Question 1

Android permissions can be extended by
A) Using keyword "extends".
B) Creating custom permissions in manifest file.
C) Permissions cannot be extended.
D) None are correct.

Accepted Answer

Custom permissions can be created in the Android manifest file to extend the default permissions granted by the system. This allows developers to define their own custom permissions and enforce them within their app. The keyword "extends" is not used for extending permissions in Android.

Question 2

Dangerous Permissions can cause real harm or damage to user's Personal ___________.
A) Data
B) Money
C) Device
D) All choices are correct.

Accepted Answer

Dangerous permissions can lead to unauthorized access to personal data, financial loss, or harm to the device itself, making all choices correct.

Question 3

Which of the following is correct about Content providers in Android?
A) They are used to share data between devices
B) They are used to share data between applications
C) They are used to share data between applications signed with same certificate
D) Data read by content providers are deleted when application closes.

Accepted Answer

Content providers in Android are used to share data between different applications. They provide a standard interface for data access and allow data to be queried, inserted, updated, and deleted. Content providers can also be used to grant permissions to other applications to access data.

Question 4

Which of the following permissions is most dangerous and can cause severe damage to Device?
A) BRICK
B) REBOOT
C) SHUTDOWN
D) ACCESS_WIFI_STATE

Accepted Answer

The "BRICK" permission is the most dangerous as it has the ability to completely brick (render unusable) a device. This permission allows an app to access low-level system functions that can cause severe damage to the device if misused. The other options such as REBOOT and SHUTDOWN may cause inconvenience or disruption, but they do not have the potential to cause permanent damage to the device like the BRICK permission. ACCESS_WIFI_STATE is a common and harmless permission that allows an app to check the state of the device's Wi-Fi connection.

Question 5

What is the reason for using Permissions in application development?
A) To protect data and code
B) To create patent
C) To make it work better
D) Application cannot be created without permissions

Accepted Answer

Permissions are used in application development to protect data and code from unauthorized access or modification. By granting specific permissions to different users or programs, only authorized parties are able to interact with sensitive information or functionality within the application. Without permissions, the security and integrity of an application would be compromised.

Question 6

Which of the following is the only Android application component which interacts with user?
A) Activity
B) Service
C) Content Provider

Question 8

Which XML tag is used to make use of protected features of the device? A) B) C) D)

Accepted Answer

The tag is used to declare permissions that the app needs in order to access protected features of the device, such as accessing the internet, reading contacts, or using the camera. This tag must be included in the app's manifest file. The tag is used to set the minimum SDK version required by the app, while the tag is used to define the main components and attributes of the app. The tag is used to define custom permissions that the app can grant to other apps.

Question 9

Signature permission is also known as: (Choose two)
A) System Permissions or Level three permission.
B) Special situation permissions.
C) All are correct.
D) None are correct.

Accepted Answer

Signature permission is sometimes referred to as level three permission or system permission, but it can also be considered a special situation permission as it is not a standard permission granted to all users. Therefore, options A and B are both correct.

Question 10

When are permissions enforced in Activities?
A) When they launched by Context.startActivity() or Context.startActivityFor Result().
B) When method Context.enforcepermission() is called.
C) When method Context.stopActivity() is called.
D) When Context.checkPermission() is called.

Accepted Answer

Permissions are enforced in Activities when they are launched byContext.startActivity() or Context.startActivityForResult(). The system checks the app's declared permissions at this stage and determines whether to allow or deny the activity to perform the requested operation. The other options (B, C, and D) are not directly related to the enforcement of permissions in Activities.

Question 11

Signature Permissions are granted automatically if and only if?
A) Requesting application were signed with same certificate as application which declared the permission.
B) Requesting application were signed with same certificate as Android device version number.
C) Requesting application were signed with same certificate as Android system image.

Signature permissions are automatically granted if the requesting application is signed with the same certificate as the application which declared the permission.

Question 12

Which of the following is correct about application level permissions?
A) They are required to contact with Android Operating system.
B) They are required for an Application to perform its operations.
C) They are required to create an application.
D) They are automatically created.

Accepted Answer

Application level permissions are necessary for an application to perform its operations. These permissions determine what actions an application can perform, such as accessing the camera or contacts on a user's device. They are not required to create an application or contact with the Android Operating system, nor are they automatically created.

Question 13

How many level of protection are there in Permission?
A) Seven.
B) User Defined.
C) Four.
D) Depends of the Android OS version.

There are four levels of protection in Android Permission: normal, dangerous, signature, and signatureOrSystem. The number of levels is standardized and does not vary based on the Android OS version.

Question 14

Permission group is a concept of creating:
A) A group of similar permission
B) A group of all permissions in an Application
C) A group of all components in an Application
D) A group of all permissions irrespective of application

Accepted Answer

Permission groups are created to group similar permissions together, for example, all camera-related permissions can be grouped together. This makes it easier for users to understand and manage the permissions they grant to apps. It also helps developers to request permissions more clearly and concisely, reducing confusion and increasing transparency.

Question 15

Normal permissions can be converted into namespace using?
A) Permission group
B) Permission tree
C) Permission
D) Import statements

Accepted Answer

Permissions can be organized into a hierarchical structure using a permission tree. This allows for better management and organization of permissions, as well as the ability to easily apply permissions to specific parts of the code through namespace references. Permission groups and import statements may also be useful in managing permissions, but they do not specifically address the organization of permissions into namespaces.

Question 16

Service is an Android component which runs in the background to perform background task.
A) True.
B) False.
C) Depends on the situation.
D) Services is not an Android component.

Accepted Answer

This statement is true. Services are specifically designed to perform long-running operations in the background without interacting with the user interface. They can run even if the user switches to another app or leaves the app altogether.

Question 17

Permissions can be added inside
A) AndroidManifest.xml.
B) Layout.xml file
C) Res folder
D) Bin folder

Accepted Answer

Permissions must be declared in the AndroidManifest.xml file, as this is where the system looks to check the app's permissions before installation. The other options (B, C, D) do not have any connection to permissions.

Question 18

Which permission listed below is a normal permission?
A) SET_WALLPAPER
B) READ_CALENDAR
C) FACTORY_TEST
D) REBOOT

Accepted Answer

SET_WALLPAPER is a normal permission, which means it does not pose a risk to the user's privacy or the operation of other apps. Normal permissions are automatically granted by the system.

Question 19

Application can send permissions programmatically.
A) Depends on developer
B) Yes but not all times
C) No
D) Yes

Accepted Answer

Yes, applications can send permissions programmatically through the Android permission system. This allows developers to request permission from the user at runtime instead of only at the time of installation. However, it is important for developers to use this functionality responsibly and not request unnecessary permissions that could violate user privacy or security.

Question 20

What are the permissions which are granted automatically without user's approval called?
A) Signature Permissions
B) System Permissions
C) Dangerous Permissions
D) Normal Permission

Accepted Answer

Normal permissions are granted automatically by the system without requiring explicit user approval because they pose minimal risk to the user's privacy or the operation of other apps.
