Question

What all system events are made public / shared and are accessible from within my android app ? e.g.

Events shared by other applications : new email received, calender meeting started etc,

Events shared by system : system going to be rebooted, a processes taking lot of CPU etc.

Can you point me any blogs/documentation in this regard ?

Thanks

You need to learn about Intents.

You fire an Intent to another app to request it to do something for you

You can also listen for global events (text messages received, bluetooth turned on etc):
