When using an implicit intent, what process does the system use to know what to do with it?
Answer(s): A
When using implicit intents, given such an arbitrary intent we need to know what to do with it. This is handled by the process of Intent resolution, which maps an Intent to an Activity, BroadcastReceiver, or Service (or sometimes two or more activities/receivers) that can handle it.The intent resolution mechanism basically revolves around matching an Intent against all of the <intent-filter> descriptions in the installed application packages.

Which of the following is NOT true about the MenuItem interface?
Answer(s): C
Both an icon and text can be displayed.The <item> element supports several attributes you can use to define an item's appearance and behavior. The items in the above menu include the following attributes:android:idA resource ID that's unique to the item, which allows the application to recognize the item when the user selects it.android:iconA reference to a drawable to use as the item's icon. android:titleA reference to a string to use as the item's title. Incorrect:B: Adding Menu Items Based on an IntentSometimes you'll want a menu item to launch an activity using an Intent (whether it's an activity in your application or another application). When you know the intent you want to use and have a specific menu item that should initiate the intent, you can execute the intent with startActivity() during the appropriate on-itemselected callback method (such as the onOptionsItemSelected() callback).However, if you are not certain that the user's device contains an application that handles the intent, then adding a menu item that invokes it can result in a non-functioning menu item, because the intent might not resolve to an activity. To solve this, Android lets you dynamically add menu items to your menu when Android finds activities on the device that handle your intent.
