You haven t stated what you do with the prefsEditor object after this  but in order to persist the preference data  you also need to use   prefsEditor commit

Here s a take on using Kotlin Delegated Properties that I picked up from here  but expanded on and allows for a simple mechanism for getting setting SharedPreference properties    For String  Int  Long  Float or Boolean  it uses the standard SharePreference getter s  and setter s   However  for all other data classes  it uses GSON to serialize to a String  for the setter  Then deserializes to the data object  for the getter   Similar to other solutions  this requires adding GSON as a dependency in your gradle file   implementation  com google code gson gson 2 8 6    Here s an example of a simple data class that we would want to be able to save and store to SharedPreferences   data class User val first  String  val last  String    Here is the one class that implements the property delegates   object UserPreferenceProperty   PreferenceProperty lt User gt       key    USER OBJECT       defaultValue   User first    Jane   last    Doe        clazz   User  class java   object NullableUserPreferenceProperty   NullablePreferenceProperty lt User   User gt       key    NULLABLE USER OBJECT       defaultValue   null      clazz   User  class java   object FirstTimeUser   PreferenceProperty lt Boolean gt           key    FIRST TIME USER           defaultValue   false          clazz   Boolean  class java    sealed class PreferenceProperty lt T   Any gt  key  String                                           defaultValue  T                                           clazz  Class lt T gt     NullablePreferenceProperty lt T  T gt  key  defaultValue  clazz    Suppress  UNCHECKED CAST   sealed class NullablePreferenceProperty lt T   Any   U   Any gt  private val key  String                                                             private val defaultValue  T                                                             private val clazz  Class lt U gt     ReadWriteProperty lt Any  T gt         override fun getValue thisRef  Any  property  KProperty lt   gt    T   HandstandApplication appContext   getPreferences                run                   when                       clazz isAssignableFrom String  class java  -

I had trouble using the accepted answer to access Shared Preference data across activities   In these steps  you give getSharedPreferences a name to access it   Add the following dependency in the build gradel  Module  app  file under Gradle Scripts   implementation  com google code gson gson 2 8 5    To Save   MyObject myObject   new MyObject    set variables of  myObject   etc   SharedPreferences mPrefs   getSharedPreferences  Name   Context MODE PRIVATE    Editor prefsEditor   mPrefs edit    Gson gson   new Gson    String json   gson toJson myObject   prefsEditor putString  Key   json   prefsEditor commit      To Retrieve in a Different Activity   SharedPreferences mPrefs   getSharedPreferences  Name   Context MODE PRIVATE    Gson gson   new Gson    String json   mPrefs getString  Key        MyObject obj   gson fromJson json  MyObject class

You can save object in preferences without using any library  first of all your object class must implement Serializable   public class callModel implements Serializable    private long pointTime  private boolean callisConnected   public callModel boolean callisConnected   long pointTime        this callisConnected   callisConnected      this pointTime   pointTime    public boolean isCallisConnected         return callisConnected    public long getPointTime         return pointTime         Then you can easily use these two method to convert object to string and string to object    public static  lt T extends Serializable gt  T stringToObjectS String string        byte   bytes   Base64 decode string  0       T object   null      try           ObjectInputStream objectInputStream   new ObjectInputStream new ByteArrayInputStream bytes            object    T  objectInputStream readObject          catch  Exception e            e printStackTrace              return object      public static String objectToString Parcelable object        String encoded   null      try           ByteArrayOutputStream byteArrayOutputStream   new ByteArrayOutputStream            ObjectOutputStream objectOutputStream   new ObjectOutputStream byteArrayOutputStream           objectOutputStream writeObject object           objectOutputStream close            encoded   new String Base64 encodeToString byteArrayOutputStream toByteArray    0          catch  IOException e            e printStackTrace              return encoded      To save   SharedPreferences  mPrefs   getPreferences MODE PRIVATE   Editor prefsEditor   mPrefs edit    prefsEditor putString  MyObject   objectToString callModelObject    prefsEditor commit      To read  String value  mPrefs getString  MyObject        MyObject obj   stringToObjectS value

If your Object is complex I d suggest to Serialize XML JSON it and save those contents to the SD card  You can find additional info on how to save to external storage here  http   developer android com guide topics data data-storage html filesExternal

User · Answer

If you want to store the whole Object that you get in response  It can achieve by doing something like   First Create a method that converts your JSON into a string in your util class as below    public static  lt T gt  T fromJson String jsonString  Class lt T gt  theClass        return new Gson   fromJson jsonString  theClass       Then In Shared Preferences Class Do something like    public void storeLoginResponse yourResponseClass objName         String loginJSON   UtilClass toJson customer       if   TextUtils isEmpty customerJSON             editor putString AppConst PREF CUSTOMER  customerJSON           editor commit              and then create a method for getPreferences  public Customer getCustomerDetails         String customerDetail   pref getString AppConst PREF CUSTOMER  null       if   TextUtils isEmpty customerDetail             return GSONConverter fromJson customerDetail  Customer class         else           return new Customer              Then Just call the First method when you get response and     second when you need to get data from share preferences like  String token   SharedPrefHelper get   getCustomerDetails   getAccessToken      that s all   Hope it will help you   Happy Coding

Better is to Make a global Constants class to save key or variables to fetch or save data   To save data call this method to save data from every where   public static void saveData Context con  String variable  String data        SharedPreferences prefs   PreferenceManager getDefaultSharedPreferences con       prefs edit   putString variable  data  commit        Use it to get data   public static String getData Context con  String variable  String defaultValue        SharedPreferences prefs   PreferenceManager getDefaultSharedPreferences con       String data   prefs getString variable  defaultValue       return data      and a method something like this will do the trick  public static User getUserInfo Context con        String id    getData con  Constants USER ID  null       String name    getData con  Constants USER NAME  null       if id    null  amp  amp  name    null                    User user   new User      Hope you will have a user Object              user setId id               user setName name                 Here set other credentials              return user            else     return null
