If you are an android developer, you know how painful it is to code a simple list. You need to write a handful of code just to make a list working without any data in it. An RecyclerView.Adapter and ViewHolder if you remember.
I have had a tough time managing retrofit calls on android while making a REST calls to display something on UI. When the activity/fragment is destroyed you don't need the result anymore. You simply need to cancel that call else it may leak your activity.
It was May 17, 2017. I was on my desk with my laptop, to watch the live stream of Google I/O 2017. As always, I was waiting for the Google I/O Keynote, for some exciting announcements. And to my surprise, they announced official support for the language Kotlin on Android.
If you are an android developer, you know how much time it takes to get your code compiled. It's pretty annoying to wait for your builds to complete. Fortunately, there are some ways you can improve your builds. Go ahead and try out below mentioned methods. You will definitely see improvements.
Creating a process creates an persistence connection to the firebase, even if you app is in the background. So, disconnecting that open connection to the database when your app is not in use will save data as well as your precious simultaneous connections if you are on free Spark plan.
If you have ever been trying to retrieve a list of contacts with the phone numbers and emails in your application, you might have struggled initially. The same happened with me. But, when I decided to dive deeper, it was easy to understand (actually!). We will go through the basic structure to understand how they are stored (so that we can query correctly) and code snippet to quickly retrieve the list of contacts.
RecyclerView is a more advanced version of the ListView. RecyclerView is used for displaying large data sets that can be scrolled very efficiently by maintaining a limited number of views. To build a small list in RecyclerView, you need to write a lots of code. I have been using RecyclerView from almost 3-4 months, but everytime I just copied the code to get it work. It worked most of the time, but I never understood the code how it works. So when I watched this year’s I/O 2016 for RecyclerView I understood the basics why I need to write that much of code and how it works. It looks complex, but it isn’t.
