Error after converting android.net.Uri to java.io.File

Question

I am trying to write logic to upload an image, using Retrofit2 and Jetpack Compose. When creating a File object from the image's Uri, the File object seems to have content:// scheme instead of file://, which is causing FileNotFoundException while creating the request object for Retrofit2.

For example, the below code throws IllegalStateException.

fun upload(imageUri: Uri) {
    val file = File(imageUri.path!!)
    if (!file.exists()) {
        throw IllegalStateException("File $imageUri does not exist.")
    }
    ...
}

The exception is as below:

java.lang.IllegalStateException: File content://media/external/images/media/1000000363 does not exist

Note that the Uri is valid, and I'm able to use it to display the image in the UI.

I have tried creating the File object in different ways, such as imageUri.toFile(), which throws:

java.lang.IllegalArgumentException: Uri lacks 'file' scheme: content://media/external/images/media/1000000364

Thanks in advance!
