A very simple solution is to add a string resource like this.

res/values/strings.xml

Day

res/values-night/strings.xml

Night

And then wherever you need to check it:

if (resources.getString(R.string.mode) == "Day") {
    // Do Day stuff here
} else {
    // Do night stuff here
}

But you CAN NOT call this before super.onCreate() in an activity's life-cycle. It will always return "Day" before onCreate.
