    Weekly "anything goes" thread!

    Posted: 01 May 2020 05:40 AM PDT

    Here's your chance to talk about whatever!

    Although if you're thinking about getting feedback on an app, you should wait until tomorrow's App Feedback thread.

    Remember that while you can talk about any topic, being a jerk is still not allowed.

    "New User Acquired" is much less than "Users Lost" and still I the active installs are growing?

    As you can see, the "New Users Acquired" is more than half less than what the "Users Lost" card is showing. If we do the math, I have lost 74K users. And that should affect the active installs very negatively. Or I am missing something. Please help,

    How do I make my app design properly responsive?

    Posted: 01 May 2020 01:35 PM PDT

    Hi intermediate app dev here! I want to ask a question, how do I make my app responsive to different phone screen sizes? I know there's layout folders like small, normal and large but those are for different devices and dont work, on my 5.7inch a5 or 7inch a70. I've tried so many different things but none seem to have any efffect on my phones.

    So can anyone will tell me or link me to something that can actually work, because god damn is implementing design into android studio a pain.

    What's the 1 week path to get started with native Android app development?

    Posted: 01 May 2020 03:41 PM PDT

    Hi,

    I have development experience of some years in JavaScript and also done some java, python. I would like to get started with native Android development (kotlin is the way to go, right?). This is a requirement for my new job position. I want to have 1 week learning path that gives a high level overview of the kotlin language, Android development environment, Android app libraries, jargon and maybe build a simple app. Any good concise tutorials? Thanks.

    So if I use MediaPlayer.create().start() in my source code to play music for my app, it works fine on an actual phone but on the emulator, the music is played with consistent disruptions but if I keep hitting the button repeatedly, it gradually plays better... any reason why?

    Google Console App Publish times...

    Posted: 01 May 2020 12:43 PM PDT

    Hi Guys, I understand Google are taking 7 days or so to review apps for publishing. I added my app on the 22nd April! I am literally holding back a marketing budget for it to go live. What is taking so long!?!? I presumed 7 days maybe 8. But I am now down 9 days and counting... what gives? Is it selfish to feel annoyed?

    Is there a repo where I can find the most commonly used UI layout files?

    Posted: 01 May 2020 12:02 PM PDT

    For example, a list view of say an image and a text view.

    I am finding it very frustrating to build the UI.

    Which is kind of demotivating me. Don't really know why.

    I can happily write code for activities, fragments viemodels, adapter and everything else. But the UI part is just not my cup of tea.

    I build a basic UI and it looks like shut obviously.

    Which is when I feel demotivated.

    I was thinking if there is something already available i could just edit the bits according to my needs.

    I am dealing with material design mostly.

    Thank you.

    What type of backend would you use for this?

    Posted: 01 May 2020 07:37 AM PDT

    Hi r/androiddev, I'm looking to make my first mobile app. I'm researching server software backend solutions right now and am looking for some help.

    Here's how I envision the app working:

    1. The app will send data to a database on a server
    2. The server will perform intensive data analytics and ML logic on the data in the database
    3. The server will send data back to the app

    I have the data analytics and ML programming skills and the server setup skills. I'm versed in Python and C++ but could easily pick up any other language. I see myself either self hosting the server or renting a VPS. I'm looking for recommendations on what software platforms to use.

    My biggest question is: what is the simplest way to transfer data between a mobile app and a server? Ideally, it will be client agnostic - i.e. I could create iOS, web, or any other client app and use the same server for all the client apps.

    Also, what database software would you recommend? The database will basically be a relational deep learning dataset. Small batches of data points will be appended to the dataset at any given point in time and the whole dataset will be sifted through with certain data points extracted for ML model training at any given point in time.

    Thanks for helping out a noob!

    Whats's Going Wrong with This app??

    Posted: 01 May 2020 11:10 AM PDT

    Whats's Going Wrong with This app??

    I got 350K+ In last one month But this app is lots off alarming signals like

    First is, this game is not in the top categories in any country (categories means top games, top board games), But my other games are in top categories with fewer downloads

    Second is When I search My main keywords or keywords that are in App title I am unable to find this app in even top 100-200 results.

    The third is When I open this app in the browser, No similar apps will be shown.

    Fourth is I am running google ads campaigns for this app but all google ad campaign downloads showing under Third-party referrals in Acquisition reports.

    Have anyone of you faced similar situations ??

    Kotlin Multiplatform —Firebase + MVVM ��

    Posted: 01 May 2020 10:41 AM PDT

    Hi all, during this quarantine I have been working on a sample KMP project to show how integrate Kotlin Multiplatform with a Firestore DataBase (Firebase).

    If you want to see more about this project you can check this in Medium:

    https://proandroiddev.com/kotlin-multiplatform-firebase-mvvm-4cdcddd98893

    Or if you want to take action directly you can go to GitHub to see the code:

    https://github.com/jarroyoesp/KotlinMultiplatform_Firebase_MVVM

    I hope it helps you to understand a bit more about Kotlin Multiplatform. 😃

    Libraries used:

    - KTor: to make requests to an API

    - Serialization: to serialize objects

    - Moko-MVVM: Kotlin Multiplatform library that provides architecture components of Model-View-ViewModel

    -FirestoreKMP: Library wrapping the Firestore SDK for Kotlin Multiplatform with clients for Android and iOS.

    - KodeIn-DI: is a very simple and yet very useful dependency retrieval container.

    [Unit Testing] Mocking a static function in a final class using Mockito 2.

    Posted: 30 Apr 2020 09:19 PM PDT

    Hey everyone, I am trying to mock a static function within a final class. I tried mocking it's behavior using mockkatatic(), but getting errors as my test is failing for Androids under API 28.

    Apparently, mockkatatic is only supported from API 28 and above. Any workaround this one?

    More than 13 MTP devices connected at a time?

    Posted: 01 May 2020 10:17 AM PDT

    I'm attempting to connect multiple (48) Samsung tablets to a Win 7 laptop through three, 16-port hubs, but only 13 tablets will connect and register on the laptop at a time. Is there a limit for how many Portable Devices can be connected? I've checked that I'm running the lates Microsoft drivers (WpdMtpDr.dll, version: 6.1.7600.16385). The devices that don't mount do show in the Device Manager, but have the yellow triangle and give a "The device cannot start. (code 10)". Any ideas to get past the 13 max devices or is that a firm number?
