android studio shared preferences

Define some statics to store the preference file name and the keys you’re going to use:
public static final String PREFS_NAME = "MyPrefsFile";
private static final String PREF_USERNAME = "username";
private static final String PREF_PASSWORD = "password";
You’d then save the username and password as follows:
getSharedPreferences(PREFS_NAME,MODE_PRIVATE)
        .edit()
        .putString(PREF_USERNAME, username)
        .putString(PREF_PASSWORD, password)
        .commit();
So you would retrieve them like this:
SharedPreferences pref = getSharedPreferences(PREFS_NAME,MODE_PRIVATE);   
String username = pref.getString(PREF_USERNAME, null);
String password = pref.getString(PREF_PASSWORD, null);

if (username == null || password == null) {
    //Prompt for username and password
}
Alternatively, if you don’t want to name a preferences file you can just use the default:
SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(this);

İnstalling firstt 
Windows:

  1. Download Windows wrapper script (Right click, Save Link As apktool.bat)
  2. Download apktool-2 (find newest here)
  3. Rename downloaded jar to apktool.jar
  4. Move both files (apktool.jar & apktool.bat) to your Windows directory (Usually C://Windows)
  5. If you do not have access to C://Windows, you may place the two files anywhere then add that directory to your Environment Variables System PATH variable.
  6. Try running apktool via command prompt
