QUESTION 5

(a) In relation to permissions, explain the purpose of the manifest file and describe how it used at install time. Explain what happens when an application tries to use a permission that it has,as well as when an application tries to use a permission that it does not have.

(b) You are presented with an application that produces exceptions stating that the ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION permissions were not granted. Summarise the possible causes of this and state the changes you would make to the application to ensure these exceptions did not appear.

c) Whitelisting is arguably more secure than blacklisting and therefore, a generally better approach to security. Discuss.
