Here is my Code
val launcher1 = rememberLauncherForActivityResult(contract =
ActivityResultContracts.GetContent()) { uri: Uri? ->
imageUri1 = uri
}
And I must give to ViewModel Like this
fun deviceComplete(deviceId: Int?, file:File?) = viewModelScope.launch{
}
How to convert this uri to File ..?? I'm really don't know
This example for image Uri to File
Application.instance - this instance from Singleton Application Class
@Suppress("DEPRECATION")
fun Uri.asFile(): File? {
Application.instance.contentResolver
.query(this, arrayOf(MediaStore.Images.Media.DATA), null, null, null)
?.use { cursor ->
cursor.moveToFirst()
val cursorData =
cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA))
return if (cursorData == null) {
returnCursorData(this)?.let { File(it) }
} else {
File(cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA)))
}
}
return null
}
@Suppress("DEPRECATION")
private fun returnCursorData(uri: Uri?): String? {
val context = Application.instance
if (DocumentsContract.isDocumentUri(context, uri)) {
val wholeID = DocumentsContract.getDocumentId(uri)
val splits = wholeID.split(":".toRegex()).toTypedArray()
if (splits.size == 2) {
val id = splits[1]
val column = arrayOf(MediaStore.Images.Media.DATA)
val sel = MediaStore.Images.Media._ID + "=?"
val cursor: Cursor? = context.contentResolver.query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, arrayOf(id), null
)
val columnIndex: Int? = cursor?.getColumnIndex(column[0])
if (cursor?.moveToFirst() == true) {
return columnIndex?.let { cursor.getString(it) }
}
cursor?.close()
}
} else {
return uri?.path
}
return null
}
did you request permission first?
You can achieve that with
val state = rememberPermissionState(permission = Manifest.permission.READ_EXTERNAL_STORAGE
