feat: process GutenbergKit media uploads per the app's media settings by dcalhoun · Pull Request #23142 · wordpress-mobile/WordPress-Android

Description

Ref CMM-1249.

Device media picked in the GutenbergKit editor (the new, experimental block editor / NBE) currently uploads raw from the WebView straight to the WordPress REST API, bypassing the app's media settings that the legacy editor honors (image optimization/resizing, quality, EXIF location stripping, video optimization).

This PR integrates GutenbergKit's new MediaUploadDelegate (from GutenbergKit#357) so device uploads are processed natively per the app's media settings before upload, mirroring WordPress-iOS#25824. GutenbergKit runs a localhost relay server while the editor is open, hands each staged file to processFile, uploads via its default uploader, and relays WordPress's raw response to the editor verbatim — so attachment objects, media_details.sizes, blob-preview replacement, save-locking and error notices all behave exactly like a direct upload.

What `GBKMediaUploadProcessor.processFile` does (mirrors the iOS decision table, adapted to Android's pipeline)

Images — optimized via the existing WPMediaUtils.getOptimizedMedia (max dimension + quality from App Settings), with GPS EXIF stripped when the "Remove location" setting is on. The reported mime type/filename is corrected to the actual output format (non-PNG inputs, including HEIC, re-encode to JPEG). When processing would be a no-op (optimization off, no strip, no rotation), the original passes through untouched — no needless lossy re-encode.
Sideways-captured images — physically rotated for self-hosted sites when optimization is off (WP.com rotates server-side; parity with legacy, #5737).
GIFs — always pass through to preserve animation.
Videos — the free-plan 5-minute duration limit is always enforced; transcoding runs (via the existing WPVideoUtils/m4m path) only when the "Optimize videos" setting is on, keeping the transcoded file only when it's smaller than the original. Transcodes are serialized to bound codec/memory pressure. This matches Android's legacy behavior (where video optimization is opt-in), rather than iOS's always-transcode.
File types disallowed by the site plan (e.g. audio on free WP.com plans) are rejected up front with a localized message relayed to the editor as a notice.

The delegate is set unconditionally for the post/page GutenbergKit editor. If GutenbergKit's upload server fails to start, uploads degrade to the existing WebView path unchanged.

Testing instructions

All in the GutenbergKit editor (enable the experimental block editor for the site). Change settings between runs in App Settings → Media.

Image optimization:

With "Optimize images" on, insert a photo wider than the max-size setting (e.g. > 2000px).

Uploaded image is resized to the configured max dimension and is a JPEG.

Turn "Optimize images" off and "Remove location" off; insert a photo.

Uploaded bytes are identical to the original (no re-encode).

Location stripping:
3. Insert a JPEG, PNG, or WebP photo with GPS EXIF, with "Remove location" on (try both with optimization on and off).

The uploaded file has no GPS EXIF.

GIF:
4. Insert an animated GIF.

It uploads unchanged and still animates.

Video:
5. With "Optimize videos" on, insert a video wider than the width setting.

Uploaded video is a transcoded MP4 at the configured width.

Turn "Optimize videos" off; insert a video.

The original video uploads.

Disallowed type:

On a free WP.com site, insert a video or audio.

The editor shows a localized notice that the file type is disallowed.

Consumes the snapshot build of wordpress-mobile/GutenbergKit#357, which adds the MediaUploadDelegate API for host-side media upload processing. To be swapped to a tagged release before merge. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Adds video optimization and strip-image-location accessors to AppPrefsWrapper, and a stripImageLocation passthrough to MediaUtilsWrapper, so the upcoming GutenbergKit media upload processor can read settings and strip GPS EXIF through injectable, testable wrappers. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Implements GutenbergKit's MediaUploadDelegate to process device media picked in the experimental block editor before upload, honoring the app's media settings the same way the legacy editor pipeline does: - Images are optimized per the max size/quality settings via WPMediaUtils.getOptimizedMedia, with GPS EXIF stripped when the strip-location setting is on, and the reported mime type/extension corrected to the actual output format (non-PNG inputs, including HEIC, re-encode to JPEG). - When processing would be a no-op, the original file passes through untouched, avoiding a needless lossy re-encode. - Sideways-captured images are rotated for self-hosted sites when optimization is off (WP.com rotates server-side; issue #5737). - GIFs always pass through to preserve animation. - Videos enforce the free-plan 5-minute duration limit and transcode via WPVideoUtils/m4m only when the optimize-video setting is on, keeping the transcoded file only when smaller than the original. Transcodes are serialized to bound codec/memory pressure. - File types disallowed by the site plan are rejected with a localized message relayed to the editor as a notice. Nothing wires the processor yet; that lands separately. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Adds JVM unit tests for the processor's decision table: optimized image output with corrected mime/extension (incl. HEIC to JPEG and PNG passthrough), no-op short-circuit, GPS stripping onto the optimized output and onto a copy when optimization is off, GIF passthrough, self-hosted orientation fix, plan-disallowed type and over-limit video rejections with localized messages, video passthrough when optimization is disabled, and same-path optimization results treated as unprocessed. Also adds a File-based isProhibitedVideoDuration overload to MediaUtilsWrapper so the processor avoids Uri.fromFile, keeping it testable on the JVM. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Sets the media upload delegate on GutenbergView so device media picked in the experimental block editor is processed per the app's media settings before upload. The fragment stores and forwards the delegate following the existing setNetworkRequestListener pattern (GutenbergView tolerates assignment before or after page load), and the activity constructs the processor with its SiteModel and injected wrappers. If GutenbergKit's upload server fails to start, uploads degrade to the existing WebView path unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Consumes the PR-build snapshot of WordPress-Utils-Android#156, which stops ImageUtils.getImageOrientation from logging a spurious "Volume data not found" error on every optimized upload staged in the app cache dir (GutenbergKit native media uploads). To be swapped to a tagged release once that PR merges. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

EXIF_MIME_TYPES gated the copy-and-strip branch on formats that can carry GPS, but androidx ExifInterface.saveAttributes() can only rewrite JPEG, PNG, and WebP. The set omitted PNG (so location-bearing PNGs uploaded un-stripped, a regression vs. the legacy pipeline) and included HEIC/HEIF (where saveAttributes throws an IOException that stripLocation swallows, uploading a still-geotagged copy while appearing to honor the setting). Correct the set to {JPEG, PNG, WebP} and cover the PNG-stripped and HEIC-passthrough cases in the decision-table tests. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

transcodeVideo logs each caught exception via .message, so Detekt's SwallowedException never fires — only TooGenericExceptionCaught does (NullPointerException and Exception are both on its generic-names list). Trim the suppression to the rule that actually triggers. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

GutenbergKit validates uploads in the WebView against the site's allowedMimeTypes (fetched from /wp-block-editor/v1/settings and cached on disk) before the request reaches this delegate, so it rejects most disallowed types with its own localized message first. Document that this app-side check is a fallback for the cache-miss/undefined-settings path and can over-reject when its static MimeTypes table is stricter than the server's cached list.
