At Google I/O 2019, Google announced that they were working on a new toolkit, Jetpack Compose, which would redesign how user interfaces (UI) are developed on the Android platform. In August 2020, the alpha version of Jetpack Compose was released. In this post, I will be examining how Compose differs from the current Android UI toolkits, and will discuss the benefits that the new program will bring to Android UI development.
Creating a successful application isn’t just about ensuring that all of the components work; the layout and design of the application are also crucial. The design must be professional and engaging, and the layout should be easy for users to navigate. Design components, such as animations and navigation transitions, can also enhance the usability of the application.
A mobile app is a great way to bring new ideas to life, add value for your customers, or boost awareness of your business—but only if you can build a quality mobile experience without breaking the bank. And nailing down the cost of an app in advance isn’t exactly easy. App development costs can range from trivial to extreme, depending on a host of factors such as what your app does, how users will interact with it, and how you plan to staff the project.
These days grocery stores are facing many challenges, like high maintenance costs, price competition with online stores, and limited business hours. All of these issues can be solved with unmanned grocery stores.
If you are building a mobile application of any sophistication, you are likely to need some services to support your app. You’ll need a way to distribute your app for testing prior to submitting to the app store(s), as well as analytics, error logging, crash reporting, and possibly user and data management services. Of course, you could write these services yourself and provision servers to host these services, but why do that when you don’t have to?
Your company needs a mobile app and you want to save money (of course). You want the app live last week, and you’d really like to avoid hiring Android and iOS devs on top of your existing web team.
Kotlin is a JVM language that hit version 1.0 about a year ago (February 2016).
It is developed by JetBrains, the same people who make my favorite suite of
IDEs. The language itself is open-source under the Apache License 2.0 and is
developed as a community project over at kotlinlang.org. Kotlin is something
that I have become rather excited about over the past year. This post’s goal is
not to teach you Kotlin but to get you excited about it!
Pixel density is the number of pixels per linear physical unit. Measured in pixels per inch (ppi or dpi). Pixel density and resolution are technically the same thing, but often people say “resolution” to mean “pixel count,” a related metric:
count = densityH * width * densityV * height
When other things are held constant:
Working as developers, we are focused on the low level technical details of a product, being that a website or an app. This heads down approach often makes us not to pay attention to many high level details that are crucial to bring our product to success. The typical path for a developer, at least at the beginning, is to build an app, put it on the store and then see it fail miserably. If that has happened to your app, then this post is for you!
