    The Great 2021 /r/AndroidDev User Survey Android Dev

    The Great 2021 /r/AndroidDev User Survey Android Dev


    The Great 2021 /r/AndroidDev User Survey

    Posted: 02 Jan 2021 07:29 AM PST

    Hey all, happy new year!

    As discussed at the end of 2020, the 2nd step of the subreddit improvement plan is getting feedback from YOU, the actual users!

    I've created a survey to get your thoughts on every rule, as well as more general feedback. Every question is optional, but I'd really appreciate it if you could answer as many as possible.


    A few notes:

    • All responses are public, so don't reveal anything personal!
    • The survey will run for at least a couple of weeks, or until it receives a few hundred responses.
    • A summary post with conclusions will be posted a week or two after the survey closes.
    • The more responses the better, so feel free to pass it on to colleagues / friends.

    Here's the link, one more time:

    https://docs.google.com/forms/d/e/1FAIpQLSd-X4mnfHL0scPmHG4-6yXQYPYI9sMAAtQRu89sZYtLhXFVRA/viewform?usp=sf_link

    Thanks! :)

    PS: Looking for the usual app feedback thread or weekly hiring thread?

    Best Practices for Handling App Security with API Key

    Posted: 11 Jan 2021 10:59 AM PST

    Hey, all. I hope this doesn't fall under the "help me" category as I am looking for more of a general discussion on best practices. If it does, I will remove it.

    Anyway, I'm a web developer who may be working on an app for someone (I'm undecided on using Vue-Native/React-Native, NativeScript, or Ionic 5 if that has any bearing), and I was hoping to bounce a couple questions off of those who are more experienced:

    The app requires third-party API integration using an API key for authentication; am I correct that this API key shouldn't be available within the app's code? Assuming that's the case, would the preferred method to handle this be using a server-less function to store the API key via an environment variable and make the call there?

    Also, once I have authenticated the app, and eventually retrieved the user info, what would be the best way to store that the user has logged in? Is there a pretty standard TTL recommended for mobile apps?

    Anyway, sorry for all the random questions. If anyone is able to assist, it would be greatly appreciated and greatly help with planning the architecture. Thank you!

    [Library] Swipe to dismiss image layout

    Posted: 11 Jan 2021 02:55 AM PST

    I made a custom layout that will display images with features like swipe to dismiss, zooming, pinning, etc. See demo on Github.

    The idea is not unique but just wanted to learn how such gestures are implemented. The library is small & is under-development if you've any suggestion let me know :)

    Expandable lists in Jetpack Compose

    Posted: 11 Jan 2021 10:32 AM PST

    I feel so happy today. It's time to give back.

    Posted: 11 Jan 2021 11:39 AM PST

    I have been through times when I had tried to evade AWS just because it seemed too complex. I did not know the capabilities. A pure noob.

    But then I made a promise to delve into it for another time. And viola!!! I did learn a lot. I tried my hands at different tools and have a good grip over AWS now.

    I found many students struggling like I did and so I decided to break the myth and make a video and help them.They are new Android developers but did not know how to use Parse Server with AWS. So, I decided to give it a try and help them and others.

    I put it in a lot of effort for this video to be as simple as possible and tried my best. But again, I am new to this and hence will appreciate any feedback. I will be very happy if this video makes even one learner's life easy. I feel happy today.

    Thanks a ton all of you.

    My team is confused about the minimum API level (30 now?) to upload a app to the Google Play Store

    Posted: 11 Jan 2021 03:47 PM PST

    Does this mean only phones with this API level can play the game? My old Pixel Device can't play the latest version of our app at API 30, so pretty much they are forcing us to buy a new phone?

    Or am I misunderstanding something. Does API 30 have to be the target, but the minimum can be something much less?

    Thanks for the help.

    Question from a designer about using fonts in apps on multiple platforms.

    Posted: 11 Jan 2021 10:29 AM PST

    I am a designer creating a style guide and I'm not sure how to show the typography.

    Do different apps usually use a unique font that is the same across different platforms? (ie Helvetica on every device)

    Or would I just use the default font for each device (San Fransisco for iPhone, Product Sans on Google, etc)?

    Associate Android Develope rexam grading taking forever

    Posted: 11 Jan 2021 01:33 PM PST

    Hey guys, I have submitted my Associated Android Developer exam over 45 days ago and I still have not received any feedback from TrueAbility and even when I contact support I get no response.

    Should I be worried?

    They say that the grading process may take up to 45 days, which means I should have it graded by now, right?

    Is Kotlin/Django/Postgres a good stack choice?

    Posted: 11 Jan 2021 11:50 AM PST

    So I'm a physicist by trade, looking to build an app. I have some experience in R, Python, SQL and C, and have done some HTML/CSS for some static websites.

    I would like to build a data sciencey Android app this year, which will have some complicated backend requirements. I've learned a bit of Django but realised that it needs to be a native app. It looks like everybody's recommending Kotlin over Java these days.

    My question is, would Kotlin/Django/Postgres be a good choice for app development? My reasoning is:

    • Kotlin for speed of app development, plus cross compilable to iOS if needed later. Hopefully can pick up a bit of Java on the way. Also looks easier to learn than JavaScript
    • Django for scalable backend and ease of use, plus helps me to learn more Python for data science
    • Postgres is a solid choice for databases

    Do you guys have any recommendations?

    Thanks!!

    I have a Moto G4 I want to Repurpose as a Stand-alone Micro Tablet [Not a Phone] - Any Tips or Tricks?

    Posted: 11 Jan 2021 09:19 AM PST

    Hey guys,

    I have a Moto G4 sitting in a Drawer that hasn't been used in a few years. I have a few Sporting Apps I'd like to install on it and treat is as a Micro Streaming Tablet and leave the Phone part redundant.

    Handy little device f I can get it working nicely.

    I'm in lockdown so could be a nice little product.

    I can just side load the apps on the device but would be nice if I could possibly install a CustomOS that works with Google Play etc and get it working more as a tablet.

    Anyway, any ideas guys?

    If I have an Activity with multiple Fragments on Screen, how do I refactor it for Android Jetpack?

    Posted: 11 Jan 2021 08:21 AM PST

    I have an Activity that has three Fragments on Screen to compartmentalize different features of the Layout.

    I'm considering migrating to Android Jetpack Navigation but Jetpack Navigation seems to be about one Fragment for every screen. How would I refactor the Fragments in this scenario to make them work with Jetpack Navigation?

    In-App Purchase refunds

    Posted: 11 Jan 2021 07:38 AM PST

    Hello all,

    I recently introduced an in-app purchase on my app.

    However, it appears that users are abusing the refund feature by making an in-app purchase and requesting a refund immediately thereby getting the benefits of the in-app purchase without paying for it (despite the purchase costing barely anything).

    Is there a way to circumvent or prevent this? Because of this, I am seriously considering removing the in-app purchase product from the app.
