Answer)
Q10. The following is NOT a reason that connectivity can be
lost:
A. The operating system
The operating system cannot be a reason simply for the connectivity problem or the loss in connectivity.
Q11. To reduce an app's drain on the battery, the app should do
:
C. Shut down all activity when an app is paused.
The app drain on the battery should be checked, and the app should shut down and turn off the activity when the application is paused.
Q12. If desired sensor accuracy cannot be attained immediately,
then the app should be designed to:
B. Let the user continue working with the app, but inform the user
of progress toward achieving the desired level of accuracy.
The app should let the user work when the desired sensor accuracy cannot be obtained, and thus we should inform the user for the progress and for achieving the level of the accuracy which should be desired.
Q13. When running app if a hardware button is pressed on either
platform:
B. The app moves from the running state to another state.
The app will move from the running state to some other state when the hardware button is pressed on the platform, as using this mode the app will stop all the active tasks which are running on the screen.
