I tried looking for an answer but I couldn't find any.
I have a simple TinyMCE text editor that stores data into a MySQL database and then displays it on the website.
I would like to know if it is possible to display that text in and Android app using exactly the same formatting.
I'm not sure what you do you means by "display that text in an Android app".
I've just scanned the TinyMCE text editor you mentioned. Look like it is a library created for web application only. So If you want to integrate it as a mobile native component - aka View, the answer is No.
But in mobile development, we have a thing called WebView. both Android and Ios have it. Basically, it is a mini version of a browser. So you could have a web page that contains your TinyMCE text editor. Next, create a mobile application that has a WebView. Then present your web page on that WebView.
According to this doc, you must add some tag to present the editor on mobile. https://www.tiny.cloud/docs/mobile/
