Understanding the Math Equation of a Circle Before we jump to the code, let's get a small lesson on how are circles represented in a polar coordinate system. Imagine a circle with a radius r at the Origin. The circle's center can be depicted as (0,0) and (0,r) is a point on the circle. Another way to represent this point on the circle would be ?=? sin ?, ?= ? cos ? Here ? is the angle in radians. Now that we know how to represent a point on the circle, let's translate this into some Kotlin code. Writing the Code fun printPointOnTheCircle(thetaInDegrees: Float, radius: Float, cX: Float, cY ..read more

Introduction The Per-App Language Preferences is one of the latest additions to Android 13. What does this mean? For instance, if the default language of your phone is English. You can set Hindi as a language for an app and Spanish as another. This saves the hassle of changing languages back and forth on your device.

In this article, you'll learn how to use Dagger for conditionally provisioning (providing) your dependencies without adding stress to your memory. As your product grows. You often start trying out new things with it. Since we don't always know what'll work best for the users, we often try multiple strategies to solve a problem. This is done through some sort of an A/B test. However, this comes at a cost. The cost is that two distinct solutions exist in the same version of the app, to solve one customer pain point. Let's try to see it through a lens of an image editing application. Introducing ..read more

Introduction Wanted to connect my Android side project to Kite Connect API (Stock Broker). The authentication mechanism to obtain an access token looks like this. Since I don't have a web server I decided to use Firebase Cloud Functions to handle the redirect for the request token and exchange it for an access token that can be returned to the client. Let's get some configurations out of the way before we start writing the code. Prerequisites Kite Connect 3 Account Firebase Account This article assumes an intermediate familiarity with npm, Javascript, Kotlin, Firebase and Android. Kite Con ..read more

In this hands on tutorial, you will learn how to implement discord login on android using openID AppAuth SDK. Introduction to OAuth OAuth refers to an open standard for access delegation. Most of the applications now use it as a way to authenticate users into their platform. It takes away the need for users to have an identity on each app and instead allows them to use one identity in multiple places. Technically speaking, the OAuth flow, in its simplest form, is only a bunch of network requests executed in a certain order with some specific parameters. Based on what happens during the flow ..read more

Understanding Our Small Problem I was writing a small python script to push make some requests to an endpoint for seeding my database. I had my data in a json file so it was as simple as reading the json array and making a POST request with each JSON object. Now while writing my function to convert the json event into the request Payload, I just copy pasted the Json object and made necessary changes, however python wasn’t happy about the “” to be used as the keys for my dictionary. So what I ..read more
