The FAQ mentions a method of passing objects around activities.
(It is not clear to me):
"A HashMap of WeakReferences to Objects
You can also use a HashMap of WeakReferences to Objects with Long
keys. When an activity wants to pass an object to another activity, it
simply puts the object in the map and sends the key (which is a unique
Long based on a counter or time stamp) to the recipient activity via
intent extras. The recipient activity retrieves the object using this
key."
Trying to pass a StringBuilder to another activity,
// trailBuilder is a StringBuilder
WeakHashMap wkmap = new
WeakHashMap<String,StringBuilder>();
wkmap.put("trailBuilder", trailBuilder);
alertIntent.putExtra("trailBundle",wkmap); // compile
ERROR here
Can anyone point me to an example of how this is done?
thanks,
Anil
