How much performance does it costs to broadcast intents?
Is it okay to broadcast multiple per second or are intents expensive?
Intents are meant to launch different activities within the Android OS or to inform about basic actions. It seems like a bad design pattern to use them otherwise. As they travel between different processes and therefore implement the Parcelable interface, they are not the most light-weight.
If you are looking to update different activities at the same time you might consider using a common service.
According to this blog post, intents are 10 times slower than direct function calls
