    Strategy for in-app updates: use Google library or custom solution ?

    Posted: 03 Oct 2020 06:51 AM PDT

    Looking at app version stats lately, it came to my attention that a significant number of users are using older versions of my app.

     

    Hence the utility to notify users of available updates in app so they can optionally update. I would only do optional updates, not forced ones.

    There's the Google in-app update library for this, but looks rather heavy and complicated and I can see that thing causing unforeseen crashes already.

     

    I wonder if a simple custom solution detecting if a newer version is published (easy with Firebase config) and if that's the case showing a dialog with some explanation text and a button that goes to the Play Store page app of the app, would not be better. The advantages I can see is:

    • straightforward to implement
    • can control the text displayed to the user to incentivize him to update (if only mentioning that updates fixes bugs and add new functionality)
    • way easier to test

     

    Any thoughts and experience on this ?

    Experience with Google's In-App Review API: 100% increase in total ratings with the same average rating as before the in-app review. Not a bad thing at all.

    Tech stack for Augmented Reality app, oriented at drawing on faces ( sunglasses, masks etc. )

    Posted: 03 Oct 2020 12:58 AM PDT

    Maybe someone has recent experience with this type of stuff. Also not sure what to explore, even though #2 seems like exact match.

    1. ML kit for Android + CameraX - saw guide on ML kit with CameraX, but no idea how to operate with 3d models there.
    2. ARcore - seems to be built with what I need in mind, thought the Sceneform is deprecated, and the only way to go with it seems to be using Unity + ARcore, which doesn't sound a pleasant experience looking at what people say. SO Post with details on Sceneform deprecation here.

    Are there any recommendations/tips on whether choosing ARcore + Sceneform is the safe option here ( since you can migrate to unity if really needed in the future )?

    Data acces design advice

    Posted: 03 Oct 2020 07:56 AM PDT

    I would like to hear your opinions on what would be the best design for the following use.

    My app makes use of contacts provider quite a lot. I have favourites, call log, contacts pages on my main viewpager and all start loading from contacts provider when app is opened.

    Favourites load started contacts, Call logs loads call log and then matches number to contact by searching in contacts provider (which could be up to 2000 logs) and finally Contacts fragment loads all contacts (some people have over 5000 contacts) .

    There lies my problem. They all race each other and this slows down pulling data from contacts provider.

    For now I have implemented a caching mechanism. I use coroutines, lock loading contacts with mutex and delay with 'while' until contacts loaded to cache.

    This works fine if user has avarage amount of contacts. Load time is usually less than a second. Things get ugly if user has too many contacts.

    Obviously it is not ideal as all requests to my repo has to wait until cache is filled.

    I thought about creating some sort of repo that starts loading contacts as soon as app is crated, observe this loading in view models and only then start loading favourites, call logs etc. after cache is filled.

    Although this wouldn't solve loading many contacts issues, it would allow me to remove lock and delay while cache is filled.

    What would be a better way to handle this situation?

    Posted: 02 Oct 2020 03:37 PM PDT

    Hello,

    Im a developer from germany and we have to create a "Gewerbe", thats like a registered one person company with limitations on income etc and it has to contain your personal full name. (e.g. "Mike tyson" solutions)

    Can I create any made up name for the developer account that will be shown under my app name and have just on my bills for admob and purchases my the registered "Gewerbe" comapy name (Mike tyson solutions)?

    Maybe there are developers as well from germany with experience on that or some one in general who can help me out :)

    Google Maps Optimization

    Posted: 02 Oct 2020 11:41 PM PDT

    I am using Google Maps in the app I am building, and it is overall working well but I am looking for an optimization. When I use Google Maps itself on my phone, it will always recommend locations near me, but when I use it in the app, it will show autofill from all over the world. Is there a way to limit the radius to the country the user is in or to prioritize regional locations in autofill?

    Android Studio C++ syntax support?

    Posted: 02 Oct 2020 11:15 PM PDT

    Hi. I'm having a little issue.

    While working on my work Mac the AS gives nice full support for C++ files syntax, lint etc. but I can't get it to work with the same version of AS at home on my Ubuntu it just displays everything as simple txt file (*.cpp, *.hpp and CMake files too).

    Both AS are 4.0.1 and have NDK configured in the project structure windows. Both compile and run the app correctly - it's just that working without IntelliJ syntax support is a nightmare.

    Writing this cause I could not find any similar issue anywhere and maybe someone might have had the same problem.

    What's the best way to implement drawer menus?

    Posted: 02 Oct 2020 08:55 PM PDT

    Hi!

    I just recently started in the world of android dev, in my first app I used a drawer menu but since I had no knowledge of fragments I had to copy-paste my drawer menu in all of my activities, next time I'm planning to use fragments with my drawer menu but since there are a lot of things I still don't know I want to ask.

    What are the best practices when implementing drawer menus?

    [Beginner] Staring from scratch. Seeking advice.

    Posted: 02 Oct 2020 09:12 PM PDT

    Hi folks. I have been working as software developer for 4 years, mainly working as backend/SRE kinda role with golang/kuberentes/linux admin/nodejs. I have been toying with the idea of learning to make mobile apps. I was quite impressed with swiftui, but unfortunately my current financial condition won't allow me to invest in apple ecosystem for buying its hardware.

    I have decided to learn with jetpack compose by following official tutorial. I have to l earn kotlin as well, and i don't know java. How difficult it would be for me learn this tech? If you were at my position what would you do differently? Any suggestions, advice would be very helpful.

    Simple Login System

    Posted: 02 Oct 2020 09:27 PM PDT

    I am trying to make a simple login system using sharedPreferences. I wanted to know how can I make a different profile page for different users based on their input on the login page, as i am using sharedPreferences, there are only few users so i can make different profile pages for each user, but i dont know how i can do it. I tried using putExtra with intent, but i cannot get the intent from an Activity to a Fragment.

    If you guys have some tips on making a login system, no matter using sharedPreferences or Database, please help me out. I am using Kotlin

    Thank you :)

    Do cross-platform SDKs like Flutter and React Native have a good future on the job market?

    Posted: 02 Oct 2020 11:18 AM PDT

    I know most companies are hiring Java, Kotlin, C# or Swift developers but do technologies like Flutter and React Native have a chance to be something in demand in the near future? I still have a few years left before I graduate and I'm fairly decent on Flutter since I've been doing personal projects but I'm wondering if I should just ditch it and make apps on Kotlin or Java so that I have more experience on those instead.
