Google banned cryptocurrency mining Android apps from the Android Play Store, following in Apple's footsteps.
The company continues to allow mining as long as the processing takes place in the cloud, but on-device mining on Android hardware is no longer allowed, CNET sister site ZDNet reports.
"We don't allow apps that mine cryptocurrency on devices. We permit apps that remotely manage the mining of cryptocurrency," it wrote in the updated Google Play developer program policies.
Google's move -- first noted by Android Police -- follows to ban cryptocurrency mining on both iOS devices and Mac in June.
Google noted that this new policy is consistent with the industry's approach.
Cryptocurrencies such as bitcoin can be "mined" by using multiple devices to solve complex mathematical problems that lock and unlock information in the blockchain, with rewards coming as each transaction is secured.
Mining requires a huge amount of processing power, so people have been investing inand using vast networks of devices.
