Sharing should expose the document a recipient needs, not the application's entire filesystem. FileProvider helps manage that boundary.
Evaluation approach
Limit shareable paths and grant temporary URI permissions as needed. Exclude internal databases, configuration and logs.
Application example
When sharing a PDF, check that neighboring documents remain inaccessible. Inspect permissions after cancellation.
Limits and considerations
Broad path definitions can leave excess access behind an otherwise correct sharing interface.
What remains after sharing?
Distinguish URI permission lifetime from copies made by the recipient. The application can manage its temporary grants but cannot always revoke a legitimately saved copy. Explain that consequence accurately.
Checks and decisions
- Narrow shared paths
- Justify write access
- Check post-sharing behavior
