About Vikas Soni

Hi, I’m Vikas Soni — an Android Developer, technical writer, and creator of Android Unplugged, a platform focused on Android engineering, architecture, performance, and developer productivity.

I build and write about modern Android development using Kotlin, Jetpack Compose, clean architecture, app performance practices, and scalable engineering patterns. My goal is to help Android developers ship better apps, debug faster, and grow into senior engineering roles.

What Android Unplugged Covers

Android Unplugged publishes practical guides, deep technical articles, and free tools for Android developers. Topics include Jetpack Compose, Android architecture, memory leak detection, app performance, Gradle workflows, mobile reliability, and interview preparation for SDE2 and SDE3 roles.

Tools and Products

Android Unplugged is home to developer tools like LeakLens, an AI-powered memory leak detection tool, and Gradle Lighthouse, a tool focused on architecture health scoring for Android and Kotlin Multiplatform projects.

My Background

I work as an Android Developer and have built production-grade mobile applications with a focus on robust architecture, performance, maintainability, and real-world product quality. My experience includes Android UI development, Jetpack Compose, architecture design, debugging memory leaks, and improving engineering workflows.

Writing and Community

I also publish Android development articles and technical tutorials for developers who want practical, implementation-focused guidance. My writing covers topics such as Android internals, performance optimization, software architecture, memory management, and interview preparation.

Play Store Uploads with Fastlane Supply - 4

Image
If you’ve ever manually uploaded an APK or AAB to the Google Play Store, you know it can be a tedious process. From filling out all the necessary metadata to selecting the correct APK version, it can feel like a lot of repetitive work. But with Fastlane Supply , you can automate this entire process — making your app releases smoother, faster, and error-free. In this section, we’ll explore how Fastlane Supply works and how to set it up to upload your Android app directly to the Play Store with ease. Step 1: Set Up Google Play API Access Before you can upload your app with Fastlane Supply , you need to set up Google Play API access . This ensures that Fastlane can communicate with the Play Store and upload your APK or AAB. Here’s how you can set up API access: Create a Google Cloud project : Go to the Google Cloud Console. Create a new project. Enable the Google Play Developer API : In the Cloud Console, search for and enable the Google Play Developer API . Create a service account ...

Cracking Android SDE2/SDE3 Interviews in 2026: Deep Dives, Code, Follow-ups | Part-2

  Architecture & Patterns Find Part -1 From Here Find Part -3 From Here 21. MVVM vs MVI? Interviewer: Compare MVVM and MVI — when choose MVI? Candidate: MVVM: View observes ViewModel state (StateFlow/LiveData), unidirectional updates. Simple for CRUD. MVVM (Model–View–ViewModel) How MVVM works View observes state from ViewModel ViewModel exposes data via LiveData or StateFlow View calls functions directly on ViewModel State is often split across multiple variables Typical MVVM flow View → ViewModel.method() ViewModel → update LiveData / StateFlow View ← observes updates Example MVVM pattern class ProfileViewModel : ViewModel () { val loading = MutableStateFlow( false ) val profile = MutableStateFlow<Profile?>( null ) val error = MutableStateFlow<String?>( null ) fun loadProfile () { loading.value = true // fetch profile } } Problems MVVM faces at scale State is scattered Hard to know which user action caused ...

JIT vs AOT Compilation | Android Runtime

Image
           D id you ever think, what happens when you install your app in your Android device, it shows INSTALLING for fraction of second and app get opens. What happens exactly behiend the scene? Found Interesting???? Cool !!! let’s clear all the doubt in this blog. You would have definetely read the buzz words JIT(Just-in-time) and AOT(Ahead of time) at many ocassions. We’ll dig it down in details in this article, stay tuned…. Android apps run on Android Runtime (ART) , which replaced Dalvik since Android 5.0 (Lollipop). ART supports both JIT (Just-In-Time) Compilation and AOT (Ahead-Of-Time) Compilation to improve performance and efficiency. JIT (Just-In-Time) Compilation How it Works: Compiles bytecode into native machine code at runtime (when the app is executed). Stores frequently used methods in memory to speed up subsequent executions. Advantages: Faster app installation because it doesn’t require full compilation beforehand. Reduces s...

From ‘Master’ to ‘Main’: The Meaning Behind Git’s Naming Shift

Image
                             Git changed its default branch name from master to main due to concerns about inclusivity and to remove references to terms with problematic historical connotations. The term master has been associated with slavery, and many tech communities sought to use more neutral and inclusive language. Reason for the Change: Inclusivity & Sensitivity- Many organizations aimed to remove racially charged terminology from software development. Consistency Across Communities- Other projects and platforms, such as Github, Gitlab, and software frameworks, also made similar changes. Modern Naming Conventions- main is a cleaner and more intuitive name, as it represents the primary branch of a repository. Interesting Facts —  It wasn’t originally about slavery  — The term Git did not originate from the master/slave concept used in computing. It likely came from Bitkeeper , a version contro...

Android Device Security: Sandboxing, Rooting, and Attestation Explained

Image
  As Android developers, understanding device security is essential to protect our apps and users. In this comprehensive guide, we’ll explore Android’s security architecture, including sandboxing, rooting and jailbreaking, and how to implement device attestation using SafetyNet and Play Integrity. We’ll cover each topic in detail, providing code snippets and best practices, following. What is Sandboxing in Android? Sandboxing is the security mechanism that isolates each app’s code and data from other apps and from the underlying system. In Android, this ensures that one app cannot freely read or modify another app’s private data or perform privileged operations unless explicit permissions or IPC channels are used.​ High-Level Idea Each app runs in its own isolated environment with: Its own Linux user ID (UID) and process. Its own private data directory (e.g., /data/data/<package_name>/ ). By default: One app cannot directly access another app’s files. An app cannot perfo...
