App is crashing for some reason
So this project I'm making for college keeps crashing whenever I click on the first image.
I want to know why it keeps crashing and if there are any alternatives I can use instead.
Here's the .kt code:
(The if statement inside the imagebtn1.onClickListener is where it usually crashes)

Considering a Shift from Android Development to Full-Stack Development – Need Advice!
Hi everyone,
I’m currently an Android Developer Intern at a company and have been told by my team manager and lead that I’m quite good at Android development. They’ve suggested that I learn server-side development to become a full-stack developer.
However, I’m a bit confused and torn about whether to stick with Android development or expand my skills to include server-side knowledge.
I’d love to hear from those who have been in a similar situation or have insights on the following:

A copycat app on Google Play stole my brand identity, what can I do about it?
Dear Community of Android developers,
I have been developing and distributing my app on the Google Play Store with my brand since 2019.
An copycat app released 1 month ago is copying my brand identity.
The name is 100% the same and it includes my main brand name.
The package name is the same as mine only shorter.
The logo is very similar, and can be easily confused at a small size.
The functionality is the same, but I'm fine with competition.
I've put a lot of money and energy into buil...

App update issues
Hi all, having issues trying to push out an update at the moment, essentially version 267 of our app is live in play console and is non compliant because of the changes to foreground services rules, so we have after a couple of attempts, we have version 288, no foreground services at all, we’ve reverted back to fine and course locations which is fine, however it’s being rejected due to the current live version. The suggestion in our appeal was to go to the release and ensure 267 is in the ‘not i...

Do you use Live Edit?
It never worked for me.
After a change (even the smallest one), I'm waiting for 10+s only for Android Studio to notify me it failed or it's "out of date" (I just added a character in an hardcoded String in a Text, come on Android Studio you got this...). So I'm just wasting time most often than not.
Also, the errors never make sense, sometimes it's "Analyze Error ... compose.foundation.ExperimentalFoundationApi", sometimes it's "Unsupported change ... added new class some enum that'...

It's possible to write an Android APP using only NDK ?
I would like to write apps using only C++. I guess the way to do this is to use NDK, right ?
But all the examples I have seen of NDK use, is for some auxiliary C++ code.
It's possible to develop complete apps only using C++ ? Anyone has a complete example of a simple app using NDK ?
If there's another way to develop for Android besides NDK I'd also like to know. Thanks...

Avoiding "Open in another app?" popup when redirecting back to an Android app
Hi everyone,
I'm building an Android app that uses OAuth2 authentication.
After the login flow, the OAuth provider redirects the user back to my app using a custom URI scheme.
I've observed the following behavior:
In Chrome, the redirect works perfectly — my app opens automatically without any issue.
In Firefox, however, a "Do you want to open this link in another app?" popup appears before opening the app.
I've also noticed that in TikTok, when using Facebook login, even if it op...

Which tool allows to make screen recordings, that draws a fingers imitating gestures that user makes?
I would like to produce a lot of app demo videos on how to use the app. I guess there is a tool that allows to capture video from the screen of the device that also renders fingers of the user corresponding to gestures the real user makes. It seems I've seen such videos..
Are you aware of such tool?
Some time ago people were using a cursor looking like a human finger (actually, a photo of the finger), and run the app in Simulator while capturing region of the screen, but results looked imperf...

FRP Policy Applied via DevicePolicyManager, but After Reset, Device Asks for Unknown Google Account Instead of Set FRP Email
Scenario:
I'm working on a Device Owner app that sets Factory Reset Protection (FRP) using DevicePolicyManager.setFactoryResetProtectionPolicy() on a Walton NEXG N74 (Android 10+). The app becomes Device Owner successfully, and the FRP policy is applied and confirmed. The strange issue is:
After factory reset, the FRP screen does appear, BUT it asks for a different (unknown) Google account, NOT the one I explicitly set in the FRP policy.
Steps I followed:

Help: Unity app to take RAW (DNG) photo on with fixed settings
I have a simple Android app that listens for a TCP signal and takes a photo when it receives one.
Now I want to make sure the photo is saved in RAW (DNG) format, and that it's taken with fixed camera settings:
Shutter speed: 1/120
Fixed ISO
Fixed white balance
No auto-exposure or auto-white-balance changes between shots
The goal is to take multiple shots under consistent conditions, without any variation in color or exposure.
Any advice on how to achieve this?...

Is your company pressuring teams to adopt AI tools?
We have been having a couple of AI workshops where we learn about AI tools, prompt engineering and AI in general.
All of this is generally pretty interesting however we are also being told that we need to have "AI related goals", use Cursor IDE, propose ideas to enhance our workflow with AI, etc.
I'm not opposed to this but it feels kinda odd, most of the tools I've been learning about are related to interacting with Figma, Github, Confluence or analytics platforms to make it "easier" but to m...
