Select image and upload to server android

Question

I want to upload the image to server by selecting from gallery

Opening gallery by

val pickPhoto = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
        startForResult.launch(pickPhoto)

And then activity result

val startForResult = registerForActivityResult(ActivityResultContracts.StartActivityForResult())
{ result: ActivityResult ->
    if (result.resultCode == Activity.RESULT_OK) {
        //  you will get result here in result.data
        if(result.data!=null){
            val f=File(result.data.toString())
            println(f.absolutePath)
        }
    }

}

However I think the file is not correct.

My api call is like

@Multipart
@PUT
fun uploadFile(
    @Url url:String,
    @Part("file") name: RequestBody,
    @Part filepart: MultipartBody.Part
): Response<String>

And I am calling this as

val fileToUpload: MultipartBody.Part =
            MultipartBody.Part.createFormData("file", file.getName())
        val filename: RequestBody =
            file.getName().toRequestBody("text/plain".toMediaTypeOrNull())
        Api.uploadFile(uploadUrl,filename,fileToUpload) 

Its a stream upload

Issue was due to URI only as it was not getting the correct absolute path of file

to retrive the absolute path

private fun getRealPathFromURI(contentURI: Uri): String {
    val result: String
    val cursor: Cursor? = requireContext().contentResolver.query(contentURI, null, null, null, null)
    if (cursor == null) {
        result = contentURI.getPath().toString()
    } else {
        cursor.moveToFirst()
        val idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA)
        result = cursor.getString(idx)
        cursor.close()
    }
    return result
}

The activity result

val startForResult = registerForActivityResult(ActivityResultContracts.StartActivityForResult())
{ result: ActivityResult ->
    if (result.resultCode == Activity.RESULT_OK) {
        //  you will get result here in result.data
        if(result.data!=null){
            val f=File(getRealPathFromURI(result.data?.data!!))
            viewModel.uploadCheque(f)
        }
    }

}
