I'm building an app that:
Create An object that have a field for Image
pick an Image from device storage "Gallery"
store that object into room database
show the data with the Image from database
when I try to pick the second I click the Image I got this Error
No persistable permission grants found for UID "number" and Uri content://media/...
This is my code Block for picking the Image:
val singlePhotoPickerLauncher = rememberLauncherForActivityResult(
contract = ActivityResultContracts.PickVisualMedia()){ imageUri ->
if (imageUri != null){
val contentResolver = context.contentResolver
val takeFlags: Int = Intent.FLAG_GRANT_READ_URI_PERMISSION or
Intent.FLAG_GRANT_WRITE_URI_PERMISSION
try {
contentResolver.takePersistableUriPermission(imageUri, takeFlags)
viewModel.onEvent(AddPlantEvents.AddImageUri(imageUri))
} catch (e: SecurityException) {
// Handle the SecurityException, e.g., show an error message
Log.e("PickVisualMedia", "Failed to take persistable permission", e)
}
}
}
this is my Button :
Button(
modifier = Modifier
.width(100.dp)
.height(100.dp),
onClick = {
singlePhotoPickerLauncher.launch(PickVisualMediaRequest(ActivityResultContracts.PickVisualMedia.ImageOnly))
}) {
Text(
text = "Add Photo",
textAlign = TextAlign.Center,
fontSize = 19.sp)
}
at First I didn't add ContentResolver and got a different Error then I searched and asked, and found out I need it to get a persist Uri, when I edited my code and launch the app to test it I got the error as mentioned above "No persistable permission grants found for UID and Uri"
I did not found an answer using the same method I use to get the Images so I'm asking now to find solution or If I need to change the way I get Images.
P.S: I found out why I did not get persist uri: I removed this flag:
or Intent.FLAG_GRANT_WRITE_URI_PERMISSION
and the the code works
The only contract that is (almost) guaranteed to offer a persistable permission grant is OpenDocument
. PickVisualMedia
may fall back to OpenDocument
on some devices, but on those where it does not, you are not guaranteed to get a persistable permission grant.
Your options are:
Switch to OpenDocument
, or
Stick with PickVisualMedia
, but deal gracefully when your takePersistableUriPermission()
fails
