Competent people, please, clarity.
First, how run app on Android? it happens consistently the situation when I did not run, and taskmanager they glow(and completely "left", like for example Facebook-a).
Second, if the application is running, whether it consumes the battery — and, accordingly, whether to force complete(through the task Manager) all applications not needed at the moment?
