NOTE: All 1st-time contributors should know Topic approval and PR submission does NOT guarantee your Topic/Article will be published. Our team of Peer Reviewers and Content Moderators will review all PRs that come in to make sure they adhere to the standard of quality we expect from the EngEd community.

We expect all community memebers to go through provided examples, resources, and previously published material before submitting content. As a rule of thumb, please only submit articles (pull requests) that are complete, formatted correctly, and include a fully polished article (ready to be published and error free).

All revisions and edits should be completed on your own forked repo (as to not take up room in the queue). Any PR that is submitted incomplete (meaning not ready to be published as is) will be closed. A PR being closed does NOT mean the article can not be published (or fixed) it simply means that the edits, revisions, and fixes will happen outside of the queue.

Building an application that requires a user to submit information requires you to verify this data before they are sent into your application. This is where the concept of form validations comes in. When a user fills in an email the application must be able to check if the user has provided an email input. If not, update the user accordingly to fill in the right email format. There are many values and specific data that an application requires from a user. This guide aims to help you understand how to achieve such concepts using the android studio. This guide will use LiveData, View model, and Data Binding to help check the inputs in real-time.

Hi @manmusa100

Could you please expand upon how your content will differ from what is already available on this article? We lean towards content that offers an original viewpoint/approach around programming-centric topics.

Hey @LinusMuema I can choose to use Binding Adapters and use Regex checks instead of using the Livedata.
