abelonogov-ld · 2025-11-19T20:04:42Z

Summary

Support ldMask() for Native and Compose views.
a. Native

  view.ldMask()

b. Compose

 modifier = Modifier.ldMask()

2 XML screens: Fruta and Credit Card
Make Compose User form rotate

How did you test this change?

Test SR using RRWeb player on SecondaryActivity, Fruta(XML), Credit Card

Note

Adds ldMask for native Views and Compose, introduces SensitiveAreasCollector to mask captured regions, and includes new Credit Card and Smoothie sample screens.

SDK / Session Replay:
- Masking API: Add View.ldMask()/ldUnmask() and Modifier.ldMask()/ldUnmask() in MaskingViewAPI.kt; define LdMaskSemanticsKey.
- Sensitive Area Detection: Introduce SensitiveAreasCollector to gather sensitive rects from Compose semantics and native View tags; add view_tags.xml ids.
- Capture Pipeline: Refactor CaptureSource to use SensitiveAreasCollector and apply gray masking over returned rects.
E2E App:
- New Screens (XML): Add CreditCardActivity and SmoothieListActivity with layouts (activity_credit_card.xml, activity_smoothie_list.xml, item_smoothie.xml) and SmoothieAdapter; register in AndroidManifest.xml and add launch buttons in MainActivity.
- Compose Demo: Update SecondaryActivity to use Modifier.ldMask() on header and animate rotation of the address card.
- UI/Dependencies: Switch theme to Theme.Material3.DayNight.NoActionBar; add androidx.recyclerview:recyclerview dependency.

I did a high level review and don't have any concerns. Due to my bandwidth constraints, I think @agrognetti will have to be primary reviewer.

looks reasonable to me!

This package should be inside com.example.androidobservability (The whole code of the app goes there - unless you use different modules, which is not the case)

+    <item name = "ld_mask_tag" type="id"/>

This is the correct formatting when writing resources

Suggested change

<item name = "ld_mask_tag" type="id"/>

<item name = "ld_unmask_tag" type="id"/>

<item name="ld_mask_tag" type="id" />

<item name="ld_unmask_tag" type="id" />

Can I add local.properties into .gitignore? @agrognetti

Wouldn't be better to at least log the exceptions? Here and in the other "catch" blocks
