Senior Android Developer with a family: how do you find time for open-source projects?
Hi everyone, I’m a senior Android developer with over 7 years of experience. I love my job and constantly try to improve by reading articles and watching videos.
For a while now, I’ve wanted to enhance my GitHub profile with open-source projects—both to contribute to the community and to improve my professional visibility. Over the years, I’ve had several ideas, but after the initial excitement, I always end up abandoning them.
Between work, family, and personal life, it feels almost impossibl...

Compose Navigation
Ok, so I have a bottom bar in Compose with multiple tabs and two of them are "Today" and "History".
I can also open "Today" with a button click inside "History" , but in this case I don't want the selected tab to switch to "Today" ,but to remain on "History".
If I switch between tabs and select on "History" and I previously opened "Today" from "History", I want for "Today" to stay opened.
I have tried this in the NavHost:

Use of freelancers
Curious how many Android devs leverage freelancers for development help on their apps or use them for specific tasks/non-technical business work (SEO/Content Moderation).
Is this pretty common and where do people go to find freelancers?...

Is it legal to use Wikipedia content in my AI-powered mobile app?
Hi everyone,
I'm developing a mobile app dai where users can query Wikipedia articles, and an AI model summarizes and reformulates the content locally on their device. The AI doesn't modify Wikipedia itself, but it processes the text dynamically for better readability and brevity.
I know Wikipedia content is licensed under CC BY-SA 4.0, which allows reuse with attribution and requires derivative works to be licensed under the same...

Jetpack Compose different AppBar setting for each screen
What's the convention for making screens with different back button, titles, quick actions and overflow menus?
From what I know, composables should reuse the same scaffold.
But how do I setup different configurations of that scaffold, namely the toolbar, for the specific needs of each screen?...

"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:

I can't enter download mode to reinstall my system using Odin. The phone just keeps rebooting and nothing affects it
I can't do anything to get out of this and all of the 500 videos i watched about this ask you at some point to enter either of those to get out of the boot issue but the phone simply won't react. I am going crazy over this because that phone is almost new... I tried Odinn but it can't recognise the phone if it doesn't enter download and adb seem to need the phone to be able to boot. Can anyone help me ? This is all because of Magisk that i tried to unstall (the previous owner for a short period ...

Seeking Android Developer - Short term assistance
I built an Android app in native Java a few years ago. It used to target 31 and below. I am now revisiting it to make some simple updates. This app is still in the Play store. Its a B2B app and not consumer facing.
I need to make some updates to the app to bring it up to modern standards and requirements.
I deployed a local build to a device and noticed that there is some inset / full-screen behavior. Something about edge-to-edge?

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...

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 ...

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...
