    Android MVVM example app - Kotlin Flow + Dagger Hilt + Retrofit + StateFlow + MotionLayout

    Posted: 30 Nov 2020 07:13 AM PST

    Hi!

    I have refactored my previous app, and now it uses the newest libraries and recommendations from Google.

    You can find the source code for this sample application on my GitHub page https://github.com/inspire-coding/OMD...

    This is a sample application, which uses the OMDb API to get movie data.

    The app follow the MVVM software architectural pattern and uses the below libraries.

    📱 Kotlin Coroutines

    📱 Kotlin Flow

    📱 StateFlow

    📱 Dagger Hilt

    📱 Retrofit

    📱 Gson

    📱 Navigation Component

    The app contains shared elements animation and a collapsing toolbar effect which was implemented with MotionLayout.

    Using MotionLayout the search field goes up at the first search and stays there because of StateFlow.

    Selling An Android App

    Posted: 30 Nov 2020 11:19 AM PST

    Hey guys!

    Recently I've got an email from Appholdings, telling me that they want to buy my app.

    They have asked me to provide screenshots of daily downloads, ad revenue and stuff like that, after that I got an offer (not satisfactory but I will negotiate). If'll get the offer I want I might want to sell.

    The guy I was talking with explained the acquisition process and it looks like this

    On the process end, once we agree on the terms, we will sign a contract and then I will deposit the money into Escrow. After that, you transfer the items, we'll check them over on this end, and the Escrow agent releases the money to you. The entire process usually takes no more than a week.

    However I'm still a bit afraid that it's just a scam.

    I might be overthinking it a bit but the emails with that company were not as official as I would expect from a developer that has so many apps.

    So my question is whether anyone here has experience with selling an app or with this company?

    If someone could share some thoughts that would be great!

    Is there any way to develop/write android applications on an iPad? Not run them only write, like an IDE or online.

    Posted: 30 Nov 2020 12:55 PM PST

    I want to attempt my first side project, but I’m unsure if this is unrealistic for a total beginner.

    Posted: 30 Nov 2020 12:37 PM PST

    Hi! I want to attempt to fully customize an Android device. Tbh I have very little programming experience beyond front end dev and some simple PHP.

    For me personally, a few months of tinkering on a challenging project seems to be more rewarding than a few months of programming tutorials.

    Basically I want a device just for maps and music, ideally with the ability to: 1. Pair with other devices with Bluetooth 2. Store Google Maps areas for offline navigating 3. Store Spotify playlists for offline streaming 4. Connect to LTE network

    I'm fine with paying a monthly fee for LTE service.

    Since I can already do all of this stuff with existing Android apps, all I have to do is remove a bunch of functions and customize the home screen, right?

    A few things I want to do: - remove all apps except Settings, Spotify, Google Maps, and the ability to dial emergency services - customize the boot up/shut down animations - maybe customize the appearance of the home screen and settings panel

    I seem to learn best when I have a clear goal in mind and do tutorials/courses as needed rather than doing a bunch of courses just to learn. Plus it's just a lot more enjoyable and interesting.

    Do you think this is something I can just sorta learn as I go? Or am I totally underestimating the complexity and difficulty of something like this? Any suggestions for a total noob?

    Also, let's say I jump in and realize I'm in way over my head. Are there software consultants who would not only provide a solution but also explain their approach? I'd be willing to pay an hourly rate for consulting if it could teach me something new... it would bring my ideas to fruition and teach me valuable skills, at a fraction of the cost of CS courses.

    Thank you in advance for reading this and taking time out of your day to help a total noob 🙏 Appreciate it.

    Testing Never-Ending Flows

    Which mocking library are you using?

    Posted: 30 Nov 2020 01:05 AM PST

    I'm working on a large Android project which I'm slowly migrating from java to Kotlin. At the moment I'm using com.nhaarman.mockitokotlin2 but it doesn't support mocking final classes which I need as I'm spying on `object : Foo() {}` final classes.

    What are the recommended mocking libraries in 2020 when using Kotlin?

    Booking App using Android Studios and SQLite

    Posted: 30 Nov 2020 04:18 AM PST

    Hi guys, just a quick question. For a project in college I decided I'd do a booking app in android studios and the database would be SQLite. Im not the best programmer, in fact you could say I'm pretty crap. Is this idea even possible? I can't find many resources online that can help me. Thanks in advance!

    A small question about monetization regarding ads.

    Posted: 29 Nov 2020 09:26 PM PST

    Didn't know what key words to use, so I might as well ask here.

    So I'm in a game development group and I'm the odd one out that usually solo develops my own projects. I believe my group is fine with me adding my own game to the group app store page.

    To my knowledge, I can sign up to admob and get a token that allows me to play ads in my app and have the money go to my account.

    I want to know if it is allowed to post a game to a separate account while having a token for a different account.

    Purple Buttons

    Posted: 29 Nov 2020 06:42 PM PST

    Ive recently started coding on android studio and have very limited knowledge of XML. I was wondering why the process of changing colours of buttons isn't straightforward(android:background="" isn't working) (default set to purple). I looked at the answers on stack overflow and all the simple ones don't work.

    Note to Moderators: I've gone through the rules and it said "help me" questions are banned and i would like to clarify that im gonna ask my "how to" question on the thread provided. Im posting this question up here to learn why this is so.

    Also Thanks:)

    Edit:TL;DR

    I got my doubts clarified, thanks a lot to all those who up voted and commented! My questions on stackoverflow have been banned and had been subject to intense scrutiny when i started learning programming a couple years ago as i didn't have the knowledge of the base concepts n didn't understand when they used big terms. So i really appreciate even the few upvotes and replies i got as im a newbie at xml today like i was a couple years ago in java as its really encouraging.

    Iceraven Android Browser is Looking for Volunteer Developers

    Posted: 30 Nov 2020 12:44 AM PST

    I am not the owner of Iceraven and it is not a for profit venture.

    However, it lets me do and see things no other browser out there lets me do and see on Android (At least not all in one browser), so I've been part of the user community since it began.

    The idea is allow as much customization and as many user options as possible- in as visible and easy to understand manner as possible. Other browsers cut back on that kind of thing while Iceraven dives in.

    It is a fork of Firefox for Android that integrates all the good stuff from Firefox's stable builds and offers Firefox extensions, but also does stuff like have an option to turn on protocol (http://, https://) and "www" where applicable (Which Firefox strips from URLs), have a completely different tab interface with squares on their own page instead of only having an overlay with skinny rectangles (or use the other interface- you decide), allows people to load many more extensions than Firefox, makes about:config available, strips out all the proprietary telemetry, has a more useful "home" area with more icons, etc..

    It also attempts to give the end user more information about the browser and what it is doing and not doing, and information about the pages visited.

    Here is the problem:

    There was in theory a three person team of maintainers. However, it's a volunteer thing and they all had day jobs. One guy went totally AWOL, no one has seen or heard from him in a long time. Another guy quit recently, declaring he did not have time and that he prefers to just use Firefox.

    That leaves just the founder/lead developer left, and, to be honest, we weren't even sure he was still there until conversations about how to carry the browser forward in the issue area of the GitHub just kept going for a long while because we saw It had been almost two months since the last update for users and 19 days since any public work had been done on the project on GitHub.

    The lead developer is back and did issue an update today, but he is openly asking for what everyone knows the project needs- more developers who can keep up with merging the newest Firefox stable updates with the Iceraven specific code and code borrowed from FF's nightly and beta versions that FF says it does not plan to ever offer in its stable version, and/or code some new user options and features (Iceraven also bases some of its code that gets rid of proprietary telemetry on F-Droid's Fennec browser, which despite being named after a codename for an old version of Firefox, is actually a current fork.).

    That's sort of what the browser is- it's the zillions of options browser, like the type of choices one usually only get from desktop browsers.

    Anyway, it badly needs developers.

    Here's the GitHub:

    https://github.com/fork-maintainers/iceraven-browser

    They'd love to have some people jump in and do some pull requests and coding. Interfect (GitHub screen name) is the guy you'd want to talk to about becoming a maintainer, which the project badly needs more of, but you could also just look at issues and write patches and pull requests and such and see what he uplifts.

    This would be a great opportunity for a developer to gain experience or just contribute to a cool browser for the good of the community or because he or she wants to.

    I am told CI and testing is one area of need, but it is not the only one.

    We're sort of down to one guy and he's basically admitted he can't do everything he should do on a reliable consistent basis because of his real job and other things. Yet, despite that, at least for my needs, Iceraven is far and away the best Android browser. I really don't know want I'd use if it didn't exist- I don't like thinking about it.

    We need to parachute some more developers in so people can feel good about it being supported and getting prompt security updates (Some of which are just a matter of adding from upstream as they do new stable releases). Tell people I sent you if you feel like you need to cite a person, but you don't need to.

    The browser is open-source and all that good stuff as well.
