Android App Distribution in 2020

Play Store? Huawei AppGallery? Custom updater?

This article aims to answer common questions about the possibilities of android app distribution. I try to compare various ways of installation which can be interesting for non-public apps. I also examine relevant app stores to summarize their possibilities and limitations. The monetization, advertisement, and related business aspects are taken just briefly. Beware - the market situation is taken from the US/EU viewpoint. The regional situation in Russia, China, or India is beyond my knowledge.
