'get(String!): Any?' is deprecated in Java, is there an alternative?

Question

I've got a line of code like this:

val smsRetrieverStatus = extrasObj?.get(SmsRetriever.EXTRA_STATUS) as Status

But it's now deprecated as shown:

Is there any alternative way of doing this without getting deprecation warnings?

Answer 1

If you read the method documentation here, it says:

This method was deprecated in API level 33. Use the type-safe specific APIs depending on the type of the item to be retrieved, eg. getString(java.lang.String)

So, they're telling you to stop using the generic get() method, and instead use a type-specific one -- getString(), getInt(), getLong(), etc.

Update: If you have a custom class or data type, then you'll need to implement your own logic to serialize that class (maybe use something like Gson). And once you've serialized it into a String, you can then use getString()

Answer 2

You can try another method

val status = extrasObj?.getParcelable(SmsRetriever.EXTRA_STATUS, Status::class.java)

Note that this method is not stable and sometimes throws NPE. So you'd better catch and handle the NPE.
