You need to use Localdatastore.

  1. in your android app enable it.

    Parse.Configuration config = new Parse.Configuration.Builder(this)
        .applicationId("XXXXXXXXXXX") 
        .clientKey("XXXXXXXXXXX")
        .server("https://api.serverused.com/")
        .enableLocalDataStore() // Acticate it here
        .build();

Parse.initialize(config);  //

  2. This is how to save the object or list of objects offline

     ParseQuery<ParseObject> query = ParseQuery.getQuery(“GameScore");
    query.getInBackground("xWMyZ4YE", new GetCallback<ParseObject>() {
    public void done(ParseObject object, ParseException e) {
       if (e == null) {

    // object will be your game score so save it offline
       object.pinAllInBackground();  
       } else {
    // something went wrong
    }
  }
});

  3. This is how to get your localdata

    ParseQuery<ParseObject> query = ParseQuery.getQuery(“GameScore");
    query.fromLocalDatastore();
    query.getInBackground("xWMyZ4YE", new GetCallback<ParseObject>() {
    public void done(ParseObject object, ParseException e) {
       if (e == null) {
    // object will be your game score
       } else {
    // something went wrong
    }
  }
});

If you are saving a list of objects, generally used with findInBackground, you will need to use

ParseObject.pinAllInBackground(objects);

Hope this helps and check the docs Parse LocalDataStore
