    As an Android dev, selecting colors for my apps, building themes and making a (good) dark theme has always been hard. Even harder with MDC adding a white overlay in elevated surfaces. My newest app should help solve all these!

    We don't hear a lot of game developer's admob getting banned or suspended, whereas an app developers admob account is suspended in an instant . Does Google treat App developers unfairly?

    As a college student, should I pursue Android development considering it's difficult to get an entry level job?

    Posted: 25 Dec 2019 07:01 PM PST

    My understanding is that Android dev is a very difficult career field to enter without prior experience, and that companies don't hire entry-level programmers.

    I started teaching myself Android dev because (1) I have lots of Java experience (2) I've always been interested in Android. But I wouldn't say I'm loyal to Android development, and I didn't really learn much anyways besides doing half of the Udacity course.

    Should I switch over to another field like backend web-development to jump start my career if it really is that hard to find an entry-level job?

    Issue With Android Studio Emulator

    Posted: 26 Dec 2019 10:52 AM PST

    I apologize in advance if this isn't the correct place to ask about this, but I've been having an issue with the emulator on my Linux machine for some time now.

    I've noticed that on Linux, booting up and running an AVD writes an incredible amount to my SSD. Over the course of perhaps six hours (which is quite a bit), I can see that approximately 150 - 200 GB of data have been written to disk. When I ran Android Studio on Windows, I did not have this issue (only 10 - 20 GB were written to disk by all processes throughout the entire day), and I don't recall making any unique configuration changes on Linux. Is this normal, or have I done something wrong? I have had this issue persist across multiple installations.

    I'm sorry if I've omitted any important information, but I will be sure to provide it should it help. Thank you!

    Can I use a cheap carrier locked phone for android app development?

    Posted: 25 Dec 2019 09:19 PM PST

    I already own iPhone, but would like to develop an app for android. I was thinking of buying a cheap 1~2 years old android phone for app developments (no need for cell service), and about half of them in the market are locked to carriers.

    I am assuming I can still use Google Play & related services in carrier locked phones without SIM?

    Creating user accounts on an android app

    Posted: 26 Dec 2019 06:01 AM PST

    Hi guys, I would like to know how to create user accounts for an android application (user downloads the app and creates an account for himself). I have googled this but there aren't exactly many answers on this. (Here's what i found).

    Do I use something like firebase for account handling or do i launch an AWS server with MySQL installed to handle the accounts? Could you guys point me to any good tutorials on this? Thanks in advanced!

    Search bar that suggest words while you type, and after you click them, they are listed below bar so you can still remove them

    Posted: 26 Dec 2019 08:20 AM PST

    Hey, as its written in the title, I need search bar where you can add/remove keywords. For example (search bar for shoes): you type in "red" and click it (keyword red appers under search bar, search bar is empty), you type in two more keywords with same process (lets say "nike" and "43"). Then you decide that u want "adidas" instead, so click on "nike" will remove it from "soon to be" search call. I didnt rly know how can I explain all that, I hope you understand. I tried to find same search, and I found it on "Freelancer" mobile app, when you edit your profile and edit your skills. I will need this is android studio (Java) and for website as well (html,php).

    Thanks!!

    Requesting Contact Permission in simple app

    Posted: 26 Dec 2019 04:05 AM PST

    Hi,

    Android development is new to me, I am following this resource in order to learn how to add read contact permissions.

    Though I am not familiar with Java, code seems Okayish, till this point:

    @Override

    public void onRequestPermissionsResult

    Not sure if this article is outdated, but can't seem to understand why '@override' is required. When compiled it yields the following error:

    error: method does not override or implement a method from a supertype

    And when omitted, the permissions are not being initiated.

    ​

    Appreciate help in understanding this, as clearly I am missing something, TX.

    How do some apps show a dialog that allows you to choose your phone number?

    Posted: 26 Dec 2019 07:26 AM PST

    I've noticed that on some apps that require a login/registration by phone, it offers you the real phone number, so that instead of typing, you just select it via a dialog, then it gets filled on the app and continues.

    How do those apps do it?

    Is it a part of Android, or something that Google offers via one of its services/SDKs ?

    If it's a part of what Google offers, is it for free, or does it cost money to use it?

    Is APK Bundle safer than APK?

    Posted: 25 Dec 2019 06:11 PM PST

    Can we talk about APK here?

    So, I noticed that some app store sites provide APK Bundle. As far as I knew, APK Bundle is better than APK in term of app sizes, updating speed and other stuff. However, do you think that APK Bundle is safer than APK? Is there any way to know if an APK Bundle is modified or not?

    Thank you.

    Toggling the System Wide Dark Theme Programmatically

    Posted: 25 Dec 2019 08:41 PM PST

    Hey, everyone. I'm using a Pixel 3 right now and I was thinking of making an app that would allow me to schedule when the system wide dark theme would turn on/off during the day.

    I'm kind of thinking how Night Light, Night Shift, f.lux, etc. work. My quick reading about dark mode in the documentation is only coming up with information about an app's dark theme and nothing about potentially altering the system theme itself from the app/allowing the app to do it at a set time.

    Is this possible? Am I missing this part of the developer documentation? I'm not looking for a full blown tutorial or anything, I'm just struggling to find any reading about this from my Google searches.

    Thank you for taking the time to read the question! Also, sorry if this is the wrong subreddit to post this question, I haven't had any success with Stack Overflow the last couple of days.

    Where to find android development companies to invest in?

    Posted: 25 Dec 2019 09:22 PM PST

    Hey guys,
    A long dream of mine is to make an android game that I can be proud of, but I lack to commitment and mental capacity to learn coding from the bottom up, so I was wondering if I want to invest in a small start up android development company where I can find a team that will can bring my game idea/vision to life ? and how much do you think would that cost ? (I am not looking to just buy a whole company, just to invest enough that I can have a say on what is being made).
