    Is it hard for a lone dev to make a high earning android app?

    Posted: 25 Dec 2021 09:11 PM PST

    Do most high earning apps belong to companies and dev groups? How hard is it to be in the top 20% of earners as a lone dev? And what is better, to sell your app or continue earning on the playstore?

    Building a new Android TV launcher - with your help

    Posted: 26 Dec 2021 04:26 AM PST

    Hi all, Like many of you the latest changes to the default launcher from google that includes ads on the home screen didn't sit well with me.

    I've been meaning to get into using tools such as Hilt and Jetpack Compose and took the opportunity to start a new project using them.

    So far I've created a bare minimal, barebones, not ready to be used - but can technically be used launcher. It's just a grid where you can start applications from.

    The idea is that I want to build this from the beginning with the help of all of you. The direction it should take, the way it should look, the way it should behave etc.

    Things like, supporting customization, mimic other launcher or create something completely different are all open for discussion.

    Everything will be open, discussions and everything else will be done on this github project: https://github.com/nassendelft/tvlauncher

    Let me know what you think!

    How to track SQL query execution time while using Room?

    Posted: 25 Dec 2021 07:27 PM PST

    I am using the Room library to manage my Sqlite database and many of my queries are reactive (either uses LiveData or Flow).

    I am aware of enabling Sqlite logs using the ADB tool but that does not help me capture execution time programmatically. And also I cannot use old school start and end time wrappers around the queries since they are reactive.

    My use case is to send execution time data to Firebase Analytics if the time exceeds a certain threshold.

    Is launch { whenStarted {} } and launchWhenStarted { } exactly the same?

    Posted: 25 Dec 2021 11:38 PM PST

    Is the below exactly the same?

    lifecycleScope.launch { whenStarted { // Do something } } 

    and

    lifecycleScope.launchWhenStarted { // Do something } 

    Or they do have some distinct purpose, hence both APIs are provided?

    Best resources for clean architecture and mvvm.

    Posted: 26 Dec 2021 04:42 AM PST

    Currently I'm working on my very first jetpack application where I use firebase for authentication ( google or facebook ) and remote server for rest ( database ).

    I'm planning to use clean architecture and mvvm. So is there any resources where I can learn everything API ( get/post/put ), firebase authentication, checked authentication status.

    Thank in advance.

    Where do android devs work?

    Posted: 26 Dec 2021 02:54 AM PST

    I've slowly been studying kotlin and have made a couple of apps (purely for learning) and was wondering what a career for an android developer looks like.

    Is it all contract work? Or do a lot of larger enterprises actually need a full time native android dev? Or is there something else out there like a dev shop where they churn out apps and see what sticks?

    Are there any 3rd party State Management libs for Jetpack Compose?

    Posted: 26 Dec 2021 02:31 AM PST

    Hi there! I googled a lot before asking this question but unfortunately I did not find an answer. I developed few Flutter apps using libs like Riverpod and Bloc because native way of state management was not very flexible/scalable for me. Looks like the native way of state management in Jetpack Compose is also has the same issues. Are there any similar libs for Jetpack Compose? Thank you.

    Right way to implement offline support in apps

    Posted: 26 Dec 2021 02:26 AM PST

    Mostly we will show existing data till we fetch new data & after fetching will update ui right? There can be existing data may have updated & deleted. Should I fetch all available data from server & insert in local database if new & update if already exists. If so wouldn't it take very long to update ui after fetching data from server? I need the right way to implement this

    Need help with android lint rules

    Posted: 26 Dec 2021 02:02 AM PST

    I really stuck on this one and i dont know where to look for an answer. I am making an app In Russian language, and Russian typography rules state that there could not be any line breaks after some propositions. I want to find out of box solution, which will manage text in my app. Here is a git, which offers suitable solution, however it doesn't work in my project. I tried different combinations with maven url in repositories, but everything i get is "502 bad gateway", "Could not find io.github..." or other errors. Am i missing something or it simply doesn't work? Is there any other solutions? I am desperate, please help

    Is it good practice to call ViewModel methods from the observer while implementing mvvm?

    Posted: 25 Dec 2021 11:52 AM PST

    The way my design works, I call a ViewModel method from outside the observer to change the field of an object in my sqlite database. Then the observer is triggered and it does something after which I want to immediately set another field of my livedata.

    Right now I just do it from the observer by calling the relevant ViewModel method to change the field value but that means that exact same observer is triggered again. I don't know why but I get the feeling this sort of design is anti-pattern. So, I wanted to know whether there is an alternative to do this?

    Posted: 26 Dec 2021 02:58 AM PST

    Hi,

    What is considered a very high ROI (Return on Investment) to be in the top 1%-0.1% of the android apps? For example, if you invest £1000 a month on your app what could be really crazy high profit considered as in %?
