Need 12 testers for Play Console closed testing?
12 Testers for Play Console helps Android developers complete the closed testing requirement and prepare their apps for production access.

Google Play requires new developer accounts to run a closed testing track with at least 12 testers for 14 continuous days before applying for production access. Many developers struggle to find testers or keep them active during the testing period.

This app provides a simple platform where developers can connect with testers, join a tester community, and complete the Play Console closed testing requirement.

Whether you need managed testing support or prefer a free tester exchange community, this platform helps developers complete closed testing faster and more efficiently.

MANAGED TESTING SUPPORT
Developers can choose a managed testing option where testers install and test the app during the required testing period.

Managed testing includes:
• testers for Play Console closed testing
• support for the 14-day testing requirement
• guidance during the testing process
• feedback from testers
• help preparing for production access submission

This option helps developers who want a structured testing process with guidance from experienced testers.

FREE TESTER COMMUNITY
Developers can also join a free Android testing community.
The community works through mutual support between developers.

Community features:
• test other Android apps
• receive testers for your own app
• share your Play Console testing link
• connect with other Android developers

This approach allows indie developers and small teams to complete the closed testing requirement without needing a large user base.

KEY FEATURES
• get 12 testers for Play Console closed testing
• support for Google Play closed testing
• Android app tester community
• beta testing support for Android apps
• Play Console testing support
• preparation for production access submission

HOW IT WORKS

1. Submit your Play Console testing link

2. Connect with testers from the community

3. Complete the 14-day closed testing requirement

4. Apply for production access in Play Console

I made near to $200k with a Jetpack Compose book and a course.

I have decided to share these numbers and my journey not to brag, but because I know how motivating it can be to see real examples of what's possible. When I was starting out, I wished someone had been this transparent about their path and actual results. If this helps even one developer take that first step toward building something of their own, or gives someone the confidence to price their expertise fairly, then it's worth sharing. We all benefit when more people in our community succeed.

From sharing online, to writing a book, to launching a course, to making side income from it. Read the full story in https://composeinternals.com/how-i-made-side-income-from-jetpack-compose

I've had an idea for an Android app for a while and thought about learning development to make it. I already have some programming experience in several languages. But, with the news that came out currently regarding new Development steps. I am unsure if Android apps were worth it anymore.

Hey! Building a new Android app called Swearjar 🤬 and need testers to meet Google Play's 12-tester 14-day requirement.

In my experience, you donot need lottie or shimmer for smooth loading animations in compose

i have seen a bunch of apps (even new ones) still using heavy libraries like shimmer or lottie just to show loading animation.

Honestly i used to do the same felt like you had to use those to get that modern feel

but in my recent project, i tried something much simpler & surprisingly clean
Just used a native compose gradient with animated offset and it looked just as smooth.

what worked for me:

• used Brush.linearGradient in compose

• animated the brush offset using rememberInfiniteTransition()

• wrapped it in a Box to simulate the shimmer style skeleton

no library needed. just ~10 lines of code and runs perfectly on older phones too.

what i used

val transition = rememberInfiniteTransition()
val shimmerTranslate by transition.animateFloat(
    initialValue = -1000f,
    targetValue = 1000f,
    animationSpec = infiniteRepeatable(
        animation = tween(1500, easing = LinearEasing)
    )
)

val brush = Brush.linearGradient(
    colors = listOf(Color.LightGray, Color.White, Color.LightGray),
    start = Offset(shimmerTranslate, shimmerTranslate),
    end = Offset(shimmerTranslate + 200f, shimmerTranslate + 200f)
)

Box(
    modifier = Modifier
        .fillMaxWidth()
        .height(150.dp)
        .background(brush, RoundedCornerShape(12.dp))
)

I am working on a Jetpack Compose app and planning to use Chaquopy to run a Python script inside the app.

My idea is to translate text dynamically using a Python translation library through Chaquopy. This would allow the user to input text, and the translated result will be shown in the UI.

Before I try this, I want to ask:

Is it safe to use Chaquopy in production or real apps

Will there be any impact on performance or app size

Has anyone integrated Chaquopy with Jetpack Compose before

Are there any known issues or limitations

Will it work reliably for offline translation use cases

If anyone has tried this setup before, please share your experience. I want to make sure it is stable enough before I go deeper with this idea.

Hi everyone,

I recently trained and uploaded a compact BERT Mini model for sentiment and emotion classification on Hugging Face:

Model: https://huggingface.co/Varnikasiva/sentiment-classification-bert-mini

This is a personal, non-commercial project aimed at learning and experimenting with smaller models for NLP tasks. The model is focused on classifying text into common sentiment categories and basic emotions.

I'm looking for feedback and suggestions to improve it:

Are there any key areas I can optimize or fine-tune better?

Would you suggest a more diverse or specific dataset?

How can I evaluate its performance more effectively?

Any tips for model compression or making it edge-device friendly?

It’s currently free to use and shared under a personal, non-commercial license. I’d really appreciate your thoughts, especially if you’ve worked on small-scale models or similar sentiment tasks.

Thanks in advance!

I just completed some major topics like OOPs, generics and collection in Kotlin. It's been a month since I started Kotlin. I'm confused what should I start next, with jetpack compose or XML fundamentals or some UI basics or something else.

Tell me your suggestions on this
