    App Rejected for missing Login Info, but we've provided it?

    Posted: 31 Oct 2020 10:20 AM PDT

    Hey there 👋! I've written a much longer post (see here about this at r/jellyfin) but I'll provide a summary here.

    We have an app that we've submitted with Android Auto for the first time. We got rejected for not providing login info. I filled in the Policy - App Content section about it and resubmitted. It's still getting rejected. Any ideas?

    Looking for a code review for a small todo-list app using Flows, Channels, DataStore, Hilt, Room, etc.

    Posted: 31 Oct 2020 04:00 AM PDT

    My focus in this small project was to get MVVM right and separate the logic between the fragment and the ViewModel properly. In the past, I've been writing a lot of logic in my fragments and I'm trying to learn how to do that better.

    I use Channels converted to Flow to emit events from my ViewModels for my fragments to listen to.

    Can someone take a look at this project and give some feedback? Any big mistakes?

    Best approach to generate Order ID for payment transactions.

    Posted: 31 Oct 2020 10:19 AM PDT

    Currently, I am using simple linear addition for generating new order IDs like 110000, 110001, 110002... But in this approach anyone can calculate number of orders placing on my app. So I want to add a new approach in which order ID is Readable but not Understandable by the user. I want to use this in my android app. So what can I do to achieve this using some logic or 3rd party libraries?

    Problem after calling alert dialog.builder

    Posted: 31 Oct 2020 08:40 AM PDT

    I use an alert dialogue to display an image on the screen. It's launched from a function that runs if a button is clicked. I'm not sure that I'm closing it correctly.

    My code is here. I suspect the problem may be from inside of loadPage(). I suck at logcat but I'm almost certain at one point it told me I had 12 screens or views. Also, it frequently tells me I have to call releaseView() or something after it crashes. Sometimes though, all it tells me is : E/eglCodecCommon: GoldfishAddressSpaceHostMemoryAllocator: ioctl_ping failed for device_type=5, ret=-1

    "Business Aspects" of Playstore as an independent developer ?

    Posted: 31 Oct 2020 06:55 AM PDT

    I develop apps on my own and wish to upload it. But there are a couple "business related questions" that isn't commonly addressed.

    I don't want to use my real name, can I just use whatever "business" name I want ? However that gave me a couple questions.

    1. Do I get full copyright to that organization name ?
    2. Do I have to register with any legal/government entities so that no one else can claim that name ?
    3. Any taxes involved ? If my app gets monetize.
    4. Home Address. Biggest privacy concern for me

    As much as it seems like I'm just some random dude creating simple apps, I want to treat it like a business so that if by any chance something goes viral or I turn it into an actual job, I would'nt be taken advantage of. If you guys have more advice feel free to add it in.

    Proto DataStore Android: Is It Worth It?

    NDK question #2, Kotlin or Java?

    Posted: 31 Oct 2020 08:39 AM PDT

    Thanks folks for the tips on the first NDK question, question #2:

    For various reasons (that probably aren't worth getting into here unless you into audio coding) I have significant domain logic code in C/C++. I understand now that using this in the NDK still requires making and understanding outer layers and OS interactions in standard Android and Java or Kotlin. Question: If this outer layer is being kept to a thin adapter layer around an inner engine in C++, does it make much difference whether I use Java or Kotlin? Any comments on the tradeoff for a use case like this would be great. I'll be mucking about with audio playback and timers/schedulers in addition to standard buttons and stuff. Kotlin looks nice, but maybe this layer will be so small it won't matter....

    thanks!

    How to fix app:DexBuilderDebug build failed error?

    Posted: 31 Oct 2020 04:24 AM PDT

    This is my second time building an app with android studio. I'm trying to build a currency conversion app that calls an API to do the conversion. However, when I run the app, I get the dexBuilderDebug error. I'm only getting this error after creating the interface and class for retrofit.

    I have my code and errors posted on stackoverflow . Has anyone ran into the same error before? How did you fix it? I can't even understand what is causing the error

    New android dev, what do I need to know to do C/C++?

    Posted: 30 Oct 2020 09:11 PM PDT

    Hi, I'm totally new to Android dev. I'm hoping someone can give me a brief roadmap on what I'm going to need to know to work effectively with Android Studio and C++ so I can start reading the right articles and so on. For example, do I need to know "normal" Java android-development for the NDK to make sense? Are there decent resources for learning C++ oriented Android dev that aren't out of date? Are all NDK apps hybrids where at some point I'm dealing with the JNI?

    I'm mucking about with JUCE but I'm a big believer in understanding what your framework is doing and not developing more married to the framework than need be, so I feel I should be educating myself outside of just JUCE oriented resources.

    EDIT to post, because people are (understably!) saying C++, WTF?? :-)

    I'm doing real time music and audio dsp, so C++ is the only game in town and I have significant amounts of code in C/C++/embedded Scheme for the apps on other platforms that I want to be able to re-use on android. I guess I should have clarified that, haha.

    Thanks!

    Personal or business gmail address for developer account

    Posted: 30 Oct 2020 08:44 PM PDT

    I plan on releasing a paid app to the play store soon. I don't really expect it to make me much more than beer money, so I'm not incorporating as an LLC or anything.

    I will be getting a separate gmail account though for the developer account. When I sign up for a new gmail address should it be a personal one since I'm just doing business as a sole proprietor (US based) or a business gmail account since I am selling something, which is a business transaction for the little it'll be worth?

    Mobile Developers Cafe Weekly Issue #12 ���� is out

    Posted: 30 Oct 2020 09:55 PM PDT

    So umm,... FragmentStateAdapter asks us to pass lifeCycle, and not only does it fail to unregister all ViewPagers/observers attached to it on the State.DESTROYED, but it also does not unregister the only thing it is meant to at least unregister which is the lifeCycleEventObserver its just created???

    Posted: 30 Oct 2020 06:22 PM PDT

    Is this for real??What TH I'm I missing here??At least the code to unregister the main LifeCycle we just passed "seems to be there" but the leak is still persisting...

    Are we still supposed to manually detach it from the RecyclerView....

    I don't know what to think about this...
