The capture is a window snapshot, so it shows what the device actually rendered — Compose content, classic Views, and anything a native module drew.
Annotation tools
| Tool | Draws |
|---|---|
pen | Freehand. Five colours, three thicknesses. |
highlighter | Translucent freehand. |
rect · ellipse | Outlined shapes for circling a control. |
arrow | Points at the thing that broke. |
text | A label. Three sizes. |
redact | Draws a blur-kind shape — see below. |
pointer | Select, move and resize existing marks. |
The palette and sizes are identical across every TraceItX SDK, so a report looks the same whichever platform filed it.
Redaction is baked, not overlaid
A redact shape is rendered opaque into the image bytes before upload — not
stored as a region for a viewer to honour. The pixels underneath are gone by the
time the report leaves the device.
An overlay is a request; a bake is a guarantee. If a user blurs their bank balance, no receiver and no support engineer can recover it, because it was never uploaded.
The same applies to sensitive views — Modifier.txSensitive(),
TXSensitiveView, markSensitive() and password fields — painted black before
the screenshot leaves the capture step. See Sensitive content.
In the envelope
kind | What it is |
|---|---|
screenshot | The capture as taken. |
annotated-screenshot | The baked result, with drawings and redactions applied. |
Plus payload.annotations and payload.redactions recording the vector shapes.
A dashboard can re-render annotations over the clean screenshot — but only
annotations. Redactions cannot be undone, by design.
What comes back blank
Anything drawn on a SurfaceView — video players, camera previews, some map
views — comes back black. The capture is a PixelCopy of the window, and a
surface is composited outside it — which is why a screenshot of a video player
often shows the chrome but not the frame. A window with FLAG_SECURE set comes
back black as well.
If your whole app sets FLAG_SECURE for security reasons, screenshots will be
empty everywhere. The rest of the report — breadcrumbs, logs, network,
replay — still works, and is usually enough.
