Personal Life

Surgery or no surgery? That was the most toughest question of my life.

My first baby was born on 1st January 2019. What an amazing coincidence. Right? Those days were truly beautiful and amazing. A baby in the house redefines the whole atmosphere. There comes this strange energy in the environment, in people, and in things. Everyone smiles more, laughs more and enjoys more. Everyone starts feeling young or even childish most of the time. And that’s what I wanted to see a lot. Happy faces all around.


Brain Tumor, Baby, Public Speaking, Writing, Open Source, and Mountains!

Hello folks, it’s that time of the year (or maybe a little late) where I am supposed to reflect on my past year and make some new year resolution goals. Since I couldn’t write the year in review for the previous year 2019, so this article is going to about that. Next week, I will write the year in review of the year 2020, which has been a lot challenging for everyone around the globe due to Covid-19 pandemic.

I created the outline of this review and planned it about a year ago back in January 2020. But its been…


I am still looking for your phone number, so I can talk to you.

Today is Mother’s day and it’s really great. And I wish all the people and their mothers well wishes. I don’t need a mother’s day to write this article, but I feel that today this would make more sense than other days.

There’s not a single day when I haven’t missed my mother’s presence in some way. It’s been 13 years so far, and I always had thought that over time this feeling will fade away. But as I see my 2 year toddler growing up in front me, and I see how much mother is important to him and…


It took me 10 years to solve the Rubix Cube. Here’s the story.

🎯 Let me tell you a Rubix Cube Story today. Back in 2010, I came back home for a 2 months vacation from University. I participated in a Speed Rubix Competition when I had no idea how to solve a cube. I lost it big way and brought that cube to home. For 2 weeks, I watched many videos and tried to learn it but gave up at end frustratingly.

My father, who was a laborer in power loom factory with very less knowledge but he was very intelligent in machines and mechanics. He saw the cube laying around and…

A simple approach to pass the Parcelable data in Jetpack Compose Navigation

NOTE: The Jetpack Compose team doesn’t recommend passing Parcelable in the navigation composable routes. Instead the route structure in Navigation Compose has the best analog with a restful web service so developers should use bookDetails/{bookid} not bookDetails/{a whole set of fields representing a book} which is essentially what passing a Parcelable is doing. There’s a new issue created to update the official Google Docs to explain the best practices for passing complex arguments like Parcelable in the composable routes. You can see it on this Issue Tracker link.

While trying to create a simple demo UI of a books app…


What happens if you ignore her and don’t respond to her call.

It was evening. And I was trying to fix a runtime crash for an Android project at work. I was fully focused in the debugging and was going through breakpoints line by line. As a developer, you can understand that this is a very sensitive moment where need to observe bunch of variable values and figure out what’s happening with those values.

I was fully invested in these random lines that suddenly my 2 year toddler baby grabbed my hand on computer mouse and tried to get me somewhere. …


A step-by-step tutorial on how to use CometChat SDK to create chat for Android telehealth apps like Zocdoc

A major result of the Covid-19 pandemic has been the rapid widespread adoption of telehealth technologies. Usage of apps like Zocdoc have grown dramatically, and have allowed patients to connect with their doctors virtually through text chat and audio/video calls. The demand for these and similar services has skyrocketed, with no indication it will slow down, even after the pandemic is over.

As an indie Android developer, advanced chat features like read receipts or push notifications in your healthcare app can be tricky and therefore time-consuming to implement which is why I look to CometChat.

CometChat is a flexible developer…


What’s next for normal Android developers and open source library creators?

Update — 11th February 2021

To better support the community in this migration, JFrog has extended the JCenter new package versions submission deadline through March 31st 2021. This means that open source library creators who have libraries hosted on JCenter through Bintray can add more versions till March 31st 2021.

For normal Android app developers, the JCenter repository will keep serving packages for 12 months until February 1st 2022. Only the JCenter REST API and UI will be sunsetted on May 1st 2021. This means that if your app uses jcenter maven for any third-party libraries, then your app can…


When coding and parenting come face to face!

Every year on 1st January, people around the world celebrate new year. But for me, it’s been different for 2 years. My 2 year old son was born on 1st January, 2019. What a coincidence that maybe, but its been really amazing.

Before this little beautiful bundle of joy, aka a “top class toddler”, I would have never imagined the things I witnessed, feelings I observed, and days I enjoyed. I realized that a baby in the house changes the whole dynamic of the house and its culture.

A new baby is like the beginning of all things — wonder…
