__Notifications__
2 types of notifications, "Toast" messages, and Notifications at the status bar / drawer.
The second allowes for custom Notifications, with custom views, custom sounds, Autocancel or not, and the possibility for a "PendingIntent" that gets fired when the user clicks on the notification at the drawer. (See last part of the video, or the project ''NotificationStatusBarWithCustomView''.
__BroadcastReceiver__
Base class for components that :
* wait for and receive events
* process and react to these events
BroadcastReceiver register the events (Intents) they are interested in.
When an intent is being broadcast, the BroadcastReceiver gets it via it's ''onReceive()'' method.
Typical use case:
* register BroadcastReceivers
* Broadcast an Intent
* Android delivers the Intent to registered recipients
* BroadcastReceivers get (onReceive() ) and handle the Intent
Registering can be
* statically via AndroidManifest.xml ( <receiver> and <intent-filter> elements ) => ''android:name'' specifies the classname of the receiver, ''android:permission'' declares the permission that is required for a sender application to broadcast this intent.
* dynamically with code (''registerReceive()''), can be in 2 scopes: LocalBroadcastManager (this application) or Context (any application)
When sending a Broadcast Intent, you can specify a permission that Receivers should have in order to get the Intent .
Event Broadcast:
* __Normal__ - processing order undefined
* __Ordered__ - sequential processing in priority order
And:
* __Sticky__ -
* __Non-Sticky__ -
