Almost in every app, you have the Login screen for the user to enter the credentials. In most cases, the Login Activity referred to the welcome screen or user first screen for Application. In this article, we’re going to make a Login screen for Android App. To create a Login screen, I’m going to take this design from…
Previously in our Room persistence article, we’ve discussed what are the basics of Room and how to simply work with it. Also, we’ve made a book library app using the Room persistence basic components. (If you haven’t read the previous article, I highly recommend you read it before proceeding it.) In this article, we’re gonna…
In this article, we’re going to explore the Transformations of LiveData. Sometime there may be a case where you want to changes in the LiveData value before dispatching it to the Observer or you may need to return different LiveData based on some condition. Here comes the concept of Transformations. In the last article, we’ve…
Today I wanna tell you about a few solutions that have been developed. Solutions for problems that I think all of us as a developer have been trying to solve again and again in every project. So, let’s say that I want to perform actions in response to changes in lifecycle status of Android Component….
We all want good power efficiency right..? Like batteries that last a long time. We want to build really cool apps and we do not want the user to manage between these things. Like do I want to build cool apps, or do I want power efficiency. It’s terrifically difficult to make that choice. So,…
Chaining the Worker is the most attractive features of WorkManager. With the work manager, we can easily chain multiple workers together and the run workers in a particular order. I’ve written some pretty good articles on WorkManager before. In these articles, I briefly explain how to use the work manager, setting input and output data,…
We all want to make our app reactive, less boilerplate code, the power of asynchronous and observable queries. The good news is Room library supports async queries which return LiveData or RxJava2 observable types. The LiveData and Observables allow you to get an automatic update whenever the data changes. Now let’s say we need to read all…
In the last article, we discussed how we can set input and output data with WorkManager API. (If you haven’t read the previous article I highly recommended you to read before proceeding.) In this article, we’re going to learn how we can convert multiple output results into one input using InputMerger. I also wrote a pretty…
Couple of years ago, when I’m studying at my University. We have given the assignment to make a color changer app. The app is very basic where we have only one button and when a user clicks the button it changes its background color. So like I said, the app is very basic and I’ve made…
When working with WorkManager you may need to pass the argument for your task and also need some result to return. To pass the arguments to a task you need to setInputData to when creating the WorkRequest object. The input data method takes a Data object. Note: By the way, I wrote a pretty good…
