Android - SendBroadcast Overhead

Question

How significant is sendBroadcast ? This is something bothering me if I plan to call him often.

Answer 1

It depends on the number of recipients. If your application is the only one who receives it, you should not worry. A TIME_TICK broadcast TIME_TICK sent every minute by the system, and the phone’s battery lasts more than a week for 100% inactivity.
