Which is better? Working on multiple smalls apps with different small ideas or working on a big giant app with a big idea?

Posted: 26 Dec 2017 10:52 AM PST

Hey, let me introduce myself. I am 21-year old doing bachelor in Computer Science and paying all my stuff myself by developing Android apps. I am confused about how to grow my own brand or make my self-introduce to the world? I have few ideas in mind few small and few large which one should I chase first? I know it is a weird question but this subreddit helped me a lot of time. So I think it will do this time too.

Does/Where Google use Kotlin for its own apps?

Posted: 26 Dec 2017 12:53 AM PST

Hi,

I discussed with an iOS developers colleague which told me that, Apple is only using Swift on the Calculator app on iOS, and in the Dock of the new macOS and that many of Apple internal developers continuing to develop in Objective-C for now, when the Apple developers community is encouraged to go with Swift directly (= use your developers community as betatester).

Which leads me, because I'm on the Android side, to questioning myself about where does Google use Kotlin today, except from GitHub samples code?

There is three ways, in order of benefits, for me to promote Kotlin: 1) show that some AOSP/Google Apps are now in Kotlin or partially written in Kotlin; 2) update developers.android.com with Kotlin code, today it's purely a JavaDoc with only Java classes documentation; 3) rewrite some of the Android base framework Java classes with Kotlin parts.

And it seems none of these are in the roadmap for now...

How to Make a Game?

Posted: 26 Dec 2017 03:16 PM PST

Hi, I played games all my life and would like to make one,but I have nearly 0 experience. I love Japanese role playing games, such as Golden sun and Pokémon. Golden sun is by far my favorite RPG of all time, the battle Djinn system is amazingly fun and fast paced.

I got the idea of combining the two games and would love to make an AAA title full game with no micro transactions nor ads.

So like a new Nintendo DS game at $39.99 but for android/Apple mobile phones instead. Sound crazy?

but to make this game from no experience sounds ludacris. Where should one even start?

Dealing with redundant state rendering when using MVI

Posted: 26 Dec 2017 03:13 PM PST

I've been using MVI in an app I'm working on, and for the most part I've been loving all of the benefits that it provides.

I've been running into something that's a little bit annoying though, and I'm not quite sure how to deal with it

Essentially, your activity's render(state) method is called every single time your state changes.

The issue is that render will render every single thing from the state, even if only one property was changed. This is totally redundant and could lead to performance issues if you're not careful

So far I've dealt with this by wrapping parts of my rendering code in checks like this

if (adapter.data !== state.data) { adapter.data = state.data }

This is really annoying to do when your state has a lot of properties though, and sometimes performing a redundancy check isn't so simple.

Does anyone have a better way of approaching this? Or is this simply a limitation of MVI that you can't really avoid?

Trying to install Android Studio on Ubuntu 17.10 but keep getting an error.

Posted: 26 Dec 2017 02:09 PM PST

Every time I try to download I get this error:

"Unable to run mksdcard SDK tool. One common reason for this failure is missing required libraries Please fix the underlying issue and retry."

I've tried most of the common suggestions but have no idea what to do. Any help would be extremely appreciated.

Android Paging Library

Posted: 26 Dec 2017 01:46 AM PST

I'm using the new Paging Library with a RecyclerView and custom DataSource and PagedList (i.e. without LiveData or Room).

My DataSource gets its data from an API.

I was wondering if the manual call of PagedList.loadArount(int) is mandatory to get an "endless scroll" feature ? At first glance, I was thinking of this library to provide a complete mecanism to call the new load of data automatically when the recyclerView has reached the end of the scroll.

Are there any reasons for feature modules other than instant apps support?

Posted: 26 Dec 2017 05:28 AM PST

I have this side project using clean arch with layer modules and I was considering refactoring it to feature modules instead. But then I realized it's a huge refactoring task, and I'm not really sure I see a point for it, because the only thing I was thinking of is 'so you don't need to look in several modules to understand a feature', but because there would probably be modules that would be common to several features anyway, that thought seems a bit of a fallacy.

Show layout bounds developer options tile not available?

Posted: 25 Dec 2017 06:09 PM PST

There used to be a developer tile to quickly turn on show/hide layout bounds. http://www.androidpolice.com/2016/05/19/android-n-developer-preview-3-has-two-new-dev-focused-quick-settings-night-mode-has-disappeared-but-is-still-sort-of-accessible/

I have a pixel 2. Is this available anywhere?

Is React Native the future of Android dev?

Posted: 26 Dec 2017 02:37 AM PST

So after learning Java in depth for a really long period I decided to finally learn Android development which is something I feel passionate about. But I attended a free seminar on the topic "React Native future of app development" They covered pretty good points on how we don't need to develop two different apps for Android and iOS with React Native.

So is react native is really the future of android apps, I've know the basics of JS. I can either start with Java or JS since I also feel interested about Web development. I am confused regarding what should I start with. Help appreciated.
