I have an array of specified hours for each day, when brightness should by changed for application which is awake 24/7. It happens twice a day.
What I want to achieve is to find the most economical way of implementation that problem.
Should I use AlarmManager or maybe there is a better sollution?
Activity is always awake...
Finally, I decided to use an AlarmManager with BroadcastReceiver setting value in SharedPreferences and then in Activity I have a Handler which checks that value.
