Take home project: is it okay to refactor?
Hello, so I have this take-home project that I need to improve, fix bugs, etc. The project is using RxJava but I think it'd be better to use coroutines. However, I don't know if this might be seen negatively because I'm changing something that might o might not be important to them (like what if they want to see how I use RxJava?). The company did say they are migrating from RxJava to coroutines so maybe it's not a bad idea? But I'm not sure.
So the main question is, is it okay to refactor th...

SDK Activity communication with host app
Hi,
We are writing an Android SDK that contains many screens. All screens (fragments) are in a single activity.
We are thinking of using ActivityResultLauncher when starting the SDK (activity). In this way, we can send the necessary parameters at the beginning and return a result when the SDK is closed.
But there is also a request on the client side. There is an analytics tool in the app that will be the host and we want to send events here instantly while navigating the screens in the SDK. I...

Privacy Policy must not be presented as a Github link
Ok so I've attempted to submit an update to my app only to have it rejected by the reason mentioned in the title.
Now, I don't have my own website and it only says that the app cannot be presented as a github link, not that it can't be one.
So can I just put it as a bit ly link or something? Does anyone have any experiences with this problem?...

Best Approach for Developing a Free & Paid Android App with Jetpack Compose?
I’m planning to develop an Android app using Kotlin and Jetpack Compose. This will be my first paid app, and I also want to offer a free version with ads.
I have a few questions about the best approach to structuring the development:
1. Should I create two separate GitHub repositories, one for the free version and one for the paid version?
2. Is there a way to develop a single app where the ads are removed, and extra features are unlocked when the user pays?
3. If so, what’...

Bottom Nav Bar in Compose
Here's the situation, we want the bottom nav bar to be displayed in 4 major screens, navigating between these screens shouldn't re-render the bar (atleast not visually). When navigating deeper from the 4 major screens nav bar should not be visible. The implementation we used is to make a scaffold, and put the whole nav graph as it's content. To hide it in the nested screens we implemented a state that is derived from the current stack entry, that would hide or display the bar with a nice little ...

Customize Text Selection Toolbar in Jetpack Compose
I'm trying to customize the text selection toolbar for TextFields in Compose. I want to just keep the "Paste" option.
I have created a custom Impl of TextToolbar. It works most of the place but not for TextFields inside BottomSheets.

Good Android Programming(Java) Course/Tutorials?
Have Android Programming as a course in Uni and the teacher is crap at teaching our maybe I just dont resonate with his style of teaching. I know Java isn't really used anymore in Android Development but would have to learn that as our syllabus is based on that.
Also for some reason the teacher insists that we use the design view to create the software negligibly and focus on the programming part the most. So I have struggled to find any yt tutorials that take me from basic to intermidiate/adv...

About mentorships
Hi there! I've been working as an Android developer in the industry for about 8 months now. Recently, I got accepted into a mentorship program that's starting soon. I really want to make a good impression on my mentor and make the most out of the time we have together.

What's the proper way to manage variations across build variants for white label apps?
I've worked with some white label apps, but I still don't know the proper answer to this.
Is the answer simply to have all common code in the main source set, and to have all varying code in specific variant source sets?
One issue I see is what if you had a view model in the main source set, then suddenly this view model needs to do something slightly different for one build variant.
Do you end up copying and pasting the whole view model, duplicating it into that variant source set, then edit...

"App startup impacts everything: every time a developer starts the app or a tester runs a test, they pay the app startup tax" - Reddit app’s journey from 12.3 seconds to 3 seconds
When Reddit’s team discovered their app took 12 seconds to launch for p90 (90%!) users, they were shocked. With over 2 million DAUs on the Android app, that meant about 200,000 users were waiting for >12 seconds for the app to load.
Reddit's engineering team made game-changing improvements to their Android app, reducing cold start times by over 8 seconds from app launch to the Reddit feed.
Here’s how they did it:

How to hide a Header when scrolling down

And, I have some ’TabRow’ buttons underneath the ‘Header’ which show certain webpages. I want the Header to disappear when the User scrolls down and reappear when scrolling up. But, the Header refreshes with every Tab change.
Does anyone have any idea what to do, please? I tried to change the Header to a separate file too.

How to have access to full viewmodel with dagger 2 di inside test class to test compose ui elements.
i have a fragment. which i modified to use a jetpack compose screen and in that screen I'm passing the viewmodel which uses dagger 2 for dependency injection like this.
I know it is not really a good practice to put the viewmodel inside the composable , instead i should lift the states up but right now viewmodel is a mess and using very old libraries. I'm planning to shift to dagger hilt and couroutines instead of rx java and dagger2.
