    Selling In-App Products With Dynamic Prices

    Selling In-App Products With Dynamic Prices

    Hi, I joined a team that is selling products from a third party. We can use an example of shoes. However, the price of each shoe is generated dynamically based on parameters the third party sets. The third party has an end-point that gives us the price of each item. The back-end gets this price, adds other details to it and a user can pay via PayPal on the web-app.

    Now, we need to implement buying in the mobile app. The mobile app queries the details from the back-end via the same end-point that's used on the web-app. The issue though is that the price is dynamic and when a user has to pay via in-app billing, the product must exist in the Play Console. Our current idea is as shown below:

    Purchase Flow

    When a user adds an item to their cart, the back-end creates that same item in Google Play with the exact SKU. The user can then pay via Google in-app billing and then we go through the purchase verification process. There are a lot of issues with this and it feels hacky.

    The back-end devs have been looking at the Play Billing API and Real-time Notifications and they cannot find a way in which there are web-hooks that would make Google check for prices from our server in real time before a user buys. Is there a better way to do this or something we are missing with the Google Play APIs?

    Posted: 30 Sep 2021 08:35 AM PDT

    Hey guys,

    What do you think about the new 30 characters in title limitation? Have you changed your titles already? If yes, how has it impacted?

    "Your rating in some key regions is likely to change"

    Posted: 29 Sep 2021 10:54 PM PDT

    Android Developers Blog: Making Ratings and Reviews better for users and developers (googleblog.com)

    My app is fairly small (100k downloads). This means that my rating in many regions will be based on only one single review, and will be either 5 stars or 1 star.

    How is that more helpful?

    how to bypass an apps ability to know is being run on an emulator rather then a real device?

    Posted: 30 Sep 2021 11:02 AM PDT

    Hy, is there a way to bypass the detection of emulators of apps, the app should be 100% sure that it is a real phone.

    I can't make any changes to the app itself.

    It is very important for me, am happy with any solution!

    Also, it should still be functional and I should be able to have multiple emulators open at the same time.

    Thanks for your answers!

    Requesting best practices to remove lag on Jetpack compose Sectioned LazyColumn

    Posted: 30 Sep 2021 01:15 AM PDT

    Requesting best practices to remove lag on Jetpack compose Sectioned LazyColumn

    Hi there, I am developing a sectioned LazyColumn in Jetpack compose similar to that of the contacts list. The list items can be removed and added dynamically. And even there is selection and un selection of whole sections or part of the sections. Right now, the sectioned LazyColumn is too laggy. For sectioned LazyColumn implementation, I simply followed the instructions provided on the video out here ( https://developer.android.com/jetpack/compose/lists). So my main data source is

    Map<String,List<Contact>> contacts LazyColumn{ contacts.forEach { key,contactList -> item{ Text("Header Information) } items(contactList){ contact -> Text("Some contact info") } } }

    I have tried running the app on the release version as suggested by this reddit post but couldn't see any improvement in the performance.

    Greatly appreciate if someone can point me in the right direction for a use case like this. Thank you.

    What is current best tech stack for modern apps?

    Posted: 29 Sep 2021 11:54 PM PDT

    I want to create a new big app like a movie browser or a marketplace, basically lots of screens, complicated navigation but nothing non-standart, what's my options? After a brief research it looks like this: MVVM with LiveData and coroutines, single activity with fragments + compose? I also saw MVI but is it really good alternative? Is it ok to not use RxJava at all?

    MediaCodec+Camera2

    Posted: 30 Sep 2021 01:34 PM PDT

    Let me start with a rant: I am a senior Android developer, with quiet a few years of experience. I started working in a new company and here I need to use MediaCodec. I am really surprised to see how bad the documentation of that part. It is really overwhelming how bad it is. I can't state it enough. I am trying to see if someone implemented a demo that reminds this way or another the documentation. Nada. Zero. Nil. I found out that there are mostly examples of tests (wtf) that were made by one guy, that worked at google. I guess he probably the same guy that wrote the documentation and the Camera2. So my question is, can someone explain me the big picture of the pipeline of how to capture a video from the camera and encode it to mp4 while using a surface? What is the use of a surface? Do I have to use OpenGL? Thanks.

    Using Jetpack Compose in production

    Posted: 30 Sep 2021 01:29 PM PDT

    Anyone using Jetpack Compose in production?

    How trustworthy is the API and is it prone to change? Do you feel any improvement in the project in comparison to XML layout?!

    Looking for tools to monitor services

    Posted: 30 Sep 2021 05:48 AM PDT

    Hi guys,

    i am working as a tester in the automotive field and we are also working on an app.

    Now as i have no experience with app testing, i wanted to ask here first.

    How do you test apps? How can you monitor the availability of services 24/7? Is there a way to specify that action x should lead to information xyz being shown on the screen and if that isnt the case, raise me an alert?

    Upgraded to Arctic Fox 2020.3.1 and my "src/main/jni" is not showing in the project anymore.

    Posted: 30 Sep 2021 11:51 AM PDT

    I updated AS and now my native files in "src/main/jni" are not shown in the project.

    I build the files externally but I want the whole 'jni' folder to be visible in the project as I use AS for editing and searching the files.

    Do you know how I make them visible again? Maybe a method to make any folder visible in the project?

    Compose: Put a specific offset value for a modifier only in the initial composition

    Posted: 30 Sep 2021 05:47 AM PDT

    https://reddit.com/link/pyj2du/video/3nyqhtsvzmq71/player

    I want to implement "Swipe to show buttons" feature to my card as the following:

    -- Box

    -- Card

    -- Row(here I put the buttons which showing when swiping the card)

    Now the card and row are visible next to each other so I want to offset the row to be invisible in the normal look and return it to 0 offsets(visible) when the user swipes the card.

    when observing the user's swipe on the card I do the following:

    • Change the card's offset based on the Row's width to the left via animateFloat like this:

    ​

    val offsetTransitionCard by transition.animateFloat( targetValueByState = { if (isRevealed) -rowWidth else 0f }, )
    • Change the row's offset to 0 via animateFloat like this:

    ​

    val offsetTransitionRow by transitionActions.animateFloat( targetValueByState = { if (isRevealed) 0f else rowWidth } )

    till now all good but we have one problem when the initial composition occurred the rowWidth will be 0 because it's not calculated yet which means the Row offset will be 0 too which means again the Row will be showing for mills then will offset when the rowWidth gets ready.

    So I want a way to make the row's default offset to be like 500 instead of 0 on the initial compose only.

    How to stream video from a medical device to my server

    Posted: 30 Sep 2021 08:28 AM PDT

    Hi there :)

    I have a medical prob that connects to an android tablet and displays video imaging in a dedicated app.

    My goal is to be able to stream the video from the app in realtime to my server and then run an AI algorithm on it.

    Alternatively, I could save the video and then upload it (after the X seconds of latency) to my server.

    Can you recommend a method?

    Thank you!!

    Different functionality in Android Studio (Bumblebee) than using ADB via command line

    Posted: 30 Sep 2021 07:54 AM PDT

    Hi guys. I'd really appreciate any insight into this at all. I've done so much investigation but haven't been able to figure this out.

    So I'm using Android 11 Wireless Debugging. On my target PC, using Android Studio I am able to pair ADB wirelessly to my phone and it instantly connects, will reconnect if I flick off and on Wireless Debugging and I can use it fully. However using the adb.exe via command line for platform tools (both the ones used by Bumblebee/30.0 and the newest available for DL 30.3) the device is able to pair, but will never automatically connect to the machine. I am able to manually connect via adb connect ip:port, however this is not viable for my project.

    Now on multiple dev laptops I am able to reach the functionality required with command line. Can anyone (really am begging now haha) think of any reason I would be getting this functionality in Android Studio and not when using the platform tools directly?

    Really appreciate you guys taking time to help me.

    build folder gets generated multiple times

    Posted: 30 Sep 2021 02:37 AM PDT

    I'm facing this issue in one project for a while now and haven't found a solution why it's happening. The error message is in the screenshot. After Clean Project and Rebuild, my app runs but after some time this issue happens again for a separate file. multiple build folders get generated. build.gradle files are in the link.
