    Android Dev - QUESTION: Taking too long to get results of Google Android Associate developer test

    QUESTION: Taking too long to get results of Google Android Associate developer test

    Posted: 08 Oct 2020 01:03 AM PDT

    Hello Everyone,

    I completed my Google Android Associate Developer assessment and exit Interview on the 15th of May 2020, and my assessment as been being graded since then, its about 5months now. I have reached out to Google support but they have not provided any actual solutions or reasons.
    Is this a reasonable amount of time for the results to still be processing even with Covid-19 restrictions, can anyone with more information help me out.

    Thank you

    Anyone come up with a good solution to lagging fragment animations?

    Posted: 08 Oct 2020 08:24 AM PDT

    Hi there. I guess every single Android developer has had this issue sooner or later, concerning fragment animation or transitions that lag or get skipped completely do to various reasons.
    Most notably, these occur when you are starting a server call right when you create the fragment, the call is very quick, and the data gets rendered in RecyclerView adapter faster than the animation. The animation which gets executed on UI thread will be stutter because of the ViewHolder inflation which also takes place on the UI thread.

    What's worse is the even without the inflation of ViewHolders, fragments still seem to never actually have a perfectly smooth animation. Every developer I have talked with suggested me that he simply ignores the issue, but it's not the case for me, I want my app to be perfectly smooth. This is a major downside for Android, since iOS does not seem to have it. iOS always had very fluid and smooth 60fps animations.

    At this point, I don't even know what to do. I almost want to ditch using fragments because activities seem to have different behavior and better animations, but then get architecture issues and I still have to use fragments. Ended up delaying the server calls until the animation finishes (400ms) but unfortunately the delay is visible.

    Anybody that found an actual good workaround this, to achieve perfectly smooth animations?

    Collate all categories in SQLite database for "All questions"

    Posted: 08 Oct 2020 02:37 AM PDT

    Hello all,

    I recently threw myself into the deep end and set out to develop an android app with very little experience in coding. I've followed advice given in this subreddit on my previous post and have been following a YouTube series by Coding in flow as this is exactly what I'm looking to do and feel like I'm learning a lot. I have adapted the code for my needs but is mostly the same (can be seen in his description box).

    I'm struggling to get my head around the following: how do I make an "ALL" section which collates all questions, regardless of category. I have a feeling I'm overthinking this and would appreciate any input.

    On a unrelated note, I've used his code for the spinner and it seems offset to the right despite being aligned to the start of the START QUIZ button. Any ideas?

    I'm not really sure where to post these kind of basic questions. I unfortunately don't know anyone in the field who could help me out. I tried at stack overflow in code review but my post got removed.

    Thanks!

    Is it possible to load more items from a listing API before reaching the bottom of the list?

    Posted: 08 Oct 2020 12:53 AM PDT

    Hello!

    I am building an app that uses Paging 3 and a REST API through Retrofit, to fetch items. I have a recyclerview and I want to load more items and add them to the list before the user reaches the bottom. I'm also using LiveData and a combination of Kotlin/Java but I don't think it really matters.

    Any help would be greatly appreciated, Thanks.

    What virtual devices test on?

    Posted: 08 Oct 2020 09:36 AM PDT

    I'm not sure if this constitutes as "help me" in the sense that the rules outline, but I'm not in the Android world at all, whether it's the phones or the version is the latest. And I don't know what online resources are available.

    Anyway, if anyone has a link or can tell me what devices/device specs are "common", and versions of Android that I should test on, that'd be great!

    How to disable blue highlight/edit box around EditText?

    How to disable blue highlight/edit box around EditText?

    Is there a way of disabling this blue box when the keyboard is gone (following a back press or apply)? My searches aren't showing anything useful at all and I'm not sure what the box is even called. My problem is that I cant get rid of it unless I click on another item. I am using a recyclerView with a layout of edit texts.

    Ideally I'd like to turn it off after action X so it disappears and then immediately turn it on again.

    Difference between running unit tests on command line vs in Android Studio?

    Posted: 08 Oct 2020 07:15 AM PDT

    What is the difference between running tests using "gradlew testDebugUnitTests" and running unit tests from Android Studio? Why might my tests pass on command line but get a bunch of "ClassDefNotFound" errors in Android studio for Mockito?

    Worth nagging users for a review?

    Posted: 07 Oct 2020 03:28 PM PDT

    I think it's a bad user experience to ask a user to rate the app or show an in-app rating. We interrupt the user and then ask for a favor.

    Wanted to find out if that was just my personal opinion. Ran a small survey and Android users agree it is annoying... but users also said they wouldn't give a rating otherwise.

    How do you balance the need for reviews without irritating users?

    Has anything you've tried backfired?

    Getting a level deeper in Android, Becoming a Tools developer

    Posted: 07 Oct 2020 10:37 AM PDT

    Hi everyone,

    There are lots of great tools and stuff which are open-source and we android developers use them on a daily basis,

    We have Dagger, Retrofit, Kotlin Language, Coroutines, Some of Jetpack libs, and many other open-sourced technologies that are being developed targeting Android. So as a developer who mainly uses these tools and builds applications using them what are the things that I/we should know or learn in order to be able to understand the problems that these tools deal with and be able to solve them and contribute to them?

    Seeing all these tools and new features that come every day( wether as first-party or third-party tools) really fascinates me and I'm looking for a way to be able to dive deeper into these topics and how they are being developed.

    What are the specific topics that we should learn about? Jdk internals? Are there any books or any roadmap to follow?

    I truly appreciate all your advice.

    Consume REST API from Kotlin?

    Posted: 08 Oct 2020 04:08 AM PDT

    Hi all,

    No matter what method I try (googling like a demon), I cannot get this to work.

    Nearly every single example I have found online doesn't compile - and the couple that do, simply don't work, or crash the app out with no error the moment I attempt to connect.

    Someone here must know the easiest way to make a simple GET request to a third-party API and iterate through the JSON result?

    I'm starting to wonder if it's possible - despite, I should think, nearly every app out there needing to do something similar.

    So far, this is the closest I've got:

    override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val text = "Hello toast!" val duration = Toast.LENGTH_SHORT val toast = Toast.makeText(applicationContext, text, duration) toast.show() val button = findViewById<Button>(R.id.button) button?.setOnClickListener() { Toast.makeText( this@MainActivity, "hello again", Toast.LENGTH_LONG ).show() sentGet() } } private fun sentGet() { val url = URL("http://www.google.com/") with(url.openConnection() as HttpURLConnection) { requestMethod = "GET" // optional default is GET println("\nSent 'GET' request to URL : $url; Response Code : $responseCode") } }

    But when I click the button, the app simply disappears without a word.

    I am a newbie, just wondering if i can have an app's database in device and keep accessing it.

    I am not sure if it is possible.

    1. what are the chances of data loss and under what cases i may lose data?
    2. how to do this...like what should i use for doing this?

    Some helpful resources for this will be really appreciated.

    Building an app for Gingerbread device in 2020

    Posted: 07 Oct 2020 01:20 PM PDT

    I have an Android Device, Samsung Galaxy Y. It runs Gingerbread. That's all it will ever run, it can't be upgraded due to being Arm v6 and 256mb ram. The battery is new, and everything works, however. I want to use this phone for something, maybe as a webcam, IOT remote, or something else.

    So I wrote a blog post detailing how I got an app installed using Android Studio. Something I've been meaning to look at for a while:

    https://www.circusscientist.com/2020/10/07/creating-an-app-for-android-gingerbread-in-2020/

    Does anyone else care about old devices here? My S2 is nearly 10 years old now, and runs Pi just fine. It will be getting Android 10 soon.

    App to call third-part REST api, for C# dev

    Posted: 07 Oct 2020 01:40 PM PDT

    Hi all.

    I've been trying to make a simple app that calls a third party REST api to pull data down, then have that manipulated by the user then sent back to an API on my server of my making.

    I'm a C# dev, so knocked up a prototype in dot net in about 10 minutes.

    Then I started to read about Android development.

    Jeeeeees! There seems to be a metric #$@& tonne of choices.

    I chose "Cordova", but after several hours of installing bug ridden things like JDK (which wouldn't even download in Chrome - had to use Firefox just to get it to download), installing into file paths that don't exist etc..., then the Android Studio cmd line tools, that wouldn't run etc...I finally gave up, exhausted.

    Which is the simplest way for a dev, coming from a background of "run the installer, and it will install" C# dev to write this app?

    React native looked to be reasonably simple, but could be overkill due to not needing a cross platform app.

    Cordova drove me around the twist, and Xamarin is so buggy, it's not worth the heartache and high blood pressure even trying it.

    So, what would someone who knows about these things suggest for me?

    I'm more than happy using Linux if the tools are more mature.

    TIA.

    EDIT:

    I cannot get one single example to work. If I copy a small chunk of code from a tutorial, I get dozens of errors. Even really simple "click a button and have 'toast' pop up' don't work (although that did compile).

    EDIT 2:

    Tried Xamarin (again). It hasn't got much better. It feels a little more stable than it used to, but I can't get anything deployed to an emulator or device after build. It's making all the right noises, but never actually spawns something where I can see the app.

    I'm starting to feel like I'm in a parallel universe, where apps for Android simply appear with nobody having developed them. I've tried for years to develop an app for Android with no success. I used to write games in pure assembler, then progressed through to 32Bit ASM when Windows came of age. I used to develop in Smalltalk, Forth, then C/C++, then VB through to C#. No problem.

    Every 6-12 months, I seemingly forget the pain and have another stab at Android development using whichever tool is the current favourite at that time - and then fail miserably.

    I cannot ever seem to be able to do the same in any language made to develop for Android.

    GAEN working

    Posted: 07 Oct 2020 01:03 PM PDT

    I was wonderinghow the GAEN exposure API works ? Does it employ bluetooth, hotspot tethering ?
    Does the GAEN opperation keep the phone's bluetooth on all the time ? Are their better ways to race phones by using the Nearby Google API ?
