Generics in Kotlin provide a powerful way to write reusable and type-safe code. However, on the Java Virtual Machine (JVM), generics are subject to type erasure, meaning that the specific type arguments used for instances of a generic class are not preserved at runtime. This limitation has implications for runtime type checks and casts. But fear not! Kotlin provides a solution: reified type parameters. In this blog post, we’ll delve into the world of reified type parameters and explore how they enable us to access and manipulate type information at runtime.
Generics in Kotlin are implemented using type erasure on the JVM. This means that the specific type arguments used for instances of a generic class are not preserved at runtime. In this section, we’ll explore the practical consequences of type erasure in Kotlin and learn how you can overcome its limitations by declaring a function as inline.
By declaring a function as inline, you can prevent the erasure of its type arguments. In Kotlin, this is achieved by using reified type parameters. Reified type parameters allow you to access and manipulate the actual type information of the generic arguments at runtime.
In simpler terms, when you mark a function as inline with a reified type parameter, you can retrieve and work with the specific types used as arguments when calling that function.
Now, let’s look at some examples to better understand the concept of reified type parameters and their usefulness.
Generics in Kotlin, similar to Java, are erased at runtime. This means that the type arguments used to create an instance of a generic class are not preserved at runtime. For example, if you create a List<String> and put strings into it, at runtime, you will only see it as a List. You won’t be able to identify the specific type of elements the list was intended to contain. However, the compiler ensures that only elements of the correct type are stored in the list based on the type arguments provided during compilation.
Let’s consider the following code:
val list1: List<String> = listOf("a", "b")
val list2: List<Int> = listOf(1, 2, 3)Even though the compiler recognizes list1 and list2 as distinct types, at execution time, they appear the same. However, you can generally rely on List<String> to contain only strings and List<Int> to contain only integers because the compiler knows the type arguments and enforces type safety. It is possible to deceive the compiler using type casts or Java raw types, but it requires a deliberate effort.
When it comes to checking the type information at runtime, the erased type information poses some limitations. You cannot directly check if a value is an instance of a specific erased type with type arguments. For example, the following code won’t compile:
if (value is List<String>) { ... } // Error: Cannot check for instance of erased typeEven though you can determine at runtime that value is a List, you cannot determine whether it’s a list of strings, persons, or some other type. That information is erased.
Note that erasing generic type information has its benefits: the overall amount of memory used by your application is smaller; because less type information needs to be saved in memory.
As we stated earlier, Kotlin doesn’t let you use a generic type without specifying type arguments. Thus you may wonder how to check that the value is a list, rather than a set or another object
To check if a value is a List without specifying its type argument, you can use the star projection syntax:
if (value is List<*>) { ... }By using List<*>, you’re essentially treating it as a type with unknown type arguments, similar to Java’s List<?>. In this case, you can determine that the value is a List, but you won’t have any information about its element type.
Note that you can still use normal generic types in as and as? casts. However, these casts won’t fail if the class has the correct base type but a wrong type argument because the type argument is not known at runtime. The compiler will emit an “unchecked cast” warning for such casts. It’s important to understand that it’s only a warning, and you can still use the value as if it had the necessary type.
Here’s an example of using as? cast with a warning:
fun printSum(c: Collection<*>) {
val intList =
c as? List<Int> // Warning here. Unchecked cast: List<*> to List<Int>
?: throw IllegalArgumentException("List is expected")
println(intList.sum())
}This code defines a function called printSum that takes a collection (c) as a parameter. Within the function, a cast is performed using the as? operator, attempting to cast c as a List<Int>. If the cast succeeds, the resulting value is assigned to the variable intList. However, if the cast fails (i.e., c is not a List<Int>), the as? operator returns null, and the code throws an IllegalArgumentException with the message “List is expected”. Finally, the sum of the integers in intList is printed.
Let’s see how this function behaves when called with different inputs:
printSum(listOf(1, 2, 3)) // o/p - 6When called with a list of integers, the function works as expected. The sum of the integers is calculated and printed.
Now let’s change the input to a set:
printSum(setOf(1, 2, 3)) // o/p - IllegalArgumentException: List is expectedWhen called with a set of integers, the function throws an IllegalArgumentException because the input is not a List. The as? cast fails, resulting in a null value, and the IllegalArgumentException is thrown.
Now we pass String as input:
printSum(listOf("a", "b", "c")) // o/p - ClassCastException: String cannot be cast to NumberWhen called with a list of strings, the function successfully casts the list to a List<Int>, despite the wrong type argument. However, during the execution of intList.sum(), a ClassCastException occurs. This happens because the function tries to treat the strings as numbers, resulting in a runtime error.
The code examples above demonstrate that type casts (as and as?) in Kotlin may lead to runtime exceptions if the casted type and the actual type are incompatible. The compiler emits an “unchecked cast” warning to notify you about this potential risk. It’s important to understand the meaning of these warnings and be cautious when using type casts.
The code snippet below shows an alternative approach using an is check:
fun printSum(c: Collection<*>) {
val intList =
c as? List<Int> // Warning here. Unchecked cast: List<*> to List<Int>
?: throw IllegalArgumentException("List is expected")
println(intList.sum())
}In this example, the printSum function takes a Collection<Int> as a parameter. Using the is operator, it checks if c is a List<Int>. If the check succeeds, the sum of the integers in the list is printed. This approach is possible because the compiler knows at compile time that c is a collection of integers.
So, Kotlin’s compiler helps you identify potentially dangerous type checks (forbidding
ischecks) and emits warnings for type casts (asandas?) that may cause issues at runtime. Understanding these warnings and knowing which operations are safe is essential when working with type casts in Kotlin.
In Kotlin, generics are typically erased at runtime, which means that you can’t determine the type arguments used when an instance of a generic class is created or when a generic function is called. However, there is an exception to this limitation when it comes to inline functions. By marking a function as inline, you can make its type parameters reified, which allows you to refer to the actual type arguments at runtime.
Let’s take a look at an example to illustrate this. Suppose we have a generic function called isA that checks if a given value is an instance of a specific type T:
fun <T> isA(value: Any) = value is TIf we try to call this function with a specific type argument, like isA<String>("abc"), we would encounter an error because the type argument T is erased at runtime.
However, if we modify the function to be inline and mark the type parameter as reified, like this:
inline fun <reified T> isA(value: Any) = value is TNow we can call isA<String>("abc") and isA<String>(123) without any errors. The reified type parameter allows us to check whether the value is an instance of T at runtime. In the first example, the output will be true because "abc" is indeed a String, while in the second example, the output will be false because 123 is not a String.
Another practical use of reified type parameters is demonstrated by the filterIsInstance function from the Kotlin standard library. This function takes a collection and selects instances of a specified class, returning only those instances. For example:
val items = listOf("one", 2, "three")
println(items.filterIsInstance<String>())In this case, we specify <String> as the type argument for filterIsInstance, indicating that we are interested in selecting only strings from the items list. The function’s return type is automatically inferred as List<String>, and the output will be [one, three].
Here’s a simplified version of the filterIsInstance function’s declaration from the Kotlin standard library:
inline fun <reified T> Iterable<*>.filterIsInstance(): List<T> {
val destination = mutableListOf<T>()
for (element in this) {
if (element is T) {
destination.add(element)
}
}
return destination
}Reification works for inline functions because the compiler inserts the bytecode implementing the inline function directly at every place where it is called. This means that the compiler knows the exact type used as the type argument in each specific call to the inline function.
When you call an inline function with a reified type parameter, the compiler can generate a bytecode that references the specific class used as the type argument for that particular call. For example, in the case of the filterIsInstance<String>() call, the generated code would be equivalent to:
for (element in this) {
if (element is String) {
destination.add(element)
}
}The generated bytecode references the specific String class, not a type parameter, so it is not affected by the type-argument erasure that occurs at runtime. This allows the reified type parameter to be used for type checks and other operations at runtime.
It’s important to note that inline functions with reified type parameters cannot be called from Java code. Regular inline functions are accessible to Java as regular functions, meaning they can be called but are not inlined. However, functions with reified type parameters require additional processing to substitute the type argument values into the bytecode, and therefore they must always be inlined. This makes it impossible to call them in a regular way, as Java code does not support this mechanism.
Also, one more thing to note is that an inline function can have multiple reified type parameters and can also have non-reified type parameters alongside the reified ones. It’s important to keep in mind that marking a function as inline does not necessarily provide performance benefits in all cases. If the function becomes large, it’s recommended to extract the code that doesn’t depend on reified type parameters into separate non-inline functions for better performance.
Reified type parameters can be especially useful when working with APIs that expect parameters of type java.lang.Class. Let\’s explore two examples to demonstrate how reified type parameters simplify such scenarios.
ServiceLoader The ServiceLoader API from the JDK is an example of an API that takes a java.lang.Class representing an interface or abstract class and returns an instance of a service class implementing that interface. Traditionally, in Kotlin, you would use the following syntax to load a service:
val serviceImpl = ServiceLoader.load(Service::class.java)However, using a function with a reified type parameter, we can make this code shorter and more readable:
val serviceImpl = loadService<Service>()To define the loadService function, we use the inline modifier and a reified type parameter:
inline fun <reified T> loadService(): T {
return ServiceLoader.load(T::class.java)
}Here, T::class.java retrieves the java.lang.Class corresponding to the class specified as the type parameter, allowing us to use it as needed. This approach simplifies the code by specifying the class as a type argument, which is shorter and easier to read compared to ::class.java syntax.
Simplifying startActivity in Android In Android development, when launching activities, instead of passing the class of the activity as a java.lang.Class, you can use a reified type parameter to make the code more concise. For instance:
inline fun <reified T : Activity> Context.startActivity() {
val intent = Intent(this, T::class.java)
startActivity(intent)
}With this inline function, you can start an activity by specifying the activity class as a type argument:
startActivity<DetailActivity>()This simplifies the code by eliminating the need to pass the activity class as a java.lang.Class instance explicitly.
Reified type parameters allow us to work with class references directly, making the code more readable and concise. They are particularly useful in scenarios where APIs expect java.lang.Class parameters, such as ServiceLoader in Java or starting activities in Android.
Reified Type parameters in Kotlin have certain restrictions that you need to be aware of. Some of these restrictions are inherent to the concept itself, while others are determined by the implementation of Kotlin and may change in future Kotlin versions. Here’s a summary of how you can use reified type parameters and what you cannot do:
Reified type parameters can be used in type checks and casts. You can check if an object is of a specific type or perform a type cast using the reified type parameter. Here’s an example:
inline fun <reified T> checkType(obj: Any) {
if (obj is T) {
println("Object is of type T")
} else {
println("Object is not of type T")
}
val castedObj = obj as? T
// Perform operations with the casted object
}Reified type parameters can be used with Kotlin reflection APIs, such as ::class, to access runtime information about the type. It allows you to retrieve the KClass object representing the type parameter. Here’s an example:
inline fun <reified T> getTypeInformation() {
val typeInfo = T::class
println("Type information: $typeInfo")
}Reified type parameters can also be used to obtain the corresponding java.lang.Class object of the type using the ::class.java syntax. This can be useful when interoperating with Java APIs that require Class objects. Here’s an example:
inline fun <reified T> getJavaClass() {
val javaClass = T::class.java
println("Java class: $javaClass")
}Reified type parameters can be used as type arguments when calling other functions. This allows you to propagate the type information to other functions without losing it due to type erasure. Here’s an example:
inline fun <reified T> processList(list: List<T>) {
// Process the list of type T
for (item in list) {
// ...
}
}
fun main() {
val myList = listOf("Hello", "World")
processList<String>(myList)
}These examples demonstrate the various ways in which reified type parameters can be utilized in Kotlin, including type checks, reflection APIs, obtaining java.lang.Class, and passing the type information to other functions as type arguments.
Reified type parameters cannot be used to create new instances of the class directly. You can only access the type information using reified type parameters. To create new instances, you would need to use other means such as reflection or factory methods. Here’s an example:
inline fun <reified T> createInstance(): T {
// Error: Cannot create an instance of the type parameter T
return T()
}Reified type parameters cannot directly access the companion object of the type parameter class. However, you can access the class itself using T::class syntax. To call methods on the companion object, you would need to access it through the class reference. Here’s an example:
inline fun <reified T> callCompanionMethod(): String {
// Error: Cannot access the companion object of the type parameter T
return T.Companion.someMethod()
}When calling a function with a reified type parameter, you cannot use a non-reified type parameter as a type argument. Reified type parameters can only be used as type arguments themselves. Here’s an example:
inline fun <reified T> reifiedFunction() {
// Error: Non-reified type parameter cannot be used as a type argument
anotherFunction<T>()
}
fun <T> anotherFunction() {
// ...
}Reified type parameters can only be used in inline functions. You cannot mark type parameters of classes, properties, or non-inline functions as reified. Reified type parameters are limited to inline functions. Here’s an example:
class MyClass<T> { // Error: Type parameter cannot be marked as reified
// ...
}
val <T> List<T>.property: T // Error: Type parameter cannot be marked as reified
get() = TODO()
fun <T> nonInlineFunction() { // Error: Type parameter cannot be marked as reified
// ...
}These examples illustrate the restrictions on reified type parameters in Kotlin. By understanding these limitations, you can use reified type parameters effectively in inline functions while keeping in mind their specific usage scenarios.
Reified type parameters in Kotlin offer a powerful tool for overcoming the limitations of type erasure at runtime. By utilizing reified type parameters in inline functions, developers can access and manipulate precise type information, enabling type checks, casts, and interaction with reflection APIs. Understanding the benefits and restrictions of reified type parameters empowers Kotlin developers to write more expressive, type-safe, and concise code.
By embracing reified type parameters, Kotlin programmers can unleash the full potential of generics and enhance their runtime type-related operations. Start utilizing reified type parameters today and unlock a world of type-aware programming in Kotlin!

App Cloning is undoubtedly one of the most highly anticipated features in Android. In the past, users had to resort to downloading third-party app cloning utilities that often came bundled with spyware. However, with Android 14, Google plans to address this by introducing a native App Cloning utility.
App Cloning allows you to have two instances of the same app on your device. This feature is particularly useful for users with dual SIM phones who want to use multiple accounts of apps like WhatsApp simultaneously. By cloning the app and logging in with a secondary SIM card, you can have two separate accounts running concurrently.
Google initially hinted at the App Cloning feature during the Android 14 Developer Preview 1. However, there haven’t been any recent updates regarding its development. It is speculated that App Cloning may not be included in the initial stable release of Android 14. However, it is expected to be introduced in future Android 14 feature drop updates, specifically for Pixel users.
The addition of a native App Cloning utility will bring convenience and ease of use to Android users who require multiple instances of certain apps. While its exact timeline for availability remains uncertain, it is an exciting feature to look forward to in future updates of Android 14.
Predictive back gestures were introduced in Android 14 Developer Preview 2 but were later removed in the following preview. These gestures allowed users to perform a slow back swipe to reveal the underlying app layer. This was particularly useful when you couldn’t remember the previous page or layer you were on.
By using predictive back gestures, you could check the layer below without losing the contents of the current page. It gave you the flexibility to verify if the previous layer was the one you intended to navigate to.
Initially, this feature was only supported in the Settings app and a few other system apps. However, it remains uncertain whether predictive back gestures will be included in the first stable release of Android 14. If not, there’s a possibility that it will be added in future feature updates.
While the fate of predictive back gestures in Android 14 is unclear, it presented an interesting way to navigate within apps and explore layers. We will have to wait and see if it becomes a part of the official release or is introduced in future updates.
During Google I/O 2023, Google unveiled a feature called App Pair, which will be introduced in Android 14 later this year. This feature, showcased during the Pixel Fold announcement, allows users to pair and use apps together in split screens. You can also minimize or maximize them simultaneously.
At first glance, App Pair may not appear particularly useful for smartphones. However, with the increasing popularity of tablets, this feature could be a game-changer. It offers a compelling reason why Android tablets are no longer considered inferior to iPads.
With App Pair, users will have the ability to multitask more effectively on larger screens. By pairing apps in split screens, you can simultaneously use two apps side by side, enhancing productivity and convenience. Whether it’s taking notes while reading, watching a video while browsing the web, or messaging while referencing another app, App Pair makes multitasking on Android tablets a seamless experience.
The inclusion of App Pair in Android 14 demonstrates Google’s commitment to enhancing the tablet experience and bridging the gap between Android tablets and their competitors.

In Android 14, a new screen recording feature called “Partial Screen Recording” may be introduced. Despite its name, it doesn’t mean recording only a selected area of the screen. Instead, it allows you to record a specific app without capturing any UI elements or notifications that might appear on the screen.
This feature works similarly to how Discord handles screen sharing. When you switch to view another app or the home screen during the recording, the recorded content will appear black. However, as soon as you switch back to the app you want to record, the content will be visible again. It’s a clever and convenient way to focus solely on recording the app without any distractions.
While the availability of the Partial Screen Recording feature in the official release of Android 14 is not confirmed, it is an exciting addition that can enhance the screen recording experience for users. So, keep an eye out for this neat feature in future Android updates.
One exciting feature that Android 14 is expected to bring is the ability to drag and drop text and images between apps, similar to what iOS 15 offers. In the Android 14 Beta 3 build, you can already experience this feature with text, and it works seamlessly.
To use the text drag and drop feature, simply select the text you want to move, long press on it, and then drag it to another app where you want to paste the text. With your other hand, switch to the desired app and drop the text into the text area. It’s a convenient way to transfer text quickly and easily between different apps.
While the current beta version only supports text drag and drop, it is anticipated that the final Android 14 release will also include the ability to drag and drop images. This will allow you to effortlessly move images from one app to another, enhancing your productivity and ease of use.
Keep an eye out for the official Android 14 update to enjoy the full drag and drop functionality, making it simpler and more convenient to transfer both text and images between apps on your Android device.
One of the challenges with adaptive mono icons in Android 12 is that app developers need to add support for them. Without proper support, the overall experience may feel incomplete. However, in Android 13, Google introduced a feature that automatically converts icons to themed icons if they are not supported by developers. This helpful feature may also make its way to Android 14.
Currently, the Pixel launcher has a hidden flag that allows users to force themed icons, which has been present since Android 13 QPR Beta 3. This suggests that Google might enable this feature in the future. If enabled, it will contribute to a seamless and intuitive Android experience, ensuring that the icons match the overall theme of the device.
With automatic icon conversion, users won’t have to worry about inconsistent or mismatched icons on their devices. Android 14 aims to enhance the visual cohesiveness of the user interface, making it more polished and pleasing to the eye.
Keep an eye out for this feature in the upcoming Android 14 release, as it has the potential to improve the overall aesthetic and user experience on your Android device.
Android 14 introduces a range of features and improvements that enhance user experience. It offers customization options like LockScreen customizations and Emoji wallpaper pickers, along with privacy enhancements such as Tracker Prevention alerts. Quality of life improvements includes the Photo Picker feature and Notification Flashes. The update brings camera advancements, App Cloning utility, predictive back gestures, and the ability to use Android devices as external cameras. Android 14 promises a seamless and personalized experience, focusing on user customization and functionality.
