    Avatar Face Creation System

    Posted: 13 Jul 2020 04:22 AM PDT

    Hey guys, I have been creating a mobile game and I really wanted to have an avatar face creation/customization system in the game so players can each make their unique avatars. I've seen lots of apps recently that all use a very similar style of avatars (trivia royale as an example and they all look like memojis). I was wondering if they all made their own avatar system independently that just all happened to look pretty much the same, or is there some avatar face customization SDK or asset that all of these companies are using. As a quick follow up question, if I were to make my own avatar face customization system, how would i go about doing it? Thanks guys!

    What are your experiences with take-home-assignments before the interview?

    Posted: 13 Jul 2020 03:26 AM PDT

    Posting from a throwaway account.

    I recently got shortlisted at a Jakarta based startup. I have 5+ years of exp building a handful of successful apps for startups. I also have 2 side projects that are doing well. They shortlisted my profile and assigned a coding test - it was basically about building an offline-first app using MVVM and Kotlin. I properly architected the app, focused on every tiny detail and met every requirement to ensure it's high quality. A week after, they reverted with a positive response and scheduled a call. However, the person interviewing me is a CTO and did not talk anything about the submitted assignment, and held a 1 hour database-design-interview for an specific offline feature. I basically failed this round, because my hands-on experience with SQL is confined to trivial queries on Android. Not that it was super-hard, I just don't have the muscle memory for it to think quickly. Their job-description did not say anything about wanting good skills with SQL either.

    I was hoping the interviewer would be curious and ask questions regarding my approach in the assignment and so on. But none of that happened!

    Anyone had a similar experience? Is it expected that once coding assignment is cleared, the following rounds often have nothing to do with it? If yes, then what is the point of assigning coding tests in such a manner?

    Google play submission delayed since 25th June

    Posted: 12 Jul 2020 08:32 PM PDT

    Our app is on the store for 5 years now, we have had over dozen updates last year or so, our latest submission is being delayed since 25th June, no response other than we are prioritizing reviews for app (Which apparently isn't).
    Contacted google play via twitter DM, the only response is stay tuned, we are prioritizing reviews for app, thats it nothing else, ah and advising us to refrain from resubmitting the app so the cycle is not reset.

    Anyone else experiencing the same issues ? We are a B2B company, and our clients are already complaining (Promised bug fixes and paid features for them).

    Developer Name for App Publishing

    Posted: 13 Jul 2020 12:58 AM PDT

    Is it possible to choose the displayed developer name for an app(a name that is not the google account name)? I want to publish an app to the play store, and want to use my main google account, but I a worried that it will show as my name instead of my company name as the app maker in the listing.

    what is the alternative of setFragmentResult?

    Posted: 13 Jul 2020 03:40 AM PDT

    I am trying to communicate between fragments. On attach I set a reference to the parent Activity which is a FragmentActivity on child fragments. I tried to call parent.getSupportFragmentManager.setFragmentResult("key", bundleOf("k" to "v" )) but apparently setFragmentResult no longer exists under FragmentManager. Is there any alternative to this for message passing between fragments or am i supposed to pass callbacks all over the place through the main activity ?

    Please help, I need assistance to clarify confusion about the code below.

    Posted: 13 Jul 2020 01:48 AM PDT

    I am new to Android, I have been relying on the book "Head First Android" to learn it however, I ran through one of the book's scripts which is all about Fragments and this is where I faced this problem,
    it's been 3 days and I couldn't find any where else to post this issue, Sorry.
    here is the problem :

    in this class which extends a ListFragment we created an interface in purpose of getting a listener
    now we declared an object of that interface, later on as you well know "onAttach()" method runs after the activity's "onCreate()". Here is the confusion: inside the onAttach() implementation How was he able to cast interface's datatype onto the activity object ? What is the activity object what does it hold ?

    Please any one help this would mean quite a lot.

    package com.example.fragments; import android.content.Context; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.app.ListFragment; import android.widget.ArrayAdapter; import android.app.Activity; import android.widget.ListView; public class WorkoutListFragment extends ListFragment { static interface WorkoutListListener { void itemClicked(long id); }; private WorkoutListListener listener; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { String[] names = new String[Workout.workouts.length]; for (int i = 0; i < names.length; i++) { names[i] = Workout.workouts[i].getName(); } ArrayAdapter<String> adapter = new ArrayAdapter<String>( inflater.getContext(), android.R.layout.simple_list_item_1, names); setListAdapter(adapter); // this is how it gets populated. return super.onCreateView(inflater, container, savedInstanceState); //Calling the superclass onCreateView() method gives you the default layout for the ListFragment. } @Override public void onAttach(Activity activity) { super.onAttach(activity); this.listener = (WorkoutListListener)activity; } @Override public void onListItemClick(ListView l, View v, int position, long id) { if (listener != null) { listener.itemClicked(id); } } }

    Android Development newbie bombarded with options ��

    Posted: 12 Jul 2020 06:49 PM PDT

    Hey android devs, I'm a javascript developer and i want to get into android apps development too.

    But there are so many options of languages that I'm confused now. I can continue using javascript to make apps using react native but people say it's pain working with it, so i went to flutter but in a video one developer said that flutter has limitations and Native is better.

    Finally decided to go with native, but now comes kotlin and java. So should i learn java first? Or kotlin itself? Please suggest some learning resource too.

    Help to set the "Selected" state during the single click while Talkback is ON.

    Posted: 13 Jul 2020 12:46 AM PDT

    Hi devs,

    I have an app and was trying to identify how the content description is getting announced during the single click when Talkback is ON. The initialise() method is set with the content description "Tab Not Selected" for all the 4 tabs (custom tab views - Home, Calls, Calendar, More), hence whenever, the user performs a single click, the talkback announces "Tab Not Selected". The tab is ser "Selected" in the onClick() method. But the onClick() method is getting called during the double click, when talkback is ON. Hence, even though the user clicks on the tab (single click), Talkback announces "Not selected" which is not correct, as it will be confusing for visually impaired person. I need to handle the "selected" and "not selected" states of 4 Bottombar tabs (custom tab views - Home, Calls, Calendar, More).

    Would need help on how to handle the states "Selected" and "Not Selected" during the "Single Click". More importantly, in identifying, how the single click on the Tab is handled. Is this being handled by the accessibility service itself and the app doesnt have any control over it.

    What to learn for refreshment in 2020?

    Posted: 12 Jul 2020 03:55 PM PDT

    Hey Guys,

    Back in 2018 I started android development and learned the MVVM patterns + firebase. I developed some apps consuming public apis with retrofit. Soon I will be starting an Android internship and need to follow extra courses which I can select online in order to gain some extra semester points. So my question is, based on what companies expect from an Android developer, what frameworks and libraries related to Android in 2020 do I need to know? I already have 1 course planned for learning Kotlin and have two slots open for learning a new pattern/framework/library. The problem is there is not a clear overview and Im curious what current developers are working on and learning in the Android dev space.

    Tldr: what frameworks and libraries related to Android in 2020 do I need to know?

    Which Emulator do you use for PlayStore screenshots?

    Posted: 12 Jul 2020 02:37 PM PDT

    My Pixel 3a's dimensions doesn't work with the PlayStore's required. I'm wondering, which emulator will be best for phone screenshots? I don't want to have to use a third-party service or app to create these.
