android - How to send objects through bundle

Question

I need to pass a reference to the class that does the majority of my processing through a bundle.

The problem is it has nothing to do with intents or contexts and has a large amount of non-primitive objects. How do I package the class into a parcelable/serializable and pass it to a startActivityForResult?

You can also use Gson to convert an object to a JSONObject and pass it on bundle. For me was the most elegant way I found to do this. I haven't tested how it affects performance.

In Initial Activity

Intent activity = new Intent(MyActivity.this,NextActivity.class);
activity.putExtra("myObject", new Gson().toJson(myobject));
startActivity(activity);

In Next Activity

String jsonMyObject;
Bundle extras = getIntent().getExtras();
if (extras != null) {
   jsonMyObject = extras.getString("myObject");
}
MyObject myObject = new Gson().fromJson(jsonMyObject, MyObject.class);
