccessToken");
        }

        public void SetBackwardsCompatibleSettings()
        {

            //Plugin.SecureStorage.SecureStorageImplementation secureStorage = new Plugin.SecureStorage.SecureStorageImplementation();

                //secureStorage .StorageType = Plugin.SecureStorage.StorageTypes.PasswordProtectedFile;
        }

I figured it out. Apparently you need to install the package in both the portable class library and the android and ios projects.
