AndroidSavedStateDelegate

Android implementation of SavedStateDelegate using SavedStateHandle.

What is SavedStateHandle?

• Part of Android's ViewModel architecture

• Automatically persists data across process death

• Survives configuration changes (rotation, etc.)

• Backed by Bundle (same mechanism as onSaveInstanceState)

How Process Death Recovery Works:

1. User opens permission dialog

2. Android kills process to reclaim memory

3. SavedStateHandle automatically saves GrantHandler state

4. User returns to app

5. Android recreates process

6. SavedStateHandle restores state

7. Dialog reappears with same content

Usage:

class MyViewModel(
    private val grantManager: GrantManager,
    private val savedStateHandle: SavedStateHandle // Injected by ViewModel
) : ViewModel() {
    val cameraGrant = GrantHandler(
        grantManager = grantManager,
        grant = AppGrant.CAMERA,
        scope = viewModelScope,
        savedStateDelegate = AndroidSavedStateDelegate(savedStateHandle)
    )
}

Benefits:

• Zero boilerplate for users

• Automatic state restoration

• Works with Jetpack Compose + Navigation

• Type-safe with SavedStateHandle
