    Should you use Fragment Factory or static "NewInstance" method when creating a fragment?

    Posted: 19 Mar 2022 11:07 PM PDT

    I've recently learnt a bit about Fragment Factory and creating your own implementation if your fragment needs dependencies.

    However, I'm more used to seeing a simple static newInstance() method which accepts the dependencies that the fragment needs as parameters, then sets them into the fragment bundle. This way, if the fragment gets recreated, it'll pick up these dependencies in the bundle and re-use them.

    I'd like some opinions on which way method I should use going forward when I want to create a fragment which requires some dependencies to function (say it needs to be passed something to actually work)?

    I haven't looked much into Fragment Factory yet, but it seems a newInstance() method seems to be pretty much the same thing. But I think the Fragment Factory seems to be more "proper" since it's using a constructor instead of a bundle to pass dependencies.

    How do you measure maximum user limit of your app?

    Posted: 20 Mar 2022 02:11 AM PDT

    Let's say your app talks with your backend. And your users are around the world. I wonder how you test concurrent user limits of your app. Do you test the response time of your app across countries?

    Any Twitch channels with a focus on android or kotlin worth following?

    Posted: 19 Mar 2022 10:20 AM PDT

    Should I immediately switch to Kotlin?

    Posted: 19 Mar 2022 04:39 AM PDT

    I've been coding Android Apps in Java for many years now and I know that Kotlin is considered to be the future. So my question is this:

    Should I force myself to switch to Kotlin or can I keep coding in Java, publish some apps and when I have the time to do so, learn Kotlin?

    Most code examples online are nowadays in Kotlin, even the Google Docs are not always in both languages any more, but there are still examples of huge Java Apps, most prominently Telegram (which I might add is the app with which I had the least trouble on my phone)

    Any help, advice or opinion is welcome...

    How to improve Conversion rate? All my app's are below the median and I'm not sure why.

    Posted: 20 Mar 2022 01:20 AM PDT

    Hello everyone,

    As the title says, I am looking for some strategies from other developers at how I can improve the conversion rate of my mobile apps. I develop mobile puzzle games and currently have 6 apps released all with conversion rates lower than the medians. I do some A/B testing now and then but I don't get much differences between the variants. (I guess my variants don't differ enough).

    In the puzzle games category, the 25th 50th and 75th percentiles conversion rate are 12.60% 20.15% and 29.71% respectively.

    Here are the numbers for my games:

    As you can see, apart from Orixo, most of my apps have a pretty low conversion rate. I've seen other threads talking about conversion rates in the 30 and 40%. I added the store listings for my games in case someone sees some obvious issues I'm missing. What am I doing wrong here? How do you guys tackle the issue with low conversion rate? Is A/B testing with store listing experiments the only way?

    MVVM with form input?

    Posted: 19 Mar 2022 01:33 PM PDT

    How would you guys architect this?

    I'm imagining my edit texts maybe updating some string state inside the view model which performs validations and then emits events to the view? Not sure what this state would look like though

    Or don't update string state and just do validation in the view?

    Could use some help, thanks!

    Comparing iOS TableView and Android RecyclerView

    Android Dev Newbie

    Posted: 19 Mar 2022 02:08 AM PDT

    I'm currently a uni student in the U.S. and I started off in web development but I didn't really find it fun. So after further exploring I garnered interest for mobile development and I've come up with some cool project ideas I hope to implement.

    Although, I've had people tell me that I'll struggle to find a junior position in this field once I graduate or the demand for mobile development is in IOS for the U.S. job market. Im hoping they're wrong because even though most jobs are in web dev, I can't get myself to enjoy it(in all due respect), and that Xcode is supposedly a terrible IDE but I'm obviously gonna try it out.

    To keep it short, I wanted to ask any U.S. based android devs about their experience on landing a junior position as a new grad and how that went.

    Also a bit off topic, but I've been following this roadmap for guidance, and wanted to know if it's reliable. Again I'm not too familiar with mobile dev. as I'm used to web dev practices. I'm open to any advice. Thank You.

    SQL Query Builder for Android

    Posted: 19 Mar 2022 08:50 AM PDT

    Hi everyone! I've been working on an app in my downtime, which lets you track your income and expenses. Architecture is simple. The app has a DiffUtil based RecyclerView which is updated by the Flow emitted by Room.

    While building it, I faced a challenge. I wanted to build a filtering system that'd let users stack multiple filters like medium, time, type or amount etc on top of one another. The initial method that I thought of was to write Room DAOs for every combination of filters, but this was clearly unscalable and error prone.

    So, I started looking for solutions, and found out that Room lets you run your own custom queries using the @Raw annotation. Moreover, you can observer the result of the query, which was great for the pattern that I was using.

    I ended up writing a separate class for generating parts of the SQL query based on what filters were applied at the moment. Wrote up an article about it, which can be found here: https://sanskar10100.hashnode.dev/querybuilder-how-i-wrote-a-runtime-sql-query-generator-for-an-android-app

    I'm not by any means promoting the app. Just happy that I figured it out on my own and want to let people know that something like this exists in Room. Is there something that I could've done better? I feel like the code for checking each filter became a bit repetitive and could be optimised, but I couldn't figure out how to do it well for Enums.

    is there a method to disable chrome to open link in browser?

    Posted: 19 Mar 2022 01:40 PM PDT

    I've developed an app that use deep links, all works if i disable the chrome app. When i go to active it again, automatically start to open link in browser, I've already disabled the option for chrome to open links, but the problem persist. My deep-link is not verified, I built it "above" another app, so I can't add the app in .well-known . (Sorry for me English)

    Is upgrading from SATA SSD to NVME will improve the build speed?

    Posted: 19 Mar 2022 03:27 AM PDT

    I'm upgrading my 5 years old PC to 12700F + 64GB Ram. Thinking If to remain my SATA SSD or upgrade to NMVE will improve the compile speed? Getting 3-4 minutes of build time every compile at the moment.

    How can I know which version of view pager 2 I am using?

    Posted: 19 Mar 2022 12:45 PM PDT

    Does anyone know how can I check the actual version of viewpager2 which I am using?

    I build a simple hello world project by only including

    implementation 'androidx.navigation:navigation-fragment:2.4.1' implementation 'androidx.navigation:navigation-ui:2.4.1' 

    But I was able to use ViewPager2 even I didn't explicit spell out view pager 2 library.

    May I know, how can I know which version of view pager 2 I am using?

    Hosting App On Cloud

    Posted: 19 Mar 2022 08:58 AM PDT

    Hi,

    This might be a stupid question, but I have an app that is too big in size. Is it possible to host the app on a cloud or some type of online service and create another app that just sends data to the first app to be processed and then the app sends back the processed data to be displayed in the second app? For example, I upload the BIG app with all functionality online somewhere(I have no idea what to use) then I create a small app that sends data (picture or audio) to the BIG app, and the BIG app processes it and sends the result back to the small app.

    Flutter replacing native development

    Posted: 19 Mar 2022 04:09 PM PDT

    Hi to everyone! Are you guys thinking that flutter will replace native development? I have a friend of mine who claims that, but i think it otherwise, you have so much power and control with native development. What are your opinions?

    Оfficial "contract" with Google as an Android developer?

    Posted: 19 Mar 2022 08:25 AM PDT

    My bank required me to provide them with the official contract confirming that I work with Google Play as an android developer as a proof of the proof of the legality of the origin of the incoming funds.

    As far as I know there is no such thing.. Have anybody had such an issue? Will Google provide me with some sort of an official confirmation of my "employment"?

    Not sure if this is the right sub, but hopefully somebody will have an answer.

    Is it possible to stream system sounds over WebRTC?

    Posted: 18 Mar 2022 12:11 PM PDT

    I was playing with WebRTC for a while and it seems I like it, but how can I make it to stream an internal sounds?

    This SO question pretty clearly describes what I've tried to implement too and didn't succeed with the attempt.

    Has anyone have a working example of internal sound streaming over WebRTC? Is it even possible without the library source code modifications?

    I want to start practicing data structures & algos using Kotlin before I jump into interviewing. Does anyone know any good resources to learn DSA using Kotlin specifically? There are a few books online and articles here and there but none have many reviews. Most of the popular resources are in Java. Any suggestions help!

    Account terminate due to "associated" with other terminated account

    Posted: 17 Mar 2022 11:59 PM PDT

    After waiting more than 1 month for appeal result. I thought my app violated any serious policy that lead to the permanent termination as my account doesn't have any strikes before.

    Recently I received reply from Google that they can't not reinstate my account because they found "strong indications" that my developer account is sharing information with, or is related to other developer accounts that have been terminated before. It's nonsense, my account is 6 years old, doesn't have any app suspended before. How can it be associated with someone else account ? They also refused to provide me the associated account name and give me no choice to prove that I'm innocent.

    I can't stand to watch all my 6 years of hard word going down the drain. I'm now planning to get a lawyer to help with my case but I'm not based in US and not familiar with the law there. Appreciate if someone can help point me to the right direction. I'm really upset and feeling helpless now. Thank you!

    (20-Mar-2022): Add my ticket number 7-0985000032436 in case anyone at Google read my post can help me to share to your colleague for reviewing.
