Googl has always not been friendly of cryptocurrencies in general, latest update is this: Google has placed a ban on mining apps hosted on google play store
This is how a certain news can be misinterpreted, these applications you are talking about are just fake ones and how on earth could anyone mine bitcoin with these apps and they are just fake ones and it must be blocked without a doubt as they are trying to take advantage of new users who are not aware of the technology and how it works and this news is no way anything against the crypto currency market.
