[davidjiagoogle]

As titled. Any implementations of such ImagePostProcessor likely needs access to the contentResolver that is used during the image capture process. Adding it as an input parameter to processImage()

Summary of Changes

Hello @davidjiagoogle, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant enhancement to the image post-processing pipeline by providing ContentResolver access directly within the ImagePostProcessor interface. This change enables more robust and flexible post-processing capabilities, as implementations can now interact with the Android MediaStore or other content providers to manage image data effectively after capture.

Highlights

• ImagePostProcessor Interface Update: The ImagePostProcessor interface has been updated to include a ContentResolver parameter in its postProcessImage method. This allows any implementation of the interface to access the ContentResolver during image post-processing.
• ContentResolver Injection: The CameraXCameraSystem now passes the contentResolver instance to the postProcessImage method of all registered ImagePostProcessor implementations, ensuring they have the necessary context for their operations.

Code Review

This pull request adds a ContentResolver parameter to the ImagePostProcessor.processImage() method, which is a reasonable change to provide more context to post-processing logic. However, this change introduces a build-breaking issue in the test suite by not updating a fake implementation of the modified interface. Additionally, the documentation for the changed method is now out of date. My review includes comments to address these critical and medium-severity issues.

[gemini-code-assist]

This change to the ImagePostProcessor interface breaks the test implementation in core/camera/src/androidTest/java/com/google/jetpackcamera/core/camera/CameraXCameraSystemTest.kt. The FakeImagePostProcessor class must be updated to match the new method signature, otherwise the build will fail.

Please update FakeImagePostProcessor.postProcessImage to:

override suspend fun postProcessImage(uri: Uri, contentResolver: ContentResolver) { /* ... */ }

1. The style guide directs to analyze existing test files relevant to the code being changed, even if not modified in the PR, to ensure no new logic is left uncovered or broken. This change breaks an existing test implementation. ^(link)

[gemini-code-assist]

The KDoc for postProcessImage is now out of sync with its signature. Please add documentation for the new contentResolver parameter to keep the documentation accurate.

Example:

 * @param contentResolver The [ContentResolver] to use for processing the image.
