getSerializableExtra and getParcelableExtra are deprecated. What is the alternative?

Question

I have upgraded targetSdkVersion and compileSdkVersion to 33.

I am now getting warnings telling me that the getSerializableExtra(name:) and getParcelableExtra(name:) methods are deprecated.

I checked and confirmed from the documentation in the Intent class that these two methods are indeed deprecated.

The documentation suggests that I use the new getSerializableExtra(name:clazz:) and getParcelableExtra(name:clazz:) methods instead.

Can anyone can help me use the new methods?

This is what I use:

inline fun <reified T : Serializable> Bundle.serializable(key: String): T? = when {
  Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU -> getSerializable(key, T::class.java)
  else -> @Suppress("DEPRECATION") getSerializable(key) as? T
}

inline fun <reified T : Serializable> Intent.serializable(key: String): T? = when {
  Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU -> getSerializableExtra(key, T::class.java)
  else -> @Suppress("DEPRECATION") getSerializableExtra(key) as? T
}

I've also written the same for getParcelable here and requested this to be added to the Support libraries directly

How can we get `ArrayList` from intent? – Rumit Patel Aug 30 '22 at 14:31
That's not what you asked in your original question – Niklas Aug 30 '22 at 14:50
Okay man, the question is updated. – Rumit Patel Aug 31 '22 at 07:01

@Niklas You should use Build.VERSION_CODES.TIRAMISU instead of 33. Also, here's a request on the issue tracker to offer this (and the Parcelable one) on the support library: https://issuetracker.google.com/issues/243986223 – android developer Aug 31 '22 at 07:28

I personally prefer the integer variable as I get super confused with their code names. Both work fine :) – Niklas Aug 31 '22 at 18:25

method T getSerializableExtra(String, Class<T>) is introduced from android 33. so you shoud use an if block for devices using android below 33.

fun <T : Serializable?> getSerializable(activity: Activity, name: String, clazz: Class<T>): T
{
    return if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU)
               activity.intent.getSerializableExtra(name, clazz)!!
           else
               activity.intent.getSerializableExtra(name) as T
}

and then you can use it in your activity like this:

val myPOJOClass = getSerializable(this, "my_intent_key", MyPOJOClass::class.java)

Anyway, even after the Version check, the annoying hint that the method is deprecated still does not allow you to sleep peacefully :) – neronovs Aug 08 '22 at 08:15
This works fine. But how can we get `ArrayList` from intent? – Rumit Patel Aug 24 '22 at 09:48

@RumitPatel, you can use `getParcelableArrayList( "key", MyListItem.class )`. There is a wrong reference in the Javadoc pointing to `getParcelable( String, Class )` instead. – Konsumierer Sep 15 '22 at 14:43

Consider not using the double bang, but making the function nullable. – JacksOnF1re Dec 29 '22 at 11:39
@JacksOnF1re I agree, because if the value was not found for some reason, you will get an NPE – Adam Burley Jun 22 '23 at 11:33

However, Mohamad Seyedi's answer did the job. But it fails in the case of getting intent data from onActivityResult().

We can't get data using Activity's intent inside onActivityResult(). Below are the solutions I got.

Solution 1: Using extension function:

fun <T : Serializable?> Intent.getSerializable(key: String, m_class: Class<T>): T {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU)
        this.getSerializableExtra(key, m_class)!!
    else
        this.getSerializableExtra(key) as T
}

Usage:

val myPOJOClass = intent.getSerializable("my_intent_key", MyPOJOClass::class.java)

Solution 2: Using regular function:

fun <T : Serializable?> getSerializable(intent: Intent, key: String, m_class: Class<T>): T {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU)
        intent.getSerializableExtra(key, m_class)!!
    else
        intent.getSerializableExtra(key) as T
}

Usage:

val myPOJOClass = getSerializable(intent, "my_intent_key", MyPOJOClass::class.java)

For those of us who still use Java, this function does the trick:

@SuppressWarnings({"unchecked", "deprecation"})
@Nullable
public static <T extends Serializable> T getSerializable(@Nullable Bundle bundle, @Nullable String key, @NonNull Class<T> clazz) {
    if (bundle != null) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
            return bundle.getSerializable(key, clazz);
        } else {
            try {
                return (T) bundle.getSerializable(key);
            } catch (Throwable ignored) {
            }
        }
    }
    return null;
}

Inspired by Mohamad's answer, you can do an extension

fun <T : Serializable?> Bundle.getSerializableCompat(key: String, clazz: Class<T>): T {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) getSerializable(key, clazz)!! else (getSerializable(key) as T)
}

and call it everywhere like this:

   arguments?.getSerializableCompat("my_key", MyClass::class.java)

Haven't used it myself till yet . As the doc says the updated method is

T getSerializableExtra(String, Class<T>) So you can use it as follows i think.

val myPOJOClass = intent.getSerializableExtra("my_intent_key", MyPOJOClass::class.java)

this method only works for android 33 and above. if you use it in devices using android < 33, you will receive a crash... – Mohamad Seyedi Jul 16 '22 at 11:55

That's pretty obvious since its been added in 33 . you have to put a version check .. – ADM Jul 16 '22 at 11:56

val myPojoClass = getSerializable(intent, "key_name_here", MyPojoTypeClass::class.java)

then, create that function

 private fun <T : Serializable?> getSerializable(intent: Intent, key: String, className: Class<T>): T {
        return if (Build.VERSION.SDK_INT >= 33)
            intent.getSerializableExtra(key, className)!!
        else
            intent.getSerializableExtra(key) as T
    }

Expanding upon Rumit Patel's answer, using an inline function with reified type parameter, usage is even simpler. Note that I made the return type nullable, because !! should in my opinion only be used as a last resort (or at caller side).

@Suppress("DEPRECATION")
inline fun <reified T : Serializable> Intent.getSerializable(key: String): T? {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU)
        this.getSerializableExtra(key, T::class.java)
    else
        this.getSerializableExtra(key) as? T
}

@Suppress("DEPRECATION")
inline fun <reified T : Parcelable> Intent.getParcelable(key: String): T? {
    Timber.d("intentextras parce")
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        this.getParcelableExtra(key, T::class.java)
    } else {
        this.getParcelableExtra(key)
    }
}

@Suppress("DEPRECATION")
inline fun <reified T : Parcelable> Intent.getParcelableArrayList(key: String): ArrayList<T>? {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        this.getParcelableArrayListExtra(key, T::class.java)
    } else {
        this.getParcelableArrayListExtra(key)
    }
}

Usage:

val mode1: Mode = intent.getSerializable("key")
val mode2 = intent.getSerializable<Mode>("key")

You can use top functions to serialize arguments

but I had a problem serializing the List of object

You can use this way to put and get serialized argument data

Because List is not a Serializable Class, you need to convert it to Array List that supports serializable

These functions are used for serializable

 inline fun <reified T : Serializable> Bundle.serializable(key: String): T? = 
     when {
        Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU -> 
            getSerializable(key, T::class.java)
        else -> @Suppress("DEPRECATION") getSerializable(key) as? T
     }

inline fun <reified T : Serializable> Intent.serializable(key: String): T? = 
    when {
       Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU -> 
           getSerializableExtra(key, T::class.java)
       else -> @Suppress("DEPRECATION") getSerializableExtra(key) as? T
    }

and this way handle puts serialized List of objects

  class YourFragment: Fragment {

      private latinit var list: List<YourObject>


      fun newInstance(
           listOfYourObject: List<YourObject>
       ): YourFragment {

           val args = Bundle()
           val yourList= ArrayList<YourObject>()
           yourList.addAll(listOfYourObject)
           args.putSerializable(LIST_KEY, yourList)
        
           val fragment = YourFragment()
           fragment.arguments = args
           return fragment
       }

   }

and now can get serialize of your list object in this way

   override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    requireArguments().serializable<ArrayList<YourObject>>(LIST_KEY)?.let{
        list = it.toList()
    }
   
 }

getSerializableExtra and getParcelableExtra are deprecated. What is the alternative?
