Answer 1

I believe only the framework has access to this sort of information; Android applications are largely unaware of each other and unable to determine what else is happening on the system.

However, as Android is based on Linux, it may be possible to glean some amount of information outside of the Android application framework by running the ps (process list) command on the device.

Each process running on the system is identified by its package name. But the presence of an item in the process list does not necessarily imply usage. For example, background services would show an application as running even if there is no user interaction. Similarly, an APK can contain multiple logical applications under the same package name.

Answer 2

There's an app I have on my phone called spare parts that shows exactly that information (under 'usage statistics') so it's definitely possible.
