The algorithm used in finding out which apps are inactive, is that the device recognises which apps have not been active in the background or been triggered by the user in a while.
Android's Accessibility Services has been widely used by app developers to create apps that are better suited for users with disabilities.
According to Google, all apps that fail to meet its requirements within 30 days will be removed from Play Store.
Several other developers have told us they received this email, and there is a Reddit thread full of additional reports. "Your app must comply with our Permissions policy and the Prominent Disclosure requirements of our User Data policy", Google's message reads. Google states that developers can alternatively remove the request for accessibility services within the app, or can choose to unpublish their app. Google is doing this for security reasons as it does not want developers to use the API for purposes other than to help users with disabilities.
There are of course apps that you can download to help check which apps are vampires, draining your phone of blood (battery). "Serious or repeated violations of any nature will result in the termination of your developer account, and investigation and possible termination of related Google accounts", Google said. This is a huge change as it does affect the functionality of apps, with some apps potentially losing the ability to function as they might rely too heavily on the API. That is because even apps designed specifically for disabled people can be banned because anyone can use them. New applications are getting larger in size and while devices with 64GB of storage may not think twice about installing an app over 100MB, those with lower-end devices and limited storage could find their smartphones running out of space. Is an app like AutoInput (an app that helps a lot of disabled folks) not allowed because a lot of non-disabled people can benefit from it too?
The developers of Google has completed the process of modernization of the Android operating system 8.1 Oreo.
