Written by Avin Sharma, documenting my programming journey. Check out my Github.
An introduction to Kotlin. Learn how variables, loops, functions, classes, etc work in Kotlin.
In this post I explore Model-View-ViewModel(MVVM) architecture and show how I used ViewModel, LiveData and Repository components in my app to fetch data from Github API.
How to detect change in Android settings and how to add the current selection of a ListPreferences to its summary. In this post I go over how I implemented nSharedPreferenceChangeListener and added selected option as summary in the ListPreference.
Activities get killed or recreated all the time, knowing about the lifecycle of an activity can help us preserve state and data in events like our app being killed by Android, moving between Activities and screen rotations. In this post I give an overview of Activity Lifecycle, discuss the difference between UP and BACK in android and how I wasted a lot of time figuring out why the RecyclerView won't retain its data when moving between child and parent Activities.
In this post I go over how to create the settings screen we see on most of the apps and add a settings screen to the Github Repository App we have been working on.
In this post I go over how to create a simple menu in Android
