    MVVM Adapter Data source

    Posted: 21 Nov 2020 03:54 AM PST

    Hi everyone!

    I think there is no more doubt about where adapter should be in MVVM architecture - it's View layer. But I've faced problem that I need to connect it with data source (mostly ArrayList of items) and the selected ones of them, which are placed in ViewModel. I failed to find some complete solution for that, so I made my own, which I'd love to share with you.

    https://github.com/Ircover/LiveSource - LiveData like solution to place it in your ViewModel. It holds both ArrayList of items and information about which of them are selected.

    https://github.com/Ircover/SelectingAdapter - solution for adapters. It contains BaseSelectingListAdapter class for quick adapter creating, and extension functions to connect adapter with LiveData from previous link.

    And if you are interested, here are articles on Russian about developing it: https://habr.com/ru/post/483552/

    AmplifyException - UsernameExistsException (Android)

    Posted: 21 Nov 2020 05:08 AM PST

    This question is mainly about Android Development with Java and AWS (Amazon Web Services) Amplify Auth.

    I have an Amplify.Auth.SignUp method with me which signs up the user and if the user already exists, it throws an error toast at you and logs the error in Logcat.

    Amplify.Auth.Signup code: I have given the code in the Image & Video part.

    If the user is not there in the user pool, I have some code to display. I don't know where to place the code which will get executed if the user is not found in the user pool.

    And, one more thing, how to delete a user from the user pool in java, android? I searched everywhere but there is no Amplify.Auth.DeleteUser method.

    Can someone please help me with this? Thanks in advance.

    Help about custom loading animation

    Posted: 21 Nov 2020 08:10 AM PST

    Hello everyone,

    ​

    I'm looking to create a custom loading animation, but I can't find what I'm looking for. For the moment I have created something using AnimationDrawable and an xml file that contains all the images to display. The problem is that it's not nice at all since it's jerky and not fluid. I would like something more fluid, do you have any advice ? If so I'll take it.

    ​

    Thank you

    In receycler view if we populate the json response

    • data1
    • data2
    • data3
    • data4

    But I want to program my list view so that based on the json i have i can also group those data in my view

    Group1:

    • Data 1
    • Data 2

    Group 2:

    • Data 3
    • Data 4

    How do I go about achieving this in my recycler view.

    How can I programmatically add group 1 and group2 text view in my recycler view based on the types of data.

    About to finish my first app. While it works, I feel like I've made some bad mistakes during development, would like some advice

    Posted: 21 Nov 2020 04:03 AM PST

    Hi guys. 6 months ago I started working on an Android app and it's now almost done. The app doesn't store any data on the device, and it uses an API for fetching data whenever the user interacts with it. While the main functionality works, I keep having some problems which make me think that I've made bad mistakes during development. For example:

    • I use a bottom menu, and sometimes when I switch between the pages in that menu, the app crashes
    • I use multiple activities based on the screen / functionality that I want to present, and sometimes when I press the back button the app either crashes or keeps going back to previous activities / screens forever
    • I use tab views, and sometimes when I swipe between tabs, their content disappears and I have to close and reopen the screen I was on, to get the content back on it again

    I think the root cause of all these issues is the fact that I implemented a big part of the app based on answers I found on StackOverflow, because I can't find proper tutorials or guides on android best practices.

    Before launch, I'd like to spend some time on refactoring and making sure that I eliminate all the above bugs. Can you recommend books/tutorials/guides that go beyond the "hello world" and "how to display a button" kind of stuff? I'm mostly interested in architecture, how to properly use the components, how to structure the code, how to avoid the kind of issues that I mentioned above and so on. Thank you!

    How to google sign in in a webview?

    Posted: 20 Nov 2020 09:51 PM PST

    I have a website which requires google sign in. I put this url in a webview, the sign in option is available but after I enter my account details, it doesn't move forward and keeps on loading. I've tried to find the solution online, but couldn't find anything relevant. Is this a problem with webview. If yes, is there any alternative?

    PAC causes all Google play services to stop working?

    Posted: 20 Nov 2020 10:24 PM PST

    I'm getting this problem that on my Pixel 4a Android 11 RP1A.201105.002. But this repros before that. It seems that all play services and LinkedIn ( somehow this is also affected ) are affected but not most other apps such as Lyft, chrome and firefox. I tested with a simple return 'DIRECT' PAC file and tried to put it in https endpoint but nothing works...

    What is preferred way to learn RxJava in 2020?

    Posted: 20 Nov 2020 12:48 PM PST

    I have a company I am interviewing with who is still using mainly Java/RxJava. While I have been using Kotlin and coroutines for the last few months, I need to backtrack and refresh my memory.

    • Are there any good write ups or videos you guys would point a new Rx developer to?
    • What aspect of rxjava should get the most focus?
