No, this is wrong. - If you are putting normal objects (primitives, Parcelable, Serializable) into the Bundle, they will be copied and re-instantiated as the Intent travels into the system process and back to your app.
- If you put IBinder objects in, a reference to the object will be transfered, and you will receive back either the original object (if in the same process) or a proxy object (if in another process). And please: DO NOT PUT IBINDER OBJECTS IN TO INTENTS. In most places hopefully the framework prevents this. If you do, your app will break occasionally, when its process gets killed and the activity using the object is re-instantiated.
