    Using Java for Android app development in 2021

    Posted: 01 Jan 2021 09:51 PM PST

    Is it okay to learn Android app development in Java instead of Kotlin? Are both the languages supported equally by Google? Will it be advisable to keep on using Java in the foreseeable future?

    The Great 2021 /r/AndroidDev User Survey

    Posted: 02 Jan 2021 07:29 AM PST

    Hey all, happy new year!

    As discussed at the end of 2020, the 2nd step of the subreddit improvement plan is getting feedback from YOU, the actual users!

    I've created a survey to get your thoughts on every rule, as well as more general feedback. Every question is optional, but I'd really appreciate it if you could answer as many as possible.


    A few notes:

    • All responses are public, so don't reveal anything personal!
    • The survey will run for at least a couple of weeks, or until it receives a few hundred responses.
    • A summary post with conclusions will be posted a week or two after the survey closes.
    • The more responses the better, so feel free to pass it on to colleagues / friends.

    Here's the link, one more time:

    Retained Instance Library

    Posted: 02 Jan 2021 06:41 AM PST

    Hey, all!

    Few months ago I created a small library to "retain instances" on Android without needing to directly inherit from Android's ViewModel. Now, I added support to Compose UI and Navigation, apart from Activities & Fragments.

    My main motivation is to use it in KMP projects where I do create my VMs as a KMP and I simple use the "retain" method to create the instance connected to the UI LifecycleOwner. The library also keep in mind the current Ambient while retrieving defaultArgs and which ViewModelStoreOwner and SavedStateRegistryOwner it will use to be retained.

    I only use it in 3 side projects but it has been useful for me so far and any feedback would be very welcomed about the general idea or implementation details. Better alternatives or an official way of doing it in Compose is also welcomed!

    Here is the library source code: https://github.com/marcellogalhardo/retained

    A simple usage from one of my side projects:

    import dev.marcellogalhardo.retained.compose.retain // Android Module. @Composable fun BackpackEditView() { val viewModel = retain { // this: RetainedContext val position = retainedHandle.get<Int>("position")!! BackpackEditViewModel(position, retainedScope) } BackpackEditView(viewModel) } // KMP Shared Module. class BackpackEditViewModel( itemPosition: Int, scope: CoroutineScope, // ... ) 

    Thanks a lot in advance!

    How long until google approves my application?

    Posted: 02 Jan 2021 02:51 PM PST

    I initially submitted the application on December 14 (internal testing / open testing / production) and so far only internal testing has been approved.

    The application is for one of my clients and should have been in production at least a week ago.

    Beginner-Bottom Navigation using navigation graph, is it proper?

    Posted: 02 Jan 2021 09:32 AM PST

    I am working on bottom navigation on my Java app where it has 3 menu. When each menu is clicked, they will navigate to their respective fragment.

    I discovered (so far) that there is 3 ways to implement this. First is by using getFragment() on main activity, it worked fine at first but then I encountered fatal error that said something like "onNavigationItemSelected" is null reference. I did try to fix by implementing suggestions from stack overflow and etc but it didn't work so I moved on to another method.

    Second method was by using navigation UI but I still got fatal error. This time it said the host Nav Fragment is null. I tried to fix by looking at the ID and so on..but to no avail..

    so the third method that I tried was by using navigation graph, but I did not see this method anywhere on the Internet so i think it might possibly not the proper way to do it but it works fine so far. So right now my navigation graph looks like this (which is messy) Navigation Graph. What do you think? To me, it looks messy and probably not the right way but it works fine so I'm kinda stuck here.

    TLDR; I'm stuck cause not sure if the method i'm implementing is the proper way (please click on the link to see how my nav graph looks right now). What do you think?

    Custom voice commands

    Posted: 02 Jan 2021 05:38 AM PST

    Hi everyone!

    I want to add a couple of voice commands to my app that controls garage doors via bluetooth, so it can be used more comfortably while getting home or getting in the car.

    So far I've only found the new integration with Google assistant, launched 3 months ago and that now only supports English (but I need Spanish).

    Is there no other way to achieve this? I'm finding hard to believe that after all these years with voice commands there's nothing else.

    Thanks!

    Anyone knows a weight scale with android sdk?

    Posted: 02 Jan 2021 08:09 AM PST

    Hi I wanna try to develop an app that connects to a weight scale over bluetooth (or wifi) but I can't find any brand that offers an open sdk for their scales.

    Has any of you tried to do something similar? If you could share some examples of scales I'd really appreciate it

    What will you recommend for personal app development

    Posted: 02 Jan 2021 09:58 AM PST

    Hi guys, I am planning to buy a MacBook but bit confused. Just wanted to check if somebody has already used android studio in latest MacBook Air and pro with M1 and what will you recommend?

    Also is 8GB enough given that M1 MacBooks are coming with unified memory.

    To Reddit Experts, I need to SMS reply to a four digit code as quickly as possible. I was wondering if there was a service that could do this or maybe someone could create Bot/AI that could do this on iOS/Android? Any recommendations would be much appreciated :)

    Published a Xamarin Forms app. Looking to trade honest feedback with another developer.

    Posted: 01 Jan 2021 08:38 PM PST

    Hey, I reviewed the rules twice so I hope this follows the guidelines, but anyway, I recently published a Xamarin Forms app. The design/UI/workflow, etc. was all done as a solo side project. I am looking to get in contact with some other developers to help get some quality feedback. I'd like to offer to do the same for another dev too. Let me know if you're interested.

    Best Practice on Staging and Production

    Posted: 02 Jan 2021 02:53 AM PST

    This might not be an Android specific question but asking here anyway. I'm currently doing back end(working mainly on APIs) for a couple of front end devs and I have both Staging and Production base URLs. Ideally, I would make the Production base URLs secret but for some reason I have to give this to the front end devs as well. In this scenario, is there a way for me to protect the Production database from malicious devs running evil code(e.g., if this was a social media project, doing an infinite loop of commenting to a post, etc.)?

    Help execing a "Native Lib" that's actually an executable

    Posted: 01 Jan 2021 06:21 PM PST

    Hi!

    I'm trying to do something horrible. Several horrible things, really.

    1. I want to launch an external Process
    2. That process exposes a web service
    3. For very good reasons, Android doesn't want you to do this, so you can't execute things in writeable areas like assets/ ...so I'm putting my executable in /jniLibs and naming it libipfs.so

    According to Stack Overflow and Google Support, this is the "right" way to do this if you have to do it at all.

    Buuut... It's not working. When I open the APK, I can see there's a root-level directory named 'libs' that contains my executable(s). But when I load '/data/apps/<package>/lib' from within the app, the directory is empty.

    Code where I try to exec the executable: https://github.com/swordsmanluke/bailiwick/blob/master/app/src/main/java/com/perfectlunacy/bailiwick/ipfs/IpfsClient.kt

    Android Test that validates whether the files are present: https://github.com/swordsmanluke/bailiwick/blob/master/app/src/androidTest/java/com/perfectlunacy/bailiwick/FindingExecutablesAndroidTest.kt

    build.gradle: https://github.com/swordsmanluke/bailiwick/blob/master/app/build.gradle

    Thank you!

    What app would you want to exist but it doesn't?

    Posted: 02 Jan 2021 02:11 AM PST
