Suppose I have an activity to select an image from the gallery, and retrieve it as a BitMap, just like the example: here

Bitmap is Parcelable so you can add using [putExtra(String,Parcelable)][2] method, But not sure it is a best practice, If it is large size data it is better to store in a single place and use from both activities.
