Android Passing Bitmap Through Activity

Question

i currently have a class that uses bitmap. however it is not serializable due to bitmap. Right now i am wondering which are the best ways to deal with it.

Should i be storing it on the cache or sdcard? How ong does bitmap saved in cache or sdcard stays? is there any tutorial for doing those

You can pass bitmap object from one activity to another.Take a look at the following:

Bitmap implements Parcelable, so you could always pass it in the intent:

Intent intent = new Intent(this, NewActivity.class);
intent.putExtra("BitmapImage", bitmap);

and retrieve it on the other end:

Bitmap bitmap = (Bitmap) intent.getParcelableExtra("BitmapImage");
