The way to just write single-line for permission more easy?
In this article, you’ll learn how to handle Android runtime permissions from Android Marshmallow using coroutines. This approach will make it easy to handle permissions in Android components with very short code. After reading this article, You’ll no longer need to deal with callback and
If you don’t choose the right architecture for your Android project, you will have a hard time maintaining it as your codebase grows and your team expands.
Android architecture is the way you structure your Android project code so that your code is scalable and easy to maintain. Developers spend more time maintaining a project than initially building it, so it makes sense to follow a proper architectural pattern.
In Android, MVC refers to the default pattern where an Activity acts as a controller and XML files are views. MVVM treats both Activity classes and XML files as views, and…
Implement validation for Android. Developers should focus on their awesome code, and let the library do the boilerplate. And what’s more, this could help keep your layout file clean. Provide a rich set of validators to cover most various types of Text field. Develop and reuse your own validator easily.
Android WorkManager is a background processing library which is used to execute background tasks which should run in a guaranteed way but not necessarily immediately. With WorkManager we can enqueue our background processing even when the app is not running and the device is rebooted for some reason. WorkManager also lets us define constraints necessary to run the task e.g. network availability before starting the background task.
Android WorkManager is a part of Android Jetpack (a suite of libraries to guide developers to write quality apps) and is one of the Android Architecture Components (collection of components that help developers…
In this lesson, on android alarm manager we will see how a alarm manager works.
Let us go thorough alarm manager in now in general we know that alarm is a task of making us know that a particular time has arrived to do any task like early in the morning to wake up and so on..
In the same way we will provide our program with alarm manager to let it know when to do a task by scheduling it.When …
Note: These tips are ordered based on your familiarity with Kotlin so you can easily skip to tips that suit your skill level.
There are several benefits to lazy loading. Lazy loading can result in faster startup time, since loading is deferred to when the variable is accessed. This is particularly useful in using Kotlin for an Android app as opposed to a server app. For Android apps, we want to reduce app startup time so that the user sees the app content faster, rather than sitting at an initial loading screen.
Lazy loading like this is also…
In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn’t a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.
Design patterns can speed up the development process by providing tested, proven development paradigms. Effective software design requires considering issues that may not become visible until later in the implementation. …
The Lambda function is similar to an anonymous function. An Anonymous function is a function which does not have a name. Basically, Lambda expression is a way to create functions concisely and pass them as argument, return them, etc. We can call them as we call simple functions.
A Lambda expression can be treated as a variable. …
In this Lesson, we’ll be looking into kotlin higher-order functions.
Kotlin functions are first-class, which means that they can be stored in variables and data structures, passed as arguments to and returned from other higher-order functions. You can operate with functions in any way that is possible for other non-function values.
To facilitate this, Kotlin, as a statically typed programming language, uses a family of function types to represent functions and provides a set of specialized language constructs, such as lambda expressions.
A higher-order function is a function that takes functions as parameters, or returns a function.
A function which…
