When interacting with apps on our devices, animations not only add delight to our experience but they also help to create a sense of connection between the destinations being animated. One of the animations on Android which I’ve always enjoyed is the exploding Floating Action Button animation. Here, the user clicks the FAB and it explodes to fill the whole screen, with the next screen being...
In the last post we took a look into Hilt and how, at a high level, it can be used for Dependency Injection in Android projects. Now that we have seen how the API can be used, I want to start taking deeper dives into how things are working under the hood. In this post we’re going to dive into the @HiltAndroidApp annotation – looking at what it does when it comes to generated code and...
When it comes to dependency injection on Android, we’ve seen over the past few years many different opinions, solutions and frustrations that have risen in the community – in this post we’re going to focus on Dependency Injection solutions and not Service Locators. To begin with we have Dagger – when I say this I mean vanilla dagger with no extra android support. This has...
When it comes to developing Android applications, ensuring or applications remain stable is vital to providing a good user experience. One of things we can do to help achieve this is by writing automated tests that run checks against the user interface of our application. When it comes to Jetpack Compose, things currently look a little different to how we might be used to writing these kind of...
When it comes to the layout of child components inside of their parents, it is likely we’re going to want to arrange them in some way on both the horizontal and/or vertical axis. For example, our parent may fill the height of the screen, but our child components may only represent a small amount of that height and we may want to arrange that to be at the bottom of the screen. The same applies...
When it comes to building our UI in jetpack compose, for a lot of applications it will come at a time when our UIs are already build using a mixture of existing solutions – be it XML layouts or custom views. It may even be the case that we have custom views in our current Android project that aren’t quite ready to be converted over to compose just yet, or maybe it doesn’t feel very...
If you’re enjoying my posts on Jetpack Compose, check out some details on the book I’ll be writing on Compose! When it comes to laying out groups of components in our screens, it’s not always the case that we want them to be sequentially displayed in a vertical or horizontal manner. There may be times in which we want to have some items drawn behind and/or on top of others. When this is...
If you’re enjoying my posts on Jetpack Compose, check out some details on the book I’ll be writing on Compose! When it comes to decorating views within Jetpack Compose, some components allow the use of a Border reference to outline a given component. Currently, the use of a Border reference is not too extensive and requires minimal effort to get in place. There are currently two ways to...
In the last section we looked at the Radio Button, allowing us to create a single selectable item. However, defining a group of these would require a collection of boilerplate logic as we’d have to manually handle the state for the group of buttons. When it comes to this scenario, Jetpack Compose contains a Radio Group which can be used to create a collection of radio buttons for single selection...
If you’re enjoying my posts on Jetpack Compose, check out some details on the book I’ll be writing on Compose! We previously looked at other checkable components and how they can be used to allow a toggleable state controller within our user interface. Alongside these other toggleable components we also have the Radio Button component. This button allows our users to select some...
