    The feeling of being a little overwhelmed

    Posted: 12 Dec 2020 02:23 AM PST

    Hello,

    I've been working for a little over a year in Android development and I'm learning new things every day. I feel like there are constantly new concepts and new libraries to know about, and it's really hard to keep up with everything.

    I'm alone on my project and I'm the only Android developer in my company. I'm afraid to provide bad code because I don't know all the concepts.

    Is there a way to measure the quality of your code? We use SonarQube but I would like to know if there is something else, something more advanced. I try to look at open-source projects on github with the latest up-to-date technos (koin, retrofit, room, paging, navigation, livedata, flow, viewmodel, rxjava...) but I find it hard to adapt it to my project which is more and more complex as the days go by.

    Do you feel the same as me? ._.

    Does Google's Android w/ Kotlin course get better?

    Posted: 11 Dec 2020 05:00 PM PST

    Asked this in the weekly questions thread but I was impatient, sorry.

    I'm talking about the Udacity course with video lectures and coding assignments, lesson 1 was an alright introduction but up to lesson 3, the videos just feel stale and while the theory behind the concepts gets explained relatively well, the coding part is just so confusing to follow with little to no explanation on what the instructor is doing. It could just be a temporary obstacle to overcome.. or is it? is the course still worth worth the time or is there something potentially better out there? checking the youtube comments on those lectures, it seems like at least a few are sharing my sentiment..

    Merging two apps (one paid, one free) into a free one?

    Posted: 12 Dec 2020 05:10 AM PST

    One of my oldest apps is split in two, one free version with ads and a paid one without ads. This seemed like a good idea back then but now only has downsides. So with the next big update I want to merge the too apps into one with a single IAP to remove the ads.

    So the current plan is to replace the old free one with the new version and replace the old paid one with a placeholder app that includes instruction on how to get the IAP for the free version for free (as they already removed the ads by buying the ad-free version).

    My problem with this is: How do I get any info from the paid app that I can use on my side to verify the purchase? I have the order ids of all customers but matching those per hand is impractical. Is there a way to get the order id inside the app? I only see something similar for the billing API for IAPs but not for the purchase of the app itself.

    If the app would be able to get the oder id from the app itself it could call my backend and spawn a key for the IAP for the new version. But where to get the id from? Is there a best practise for that use-case? I haven't found anything it that regard as everything seems to resolve around IAPs and not the handling of purchased apps.

    AdMob - additional ad sources payment

    Posted: 12 Dec 2020 06:02 AM PST

    I was wondering if I add other Ad sources in my AdMob account would I receive the money from the other sources in my AdMob account or in the account of whichever source's ad is displayed?

    Sensitive app permissions

    Posted: 11 Dec 2020 03:43 PM PST

    We're developing an app that uses "sensitive permissions" for "Device automation." This app is similar to others in the app store (obviously we feel our app "does it better") that use the same permissions. Clearly, these apps are not running into the same issues that we are having with the permissions policy or they wouldn't be in the store, and some of these apps are rather minor and recently updated. We've created a seven-minute video that showcases the app's core functionalities, permission declarations and app navigation. We've also provided a five-page document that further zeros in on the app's core functionalities, but we still can't get a win here.

    WHAT HAVE YOU DONE HERE, EXACTLY, TO SUCCESSFULLY USE SENSITIVE APP PERMISSIONS?

    Cheers.

    I have experience with C++. How much Java should I learn before starting Kotlin?

    Posted: 12 Dec 2020 03:14 AM PST

    I am interested in Android Dev and as stated by many people that Kotlin is the language for android dev I'm looking forward to learn it. I have experience with C++ but I use them for programming contests on sites like CodeChef, CodeForces nothing more than that. I know basic C++, STL and basic OOP concepts.

    I have started learning Java and done with the basics. How much Java should I learn before I can start learning Kotlin and Android?

    How to use NFC Tags with Android Studio: Detect, Read and Write NFCs

    Posted: 12 Dec 2020 03:13 AM PST

    Near-Field-Communication (NFC) is quite similar to QR codes. Recently, there has been a surge in contactless NFC usage as seen by the new trend of mobile payment like Google Pay and Apple Pay. This article explains how to use NFC Tags with Android Studio.

    How to use NFC Tags with Android Studio: Detect, Read and Write NFCs

    Hi All!

    https://itnext.io/how-to-use-nfc-tags-with-android-studio-detect-read-and-write-nfcs-42f1d60b033

    I compiled a really simple guide and walkthrough to help kickstart anyone who is interested in using NFCs! This was done during an Android Mod in SUTD, where we created a time-tracking app called SnapTrack.

    Scouring the internet and finding useful material for my use-case was hard. I needed to do 4 things which I thought would be easy to find: detecting (NFC device information) within the app, outside the app, reading and writing the NFC.

    I hope anyone who is interesting in Android App Dev or NFCs would find use for this guide!

    Use Apache 2.0 libraries with LGPL v2.1

    Posted: 12 Dec 2020 02:42 AM PST

    The question is rather simple, but I have a hard time finding the answer to it online.
    I am making an Android application, that after developing needs to be licensed under LGPL v2.1. Since most open source Android libraries have Apache 2.0 license, I am wondering can I use those libraries in my project.

    Would you be interested in a service that helps create test cases for your app?

    Posted: 11 Dec 2020 09:50 PM PST

    I am thinking of building a service that looks at your app and automatically creates test cases. Would be grateful if folks can provide feedback.

    Are these good concept for detecting App online status?

    Posted: 12 Dec 2020 01:31 AM PST

    Hello there,

    I know Java some and want to develop an App of my own. Currently, many developing reference these day documented in kotlin. Many of resources had been explained using Kotlin. Now, I intend to code my project in Kotlin.

    Anyway, I'm a newbie for Kotlin and my App need to get data from Internet so I need a fucntion which be able to inform user status of their internet connection. I'm also newbie in Reactive Rx but I've found some interesting articles that could do the trick.

    Could these concept from articles below really helpful?

    should I include them into my project or should I just simply test it?

    Is your App online? Conceptual with RxKotlin/Java Pt.2

    Thanks a lot for any suggestion in advance!

    Anyone know how to do ASO?

    Posted: 11 Dec 2020 12:37 PM PST

    I've intermittently read about it for months and I still have no idea how it works.

    I search online and all I find are companies promising I will be the top #1 app in the Play Store with just the low low price of 300$ per month, or $2000 to have someone else do it for me. Then I open their free trial tools and I'm overwhelmed by their UI. I have no idea what to do. And if I search their video tutorials it's almost always some foreign person talking with an incomprehensible accent and not explaining what I should do as a beginner.

    Is there a FREE and EASY way to do it?

    Google Play: "Verify your credentials as a news publisher"?

    Posted: 11 Dec 2020 11:49 AM PST

    I built a fairly simple api that calls the NewsAPI service and stores everything in RecyclerViews. It can search for stories matching user input, 'favorite' stories through a webview, and is updated daily from the NewsAPI. I entertained the notion of putting it on the Google Play store for free as part of my portfolio but I was met with the quoted line above.

    Am I able to put this app on the Play Store without incurring any penalty or something like that? I, obviously, have no ties to any media outlet or develop my own content so I'm not sure if this actually counts as a "news app" but still. Has anyone experienced something like this?

    Thanks in advance.

    To protect against decompiling/reverse engineering a social media app, what code should live on the server and what code can you safely leave on the client side (user's phone)?

    Posted: 11 Dec 2020 11:29 AM PST

    According to the Firebase website: "...application logic is best controlled on the server to avoid tampering on the client side". I'm new to android dev, so I don't really have the experience to know which code should live on the client side and which should live on the server.

    I wanted to make a local multi-player card game with my friend. What library should I use?

    Posted: 11 Dec 2020 09:40 AM PST

    Hey guys, I cannot seem to find enough info on how to make players connect with each other locally, so they can play under the same wifi. I have seen implementations with nodejs's socket.io Is there something less complicated than this? If anyone could point me to the right direction I would be grateful!
