MEDIA_PROJECTION_SERVICE

• New screen capture functionality (permission flow, virtual display, image processing) lacks unit or instrumentation tests. Consider adding tests to cover success and failure paths.

package com.linkedin.android.shaky;

The field 'pendingDataCollectionCallback' is declared but never used. Consider removing it or implementing its intended usage to avoid dead code.

Suggested change

private CollectDataTask.Callback pendingDataCollectionCallback = null;

The 'parent' attribute is empty, which will break style inheritance at runtime. Specify a valid parent style (e.g., a ShapeAppearance material component).

Suggested change

	<style name="CustomShapeAppearanceBottomSheetDialog" parent="">
	<style name="CustomShapeAppearanceBottomSheetDialog" parent="ShapeAppearance.MaterialComponents">

[nitpick] You register an OnGlobalLayoutListener without removing it after the first callback, which can lead to repeated invocations or memory leaks. Remove the listener once layout is complete.

Suggested change

	view.getViewTreeObserver().addOnGlobalLayoutListener(() -> {
	// Get the parent view of the bottom sheet
	View bottomSheet = (View) view.getParent();
	// Set up the bottom sheet behavior
	BottomSheetBehavior<View> behavior = BottomSheetBehavior.from(bottomSheet);
	// Set the height to 50% of screen
	behavior.setPeekHeight(getResources().getDisplayMetrics().heightPixels / 2);
	behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
	view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
	@Override
	public void onGlobalLayout() {
	// Get the parent view of the bottom sheet
	View bottomSheet = (View) view.getParent();
	// Set up the bottom sheet behavior
	BottomSheetBehavior<View> behavior = BottomSheetBehavior.from(bottomSheet);
	// Set the height to 50% of screen
	behavior.setPeekHeight(getResources().getDisplayMetrics().heightPixels / 2);
	behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
	// Remove the listener to prevent repeated invocations
	view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
	}

[nitpick] Hardcoded notification text should be moved to string resources for localization support.
