Mostly in my experience, most of these categories of people don't really care for the empathetic viewpoint of making platforms accessible. I am from Nigeria and the Laws don't "make" us implement accessibility in applications, unlike some counties where you can get sued. Which is also a valid reason for Implementing accessibility. However, I have successfully explained to stakeholders of products that if you create a platform that is accessible you have created an opportunity to get more uses and more users === more $$$. Regardless making Accessibility important is super important. Imagine making something that everyone can use. It is brilliant.

Media accessibility has is concerned with the more visual aspect of accessibility. It focuses on what people see, understand, and uses. So using the right colors for example, so that people with visual impairments(color blindness, achromatopia, etc. ) Can navigate your platform while understanding what's going on. Essentially how the human eyes can play a role in disabilities and how we can make a better web experience. I have done a talk about this https://drive.google.com/open?id=1muu3kMdE6JK3wiIUOMTzeEAHweQ_Lf7Y . Please check it out. It offers some insight on how you can understand and implement Media Accessibility

Accessibility doesn't only apply to web development, it actually spans every aspect of life 😊. You can check this out to learn about accessibility in android development https://developer.android.com/guide/topics/ui/accessibility

I would advise starting by using semantic code In your projects, also https://webaim.org/ is a really great resource for learning more and I think there is a free course on udacity about this

Hi Bolaji, In my opinion. Implementing accessibility isn't necessarily "hard" and it is taught in the basics. When you think of it the bases of accessible apps start with semantic HTML (HTML5). I personally learned HTML5 without knowing I was learning to make accessible apps. I think maybe if that was pointed out with the importance a lot of people would be conscious about it.
