Question

Communicating between two threads, I use a Message, transporting the data. In my case, a HashMap. Now on reconstructing the data, I get a warning about an unchecked type cast. That would imply to me (as java noob), that I shouldn’t do that cast at all, right? But what would be the correct way to get the HashMap out of the bundle?

    Bundle dataBundle = msg.getData();
Serializable result = dataBundle.getSerializable("data");
HashMap<String,String> output = (HashMap<String, String>) result;

Thanx for any pointers!

Answer 1

So with your approach

getSerializable("data");

there is no way to do it without casting because getSerializable method always returns Serializable instance.

Without casting you could use getParcelableExtra that returns T but i know anything about your application context so i’m not sure if it’s possible to use.
