On Android, I am trying to send a custom broadcast message using a custom Intent and BroadcastListeners. I have some custom data, in the format:
List<Hashtable<String,List<String>>> data;
When trying to use:
intent.putExtra("mydata", data);
I get the error:
The method putExtra(String, boolean) in the type Intent is not applicable for the arguments (String, List<Hashtable<String,List<String>>>)
Looking at the Intent class, there are a bunch of public methods that overload putExtra(). However, none seem to meet the data that I am trying to send.
There seem to be a rather generic method
putExtra(String name, Bundle value)
However, I am not sure how to transform my data in to a Bundle to use this. Is this the right thing to do? Or is there a simpler method?
You want to have Serializable for putExtra(String name, Serializable s)
version. However, List
is an interface that does not extend Serializable
. Try to declare it as ArrayList
.
