Setting a timer for a long period of time cause warning.

[ajoykarmakar]

Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info.

How to fix this warning?

Well, I guess react-native-background-timer doesn't support long timers, ie. doesn't leverage the AlarmManager solution in Android? Quite disappointing.

I'm getting another kind of warning:
