Android settings

When switching to a new version, difficulties began with the installation (SDK) and everything else. In principle, I settled everything myself, but the project never compiles. Drawing a conclusion from the videos from YouTube, I realized that the problem is in the incorrectly installed Android from (UE4.25 / Engine / Extrax / Android). But when you try to reinstall it, it says that it was not found (repositories).
And again I did everything according to the guides, but no, now nothing is happening. No error messages, no text missing. Please help with this problem.
PS. I’m from Ukraine so sorry for the lame English
