Merge Risk: 🔵 Low · up to 546c6

A quick save can produce a card missing its background or logo, and a failed save gives no confirmation. Users can retry, so these are bounded risks, but the save flow should address them or explicitly accept them before merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 546c6

The export is initiated by the user and uses Android’s storage controls. No unauthorized export path was identified. Interrupted saves have limited application-level recovery, however, and device-specific cleanup behavior remains unverified.

Retained concerns

  • Low · reliability · inferred: The new shared-media transaction retains its inserted URI only in the running save operation and performs rollback through an exception handler. Process termination after insertion can bypass that cleanup, leaving unfinished gallery state without an application-level reconciliation path in the new flow. API 26–28 also lacks the pending-publication stage used on newer devices. The duration and visibility of remnants depend on platform behavior; permanent leakage is not established.
Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is user-selected export of displayed card content into the device’s external image collection. The saver creates a new URI and targets that URI for writing and failure deletion; it does not select an existing image for modification. Gallery consumers remain subject to platform access rules.

Trust Boundaries and Controls

  • observed — On API 28 and below, the handler requires existing WRITE_EXTERNAL_STORAGE permission or a granted request before invoking the save callback. Denial does not invoke persistence. API 29+ takes the permission-free MediaStore branch, and the manifest caps legacy permission at API 28.

Resilience and Maintainability Implications

  • inferred — Cancellation propagation is preserved by the coroutine helper, but it is not an export-rollback guarantee. The IO transaction has no explicit cancellation check between insertion and publication, so cancellation may be reported after the blocking write has completed. Concurrent requests create separate transactions rather than sharing one mutable image URI.

Hardening Proposals

  • proposed — Define whether requested exports should complete after navigation and how interrupted exports reach a terminal state. If application-level reconciliation is required, track only app-created unfinished items and account for Android’s automatic pending-item cleanup and legacy storage behavior before adding recovery logic.

Coil 3.3.0 SubcomposeAsyncImage source default loading state no loading callback placeholder behavior GitHub

💡 Result:

**Coil 3.3.0 source:** [`SubcomposeAsyncImage.kt`](https://github.com/coil-kt/coil/blob/3.3.0/coil-compose-core/src/commonMain/kotlin/coil3/compose/SubcomposeAsyncImage.kt)

- `loading` is an optional **composable** for replacing what’s drawn during loading; `onLoading` is a separate optional **callback** invoked when loading begins. Both default to `null`. ([github.com](https://github.com/coil-kt/coil/blob/3.3.0/coil-compose-core/src/commonMain/kotlin/coil3/compose/SubcomposeAsyncImage.kt))
- With no `loading` composable, the loading-state branch falls through to `SubcomposeAsyncImageContent()`. So Coil does **not** automatically draw a separate placeholder composable here; it draws the painter’s content. ([github.com](https://github.com/coil-kt/coil/blob/3.3.0/coil-compose-core/src/commonMain/kotlin/coil3/compose/SubcomposeAsyncImage.kt))
- To show custom loading UI, provide `loading = { ... }`. Or set a request placeholder painter and use `SubcomposeAsyncImageContent()` in that branch if you want the painter rendered there.

That behavior follows from the v3.3.0 source’s `contentOf` implementation; the source doesn’t label it as a built-in “placeholder behavior.” ([github.com](https://github.com/coil-kt/coil/blob/3.3.0/coil-compose-core/src/commonMain/kotlin/coil3/compose/SubcomposeAsyncImage.kt))

Coil 3.3.0 AsyncImagePainter loading state no placeholder painter null draw source State.Loading placeholder null

💡 Result:

In **Coil 3.3.0**, `AsyncImagePainter.State.Loading` carries a nullable painter: `State.Loading(val painter: Painter?)`. If it is `null`, there’s no placeholder painter to draw, so the image area remains blank while loading—this is expected, not necessarily a loading failure. The 3.3.0 changelog also notes a change in Coil 3’s Compose behavior: `AsyncImagePainter` executes the request rather than defaulting to `ImageRequest.placeholder`. ([coil-kt.github.io](https://coil-kt.github.io/coil/api/coil-compose-core/coil3.compose/-async-image-painter/-state/-loading/index.html?utm_source=openai))

To show something during loading, provide a placeholder painter to `AsyncImage`/`rememberAsyncImagePainter`, or render your own loading UI by observing the state. If you’re using `rememberAsyncImagePainter`, note that its state starts as `Empty` on the first composition. ([github.com](https://github.com/coil-kt/coil/blob/main/coil-compose/README.md?utm_source=openai))

The API page found is for a newer snapshot, not specifically 3.3.0; the 3.3.0 changelog confirms the version-specific behavior, but does not document the nullable `Loading.painter` detail.

Coil 3.3.0 AsyncImagePainter.kt GitHub tag State.Loading painter nullable placeholder null onDraw Painter implementation

💡 Result:

In Coil **3.3.0**, `AsyncImagePainter.State.Loading` accepts a nullable painter: its `painter` property is `Painter?`. During request startup, the `onStart` callback converts the request’s placeholder to a painter; if there is no placeholder, it updates the state to `Loading(null)`. ([raw.githubusercontent.com](https://raw.githubusercontent.com/coil-kt/coil/3.3.0/coil-compose-core/src/commonMain/kotlin/coil3/compose/AsyncImagePainter.kt))

`AsyncImagePainter` itself extends Compose’s `Painter`. Its `onDraw` records the draw size, then draws its current internal painter only if non-null (`painter?.apply { draw(...) }`). Thus a null painter means this draw method draws nothing; it doesn’t create or draw a separate fallback painter. ([raw.githubusercontent.com](https://raw.githubusercontent.com/coil-kt/coil/3.3.0/coil-compose-core/src/commonMain/kotlin/coil3/compose/AsyncImagePainter.kt))

This is the **3.3.0 tag**, not an inference from the latest API. ([github.com](https://github.com/coil-kt/coil/blob/3.3.0/coil-compose-core/src/commonMain/kotlin/coil3/compose/AsyncImagePainter.kt))

배경과 로고가 모두 로드된 뒤에 저장을 허용하세요.

저장 버튼은 항상 활성화되어 있습니다. UrlImage에는 로딩 중 표시할 placeholder가 없으므로, 아직 로드되지 않은 이미지는 그려지지 않습니다. 버튼을 누르면 현재 graphicsLayer를 비트맵으로 캡처해 갤러리에 저장합니다. 로딩 중 저장하면 배경이나 로고가 빠진 카드가 저장될 수 있습니다. 두 이미지가 모두 로드될 때까지 저장을 비활성화하세요.

호출부에서는 먼저 권한이 거부됐을 때의 로직을 정해두고

val storagePermission = rememberGalleryStoragePermissionHandler(
    onDenied = viewModel::onSavePermissionDenied,
)

권한 승인 후 저장 버튼을 클릭할 때 실제 실행할 작업을 넘겨주는 방식으로 사용하고 있습니다!

onSaveClick = { bitmap ->
    storagePermission { viewModel.savePassCardImage(bitmap) }
}

이렇게 구현한 이유는 rememberLauncherForActivityResult는 composable 함수여서 onclick 내부에서 호출이 안돼요! 그래서 핸들러 내부에서 권한 관련된 로직을 관리하고 호출부에서는 권한이 승인된 이후 실행할 작업만 넘겨줄 수 있도록 구현했습니당

이게 편의성을 고려해서 구현한 건 아니라.. 답변이 되었을 지는 잘 모르겠네요..ㅎㅎ😅

p3: onDenied를 바로 쓰지 않고 rememberUpdatedState로 감싸신 이유가 궁금해요! 이런 식으로 쓰는 건 처음 봐서, 어떤 상황을 대비해서 쓰신 건지 알려주시면 배워가겠습니다ㅎㅎ

rememberUpdatedState는 리컴포지션 이후에도 기존에 캡쳐해둔 람다를 사용하는 것을 방지하고 항상 최신 람다를 참조하게 해줍니다.
권한 요청이 비동기로 처리되다보니 그 사이 발생할 리컴포지션에 대비해 실행할 람다를 최신 상태로 계속 유지하기 위해 사용했는데... 찾아보니 rememberLauncherForActivityResult가 이미 내부적으로 rememberUpdatedState를 사용하고 있더라구요! 여기서는 없어도 될 것 같아요ㅎㅎ 제거해두겠습니다!

p3: png라 quality 값이 무시되는데 100은 필수 인자라서 넣어두신 건가욤?? 이런 경우엔 보통 값을 100을 넣는 편인지 문득 궁금해서 여쭤봅니다!

맞아요! 필수 인자라 넣어뒀습니다. jpeg나 webp와 같은 포맷은 해당 값으로 변환할 이미지의 품질을 지정하는데 0~100이라 크게 생각 안하고 제일 높은 값으로 넣어뒀습니당..ㅎㅎ 혹시 포맷이 바뀌더라도 이미지 품질을 계속 유지할 수도 있을 것 같네용

p2: 배경 이미지랑 로고는 네트워크를 통해서 받아오는데 저장버튼을 바로 누를 수 있는상태네욤! 네트워크가 느릴때 로딩이 끝나기 전에 누르면 이미지 없이 캡처될 수도 있을거같은데 그 부분 괜찮은지 우려됩니닷 ㅠㅠ
