I have an EditText to input a web link. I want to preview the inputted URL, similar to the function in Facebook, where we post a link and will see an image of the page, with the title on top and URL at the bottom.
How can I develop this in Android?

Facebook link preview is basically the way your link will appear on Facebook when published. A line of text vs. title, description and image. There were times when anyone could edit link previews on Facebook which Facebook eventually banned in 2017, in hopes to stop people from using this feature with bad intentions.
An app or social media platform downloads the link content and generates the preview. The receiving app then shows the preview. It doesn't need to open the link, so potentially malicious content hosted on the linked website doesn't reach the user right away.
Link previews offer a peek at content such as web pages or documents in many messaging apps. The feature allows users to see a short summary and preview image inline with the rest of the conversation without having to tap on the link.
You can find the cross icon at the top-right corner of the post preview. Click the cross icon, and the link metadata preview will be removed. The post preview will update to show what the Facebook post will look like when published.
Use JSOUP after the user enters a link in the editext to parse out your links OG meta tags (this is what FB looks at) scrape out the meta tags:
Here is an example of the meta info you want from a recent nytimes article
