how to use getSharedPreferences in android

First get the instance of SharedPreferences using

SharedPreferences userDetails = context.getSharedPreferences("userdetails", MODE_PRIVATE);

Now to save the values in the SharedPreferences

Editor edit = userDetails.edit();edit.putString("username", username.getText().toString().trim());edit.putString("password", password.getText().toString().trim());edit.apply();

Above lines will write username and password to preference

Now to to retrieve saved values from preference, you can follow below lines of code

String userName = userDetails.getString("username", "");String password = userDetails.getString("password", "");

(NOTE: SAVING PASSWORD IN THE APP IS NOT RECOMMENDED. YOU SHOULD EITHER ENCRYPT THE PASSWORD BEFORE SAVING OR SKIP THE SAVING THE PASSWORD)

//Set PreferenceSharedPreferences myPrefs = getSharedPreferences("myPrefs", MODE_PRIVATE);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_PRIVATE);  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)
