    Weekly "anything goes" thread!

    Posted: 13 Dec 2019 04:40 AM PST

    Here's your chance to talk about whatever!

    Although if you're thinking about getting feedback on an app, you should wait until tomorrow's App Feedback thread.

    Remember that while you can talk about any topic, being a jerk is still not allowed.

    Can I use affiliate links to products in my app?

    Posted: 13 Dec 2019 05:18 AM PST

    I have a fitness app and I was wondering if I could display my own custom ads instead of using Admob to show fitness related gear on Amazon like "Runners", "Treadmills" etc. Clicking on these would use an affiliated link.

    Admob earnings suddenly shoot up

    Posted: 13 Dec 2019 08:08 AM PST

    Today one of my app showed only 10 impressions of rewarded video ad and without any click I got $13. Any one ever had this kind of experience?

    Users reporting wiped data

    Posted: 13 Dec 2019 10:59 AM PST

    This morning I woke up to a series of emails from many different users who opened my app and discovered that their saved game files were deleted.

    Is there some new change rolling out across Android? Has anyone else encountered this type of issue all of a sudden with no app updates?

    Note that my game is built with HTML5 and uses localStorage to save game files and that's been working fine for years. I'm definitely going to migrate the data to a more robust storage mechanism now, but I'm just not sure what is going on.

    How to describe my responsibilities at my current work in my resume?

    Posted: 13 Dec 2019 09:45 AM PST

    I work as a fulltime android dev on a video streaming app. Mobile and TV android app. I am an only android developer at the team, so I do a full cycle. Bug fixing, adding features, communicating with client, with a current boss, managing Google and Amazon stores, monitoring crashes and bugs, doing code reviews.

    For novice developers, short list of websites to promote your apps and the reasons you should make apps with original source code

    Posted: 12 Dec 2019 07:44 PM PST

    As you well know it's extremely tough to get your game or app noticed. Here are some forums outside of reddit that you can post your apps. Make sure to read the rules before posting so you do not get filtered as SPAM. When I have time from my busy schedule, I will put together a marketing guide.

    I suggest you practice marketing on your own and not depend on Googleplay for traffic. Once the Index issue is solved, another issue might take place, not that I want that but it seems to be obvious . Thats why I highly encourage you to develop your apps with original source code.

    I do not agree with everything Google does despite some developers that may think so. I honestly hope that Google makes a complete stop to thier plans of banning repeat source code. I actually am against it because it has been tested and proven that sending bots to report and ban repeat source code does not fully work. The reason being is because frameworks or libraries for example any app made with LibGdx would be flagged and banned because of repeat code. That would be a nightmare for all indie developers. So I am 100% against that idea I feel it should be done manually.

    How to catch a java.io.FileNotFoundException exception thrown by W/MediaPlayer?

    Posted: 13 Dec 2019 02:48 PM PST

    I'm developing a personal streaming app and have everything built, I was planning on loading the videos on a third party website inside of a WebView however the videos never load. Inside the logcat i get the error thrown above however the resolved link contained in the log plays no problem in the browser on both phone and PC.

    Is there a way to get the link from the exception so that I can handle it directly?

    First freelance project - workflow advice

    Posted: 13 Dec 2019 06:04 AM PST

    So I have what would be my first freelance side project starting soon. I have never worked in a dev environment, so I could use some advice on what my workflow should look like. For those of you that have professional and/or freelance experience, what does your workflow/organizational process look like on a new project? Right now, I'm planning to use GitHub, Asana for tracking progress/tasks and Figma to sketch out the layout, which I will then send to the client for approval.

    [New Grad EU] Goals to break into the industry

    Posted: 13 Dec 2019 08:11 AM PST

    TL:DR;

    What should i aim for to get a job as recent grad in android dev ?

    I live in a decent Tech hub in the EU ~150 android and ~160 ios open positions averaged between (LinkedIn/indeed).

    Background

    • Finished college recently and i wanted to go into android when i started doing mobile in my 2nd last semester
    • After seen the requirements and a dozen rejections i figured i should focus on something i can start after college so i can start working
    • With new years coming soon i wanted to give it another try
    • I have a decent portfolio of web apps, IoT and Embedded programming projects
    • I found not much is expected from new grads so i figured id just focus on leetcodeing and do android if it works and i get in great if not ill go into web or something while i work my way towards android or ios

    Questions

    What do i need to know to get in ?

    Do i need to know things like Dagger 2, RxJava,Retrofit ? Every job posting i see asks for those.

    Should i upload all relevant android projects to my GitHub or is that not important ?

    I've had one engineer look at my GitHub for my interview and we ended up connecting on LinkedIn after (i took up another offer that ended up being bad long story, hence why i dont work with him now)

    Project/s

    Ive made a few clone apps, some basic apps in college calculator, web scraper etc

    The notable ones i have on my cv are:

    Arduino robot, controlled via android app and Bluetooth(BLE)

    Speed calculator, you can measure the speed at which you and the device is traveling, this data is displayed and graphed on screen (i made this app was to learn to use threads since data is graphed live and you can pause/resume the app)

    i wanted to make a another app and publish it on the play store just to have something that would look like a production app, would that be a good idea or should i just make smaller apps and keep learning android and the SDK that way ?

    --General req--

    Database

    Login

    Find free UI kits/assets and credit them ofc

    --User App--

    Track package by drivers phone location

    Reschedule delivery + maybe have a limit/restriction for this feature e.g cant reschedule when delivery is expected in 2 hours etc

    See when delivery should arrive aprox. Use google maps api ? maybe ?

    --Driver App--

    scan package, QR code reader etc

    take a picture of parcel when delivered for confirmation + maybe use location stamp for this also to prove where it was taken ?

    this is then sent to notify the user, use a notification for this

    Where is the eval javalike code function in Android or how could you build one?

    Posted: 13 Dec 2019 07:32 AM PST

    Similar to in a jvm you can use javassist to compile new classes at runtime and they are equally efficient as if compiled before jvm started.

    Help with 'signatures are inconsistent'

    Posted: 13 Dec 2019 06:18 AM PST

    Hello, everyone,

    Back in the day I developed an app. I would connect my phone to the desktop
    and click 'Run' button to test it. I would not have any configurations
    for signing and keystore defined. When building the app for release I would
    use a keystore that I set up for this particular application.

    Now I have a new laptop and installed Android Studio (newer version than I used previously)
    and I want to re-fresh the app by building it from scratch but using the same package
    and keystore, so that when I push an update, users wouldn't lose the data that's currently stored on the phone.
    However, when I try to test that the data is still there - when I click 'Run' AS tells me signatures
    are inconsistent and tells me to uninstall the app first (which will result in data loss).

    So, anyone has any idea on how I could make this work? Does AS use some default keystore/signature
    when clicking 'Run' and now that I'm on a different computer/project - it uses another default signature
    that does not match what my old one was installing the app with?

    Any help would be very appreciated.
    Thank You!

    Should you always default to using Constraint Layout?

    Posted: 12 Dec 2019 06:25 PM PST

    When is it right to use Constraint Layout and when are you better with just using another layout? I know that Constraint layout is best when there are a lot of nested views, but if the view hierarchy is flat are there any benefits? A lot of my coworkers just default to using constraint layout for everything without even giving it a second thought.

    Where to create Data Repository on MVP?

    Posted: 13 Dec 2019 12:21 AM PST

    Hi, I'm developing an app using both the MVP and the Repository patterns. I'm using Realm as an offline-first database and to initialize Realm I need to set the app context. For this I've created the Repository constructor that takes context as a parameter. Then I can just call a method inside the repository that initializes Realm.

    The problem I'm facing is this: If I create the repository in the view (main activity), am I not using model logic in the view? Otherwise, if I create the repository in the presenter, the presenter is being aware of the context, then I'm using view logic in the presenter.

    How am I supposed to bypass this?

    Error forcing me to use deprecated coroutine call adapter in latest app compared to previous app

    Posted: 12 Dec 2019 11:51 PM PST

    The first application is working well with coroutines, didn't have to add the coroutine core dependency, obviously no need for the deprecated coroutine call adapter. However, for the application I just made, it wouldn't recognize deferred without introducing the coroutine core dependency. Furthermore, it's giving me this strange error when trying to run my network call:

    java.lang.IllegalArgumentException: Unable to create call adapter for kotlinx.coroutines.Deferred<retrofit2.Response<com.example.catquotes.model.CatLink>>

    The calls worked after I added the call adapter dependency and added it to the retrofit builder. Afaik, the call adapter is deprecated so it shouldn't ever be needed. It gave this error without it.

    Here's the src code for the project that I'm doing where the issue of the coroutine dependencies is occurring: https://github.com/giancarlogatti/CatQuotes/tree/master/app/src/main/java/com/example/catquotes
