Is there an efficient way to fetch buckets in MediaStore with count?
I'm trying to query all the buckets in external uri with their count from `contentResolver`.
I tried two approaches and both have big drawbacks.
## Approach 1:
* Use `contentResolver`'s query API with bundles to use `ContentResolver.QUERY_ARG_SORT_COLUMNS` and fetch the Bundles.
* Query each Bundle Id for the count of files in each bundle.
### Drawback in this
* Which I feel is inefficient due to querying in loop.
* required BuildVersion.R :(
```

How do apps typically handle SDK's with OneTrust or consent management?
I'm integrating and setting up OneTrust for an app. OneTrust manages privacy and consent to help mobile apps comply with laws like GDPR, CCPA, and other regulations.
The process involves uploading the app bundle file, where it scans for SDK's the app uses, like Retrofit, Okhttp, Glide, Google, Exoplayer, among other libraries, then it categorizes each SDK into these groups: Strictly Necessary, Functional, Social Media, Performance, Targeting/Ads.
The idea is when a new user uses the app, a con...

Weird Painter and .size Modifier interaction when repeating image components
I found a peculiar interaction between size Modifier and Painter and I couldn't really find any clues as to why this is observed.
You can find the below mentioned code snippets here.
In particular in the component found at file ComponentWithPainter by checking the Preview and interacting with it, it eventually becomes apparent that the Image components seems to be drawn on each other (?) I am not really sure how to even ch...

App rejected for Broken Functionality, but everything works fine
Hi everyone,
I'm in the process of publishing an app I made for my first serious client (big deal for me hahaha), but I'm having a lot of trouble with the publishing process, since the app keeps getting rejected for issues that I cannot reproduce.
The first rejection was due to the privacy policy, and that one made sense, so I solved it.
The following rejections were violations of the Broken Functionality policy, respectively:
* **App is not responding** (second rejection) Your app i...

MacOS ADB won't stay connected to my phone for the life of me.

I updated Android and Studio and all platform tools SDKs to the latest (35).
I have two androids this is happening to both of them.
I restarted the computer about a dozen times. Restarting android phone(s) too.
I tried different ports in the mac and different wires.
It seems the phone shows up very intermittently. One second it'll show, then it'll disconnected. ADB will say it's offline, even though it's fully awake, plugged in, while also saying "USB debugging connect...

What is your app marketshare of Android devices on 64 bit vs 32 bit (CPU architecture / ABI) in 2025?
Google began preaching developers for Apps to add 64-bit support in 2017.
In August 2019, Google Play started requiring all new apps and app updates to include 64-bit versions.
In August 2021, Android devices with 64-bit capable hardware were prevented from downloading 32-bit only applications from the Google Play Store.
But there's no statistics I could find on what's the current market share for 32 vs 64 bit devices. Or rather, how many devices out there still support 32 bit only architectu...

Possible to enable Auto-Formatting on Save with ktfmt?

Calling ViewModel's onEvent in composable
I've been calling onEvent directly in my Compose code so far. I've encountered no issues.
But there are events where you need to call the event outside of onClick, e.g. for pagination or "marking as read".
I will be able to call that directly in Compose.
However, I also know about SideEffect {} composable. It's purpose is to call the code outside of compose, which, I guess, is what ViewModel is?
Please help me understand whether calling onEvent outside of SideEffect or LaunchedEffect is vali...

I noticed a user with some strange data. The user has a Samsung A51 5g running Android 13.
What seems to happen is the app is opened and closed multiple times during a day/night.
I have contact with the user and the app is not opened by the user.
The user never closes any app on the phone (swipe from recent). Has the phone in flight mode while sleeping and only use my app 2-3times a day.

21M, Built an App from Scratch – Now 230K+ Downloads, But Struggling with IAP
Hey everyone, I just wanted to share my journey as a solo dev. I’m 21, and about 7-8 months ago, I built my first app. No team, no budget, just me and my laptop. After launching, I had no funds for ads, so I focused purely on organic growth.
