[android] how to use getSharedPreferences in android

I have an application in which I have to implement a "Login" activity. I have these components:

1. EditText username
2. EditText password
3. Button Login
4. Button Cancel

I want that my application to remember the login details of the user once the user has logged in until the user would press the "log out" button. I'm not using preferences in my xml.

How do I get the getSharedPreferences(String name, int mode) to work in my application?

//Set Preference
SharedPreferences myPrefs = getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
SharedPreferences.Editor prefsEditor;  
prefsEditor = myPrefs.edit();  
//strVersionName->Any value to be stored  
prefsEditor.putString("STOREDVALUE", strVersionName);  
prefsEditor.commit();

//Get Preferenece  
SharedPreferences myPrefs;    
myPrefs = getSharedPreferences("myPrefs", MODE_WORLD_READABLE);  
String StoredValue=myPrefs.getString("STOREDVALUE", "");

Try this..

If someone used this:

val sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context)

PreferenceManager is now depricated, refactor to this:

val sharedPreferences = context.getSharedPreferences(context.packageName + "_preferences", Context.MODE_PRIVATE)

After reading around alot, only this worked: In class to set Shared preferences:

 SharedPreferences userDetails = getApplicationContext().getSharedPreferences("test", MODE_PRIVATE);
                    SharedPreferences.Editor edit = userDetails.edit();
                    edit.clear();
                    edit.putString("test1", "1");
                    edit.putString("test2", "2");
                    edit.commit();

In AlarmReciever:

SharedPreferences userDetails = context.getSharedPreferences("test", Context.MODE_PRIVATE);
    String test1 = userDetails.getString("test1", "");
    String test2 = userDetails.getString("test2", "");
