Bitmap |
get()
Returns an instance of the wrapped resource.

Class<Bitmap> |
getResourceClass()
Returns the
Class of the wrapped resource. |
int |
getSize()
Returns the size in bytes of the wrapped resource to use to determine how much of the memory
cache this resource uses.
|
void |
initialize()
Called on a background thread so the
Resource can do some eager initialization. |
static BitmapResource |
obtain(Bitmap bitmap,
BitmapPool bitmapPool)
Returns a new
BitmapResource wrapping the given Bitmap if the Bitmap is
non-null or null if the given Bitmap is null. |
void |
recycle()
Cleans up and recycles internal resources.

Note - This does not have to be the same instance of the wrapped resource class and in fact
it is often appropriate to return a new instance for each call. For example,
Drawable
s should only be used by a single
View
at a time so each call to this method for Resources that wrap
Drawable
s should always return a new
Drawable
.

It is only safe to call this method if there are no current resource consumers and if this method has not yet been called. Typically this occurs at one of two times:
