A PendingIntent can let another party initiate limited work on your application's behalf. The breadth of its target and mutable data determines the authority being delegated.
Evaluation approach
Prefer immutable, explicitly targeted structures where possible. Protect transferred data and invocation context. Verify Android-version-specific requirements in official documentation.
Application example
For a financial screen opened from a notification, check that intent values match the previously approved operation.
Limits and considerations
Reaching the apparently correct screen does not establish that the underlying authority is properly constrained.
Constrain delegated authority
PendingIntent can allow another component to trigger a particular operation on the application's behalf later. It is therefore more than a transport object. Mutability and target selection affect the scope of the authority granted.
Test stale or reused requests in sensitive flows opened through notifications. When the user changes accounts, an earlier intent must not apply to the wrong account. Verify operating-system and target-SDK behavior under the actual distribution conditions.
Checks and decisions
- Specify the target explicitly
- Justify mutability
- Test reuse
Review flags, destination and account context together.
