Then we will look at various parts of the source that can be modified to change the way the Android Operating System looks and works. People who wish to change the core Android OS itself, or people looking forward to release their own Android-based hard… more

NFC on Android is not just about payments. There are a plethora of actions achieveable by that small tap of your phone, and surprisingly, NFC hasn’t been applied to as many fields as it should have been. more

Making your App stand out from competitiors can be tough. Often the UI makes the difference, especially how the users are interacting with the app. Users want intuituve and easy control over the app, and you want to cram in as many options as possible while keeping simple. The most successful solution to improve UI is to implement touch gestures like (Un)pinch, 1/2/3/4-finger drags, swipes, flick… more

Using three free to use tools/services, namely Github, Travis-CI and Google Play Developer APIs, we can automate the whole process from pusing changes in source code to compilation, signing, and finally publishing to Google Play Store. more

We will be looking at how a complete home automation system (from hardware to the user interface) can be prototyped with various JS based technologies. more

I had been to DroidCon last year to describe how to modify the Androi OS and make your own custom ROM build. This time I wish to describe the next step which involves setting up a set of source code mirrors, a code review server, a bug tracker, and a CI server to be able to create a end-to-end CI for Android ROM building. This pertains to both community based ROM projects like CyanogenMod, AOKP, … more

Gradle throws the doors open for build variants and flavours. As the name suggests both allow you to build slightly different editions of your app, while reusing the core code that is common. We will be exploring what all can be common-ified, and how best can flavours and variants be used. Also we will look at how dependencies and libraries can also be managed per-flavour or per-variant. more

Last summer, I and my college mates embarked upon a fun project - “Let us make an app that can search all hyperlocal ecommerce apps”. The result was Greplr - http://greplr.github.io/greplr.com/ A year down the lane, what could have been possibly a startup, is now just an open source project on Github, with most of us busy in our personal/professional/academmic lives. But the there were many learn… more

This talk will deal with the cross-platform parts specifically of maintaing an Electron project. We’ll touch briefly on some common ground, as to how we can ship a complete server-client architecture (that you might be already hosting as a webserver + website solution) web stack into a single Electron project as a standalone, offline Desktop app. Then we’ll discuss the differences between the Lin… more

Paying via Credit/Debit cards (or NetBanking) one huge leaky cauldron on mobile apps. We have a new food delivery or clothing merchandise startup popping up every day, and those enormous discounts pull you into making purchases from them from the get go. But when you put in your payment details in your random built-in-a-month startup-level-amateurly built app, you have no clue how many people are… more

Your brand has multiple products on the web. They all need authentication. But obviously, you’d maintain a common authentication and user database. Also, in this age, you cannot make a login system without Login with [Facebook|Google|Twitter|...] For the second thing, you need to consume Oauth2.0 (the industry standard now), for the first thing, you need to make your own Oauth server. And you wan… more

This will go through the journey of building a blogging app (Medium clone) using Kotlin, Nativescript and Flutter and discuss the differences in developer and user experience for the apps built using all these platforms. more

Having built two popular Vuex plugins (vuex-module-decorators and vuex-persist), I figured there are often pieces of our app that we reuse over and over again, and building a plugin for Vue or Vuex is idea for such situations. We will take a quick look at what are the steps respectively to build a plugin for Vue itself, or it’s data library Vuex. more
