Action required: If you aren't already doing so, you must explain to users how your app is using the 'android.permission.BIND_ACCESSIBILITY_SERVICE' to help users with disabilities use Android devices and apps. Once the beta version of the app leaked out, Google itself turned the closed beta into public beta to get feedback from a larger audience. Revelations on Twitter show that the new version of Android will warn you which of your apps is using up more battery and how. We also should mention that developers are using the API to create nefarious apps.
A bunch of handy apps on Android that let you do things like autofill passwords, copy content to your clipboard, and automate tasks, may soon no longer work on your mobile device because Google is changing the rules for accessing its platform's Accessibility Services, reports Android Police. "Your app must comply with our Permissions policy and the Prominent Disclosure requirements of our User Data policy", Google's message reads.
There are of course apps that you can download to help check which apps are vampires, draining your phone of blood (battery). Google states that developers can alternatively remove the request for accessibility services within the app, or can choose to unpublish their app. "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. Developers have 30 days to address their use of Accessibility Services so we will have to wait and see what happens. If notifications are the ones that are draining your battery you can easily disable them and continue to use your application. This is what has concerned Google and this is also why they have sent emails to developers.
For example, in the case of Tile, one can turn off the location (which, however, defeats the objective of the app) to save battery if it is running in the background.
