Apps Android Game Development Question

[wholt]

Hello everyone.
I've been looking around the interwebz, but unfortunately I couldn't find any thing explaining this. My question is:
Do every Android game developers use things such as LibGDX? What does professional game developers use?
An example could be - What is Geometry Dash made with? what about stick hero? etc.

Thanks!
Just to let you guys know, I do know Java.
