Resolving Intent Filters

When the system receives an implicit intent to start an activity, it searches for the best activity for the intent by comparing the intent to intent filters based on three aspects:

• The intent action
• The intent data (both URI and data type)
• The intent category

Ordered Intents

TODO: Why would you want to use this?

sendOrderedBroadcast()

Use the android:priority tag in <intent-filter/> to set the priority.
