Suggested Answer

The suggested answer is B.

The findViewById(int id) method is the correct method to retrieve a reference to a view using the id attribute in an Android resource XML.

Question 3 of 228
Which of the following is not an Android component (i.e. a point from which the system can enter your application)?
Answer

Suggested Answer

The suggested answer is C.

The four main types of Android components are Activities, Services, Content Providers, and Broadcast Receivers. These components are crucial entry points for the system and applications to interact with each other. A Layout, on the other hand, is not an entry point; it is a resource defining the UI structure of an interface. Therefore, Layout is not considered an Android component through which the system can enter your application.

Question 5 of 228
Which configuration file holds the permission to use the internet?
Answer

Suggested Answer

The suggested answer is D.

The configuration file that holds the permission to use the internet is the Manifest file. In Android development, the AndroidManifest.xml file is used to declare permissions like INTERNET, which are necessary for the app to access the internet. Layout files, property files, and Java source files do not serve the function of declaring application permissions.
