Is there a callback function after executing permissionState.launchPermissionRequest()
in the Accompanist Permissions library? I want to execute some code only after it finishes.
CodePudding user response:
I'm copying this example from their guide:
val cameraPermissionState = rememberPermissionState(
android.Manifest.permission.CAMERA
)
when (cameraPermissionState.status) {
// If the camera permission is granted, then show screen with the feature enabled
PermissionStatus.Granted -> {
Text("Camera permission Granted")
}
is PermissionStatus.Denied -> {
Column {
val textToShow = if (cameraPermissionState.status.shouldShowRationale) {
// If the user has denied the permission but the rationale can be shown,
// then gently explain why the app requires this permission
"The camera is important for this app. Please grant the permission."
} else {
// If it's the first time the user lands on this feature, or the user
// doesn't want to be asked again for this permission, explain that the
// permission is required
"Camera permission required for this feature to be available. "
"Please grant the permission"
}
Text(textToShow)
Button(onClick = { cameraPermissionState.launchPermissionRequest() }) {
Text("Request permission")
}
}
}
}
The 2 callbacks are: PermissionStatus.Granted
and PermissionStatus.Denied
