It moves away from the “install-time” permission model of earlier versions to a more granular, “runtime” model, giving users significantly increased control over their privacy and security.
-
Runtime Request Dialogs
Applications are required to request permissions from the user at the time a feature requiring that permission is used, rather than solely during installation. For instance, a camera application might request access to the device’s location only when the user attempts to geotag a photograph. This approach provides context and allows users to make more informed decisions about granting access.
-
Granular Control
Users gain the ability to selectively grant or deny individual permissions to applications, even after installation. If a user initially grants a social media application access to their contacts, they can later revoke that permission without uninstalling the application. This flexibility mitigates potential privacy risks and enhances user autonomy.
-
Permission Groups
Related permissions are grouped together for easier management. For example, permissions related to accessing the user’s calendar, contacts, and call logs fall under the “Contacts” group. Granting one permission within a group typically grants all permissions within that group; however, users retain the ability to revoke individual permissions within a group if desired. This balances user control with usability.
-
Impact on Application Development
Developers were required to adapt their applications to handle the new permission model, including gracefully handling scenarios where users deny permissions. This required a more robust and user-centric approach to application design, encouraging developers to clearly articulate the rationale behind permission requests and to provide alternative functionality when permissions are not granted.

App Linking aimed to resolve this ambiguity by enabling direct opening of web URLs within corresponding applications.
-
Automatic Verification
This operating system introduced automatic verification of app links. When an application declares its association with a specific website, the system attempts to verify this relationship by checking a Digital Asset Links file hosted on the corresponding web domain. This automated process minimizes user intervention and enhances security by ensuring that only legitimate applications can handle specific web URLs. For instance, tapping a Twitter link on a device would directly open the Twitter application, bypassing any intermediate selection prompts, provided the application and website relationship has been successfully verified.
-
Intent Filter Configuration
Developers configure intent filters within their applications to declare the web URLs they are capable of handling. These filters specify the scheme (e.g., “http” or “https”), host, and path prefixes that the application can process. Accurate and meticulous configuration of these intent filters is crucial for the correct operation of App Linking. An example would be an e-commerce application specifying an intent filter for product pages on its website. When a user clicks a link to a specific product, the application directly opens to that product page.
-
Security Implications
The verification process associated with App Linking enhances security by reducing the potential for malicious applications to intercept web traffic intended for legitimate applications. By verifying the association between the application and the website, the system mitigates the risk of phishing attacks and other forms of URL spoofing. If verification fails, the system falls back to the traditional disambiguation dialog, ensuring the user maintains control over the application that handles the web link.
-
User Experience Enhancement
App Linking provides a more fluid and intuitive user experience by eliminating unnecessary steps in the process of opening web links. Users are seamlessly directed to the relevant content within the appropriate application, reducing friction and improving overall satisfaction.
