I've got this task to do: "Create an Android Project with Android Studio. For each Android Activity Lifecycle Methods, instead of just Logging(Log.i etc), show a Toast Message." but I never used Android Studio before, could someone of you just show me an example how to do something like this?
You can search for a good tutorial on the web.
Here is video lessons how to install Android Studio and build first application.
And here is the official text instruction from Google.
