What is the best way to write android apps?

Question

Python

I came up with the idea of ​​writing an application for Android, I know python at a good level (+/-), but I found little information on the kivy framework and basically all the information is mostly scattered over the Internet and most of the information is on English-language resources. Also, I found a lot of information on writing applications in java and a lot of training videos, books, etc.
The question is: which is better to focus on, kivy or Java?
