how to show progress while uploading files

[sanket]

Use async tasks

[Dean Djermanović]

@sanket AsyncTasks are deprecated. @san How are you uploading files?

[san]

i used retrofit lib to upload files as multipart

[san]

now i want to show the progress ,so how to implement that

[Dean Djermanović]

You can create a custom RequestBody that will emit progress. Here’s how I did this in my project:

class ProgressEmittingRequestBody(
    private val mediaType: String,
    private val file: File,
    private val onProgressUpdate: (Int) -> Unit
) : RequestBody() {

    override fun contentType(): MediaType? = MediaType.parse(mediaType)

    override fun contentLength(): Long = file.length()

    override fun writeTo(sink: BufferedSink) {

        val inputStream = FileInputStream(file)
        val buffer = ByteArray(BUFFER_SIZE)
        var uploaded: Long = 0
        val fileSize = file.length()

        try {
            while (true) {

                val read = inputStream.read(buffer)
                if (read == -1) break

                uploaded += read
                sink.write(buffer, 0, read)

                val progress = (((uploaded / fileSize.toDouble())) * 100).toInt()
                onProgressUpdate(progress)
            }
        } catch (e: Exception) {
            Timber.e(e)
        } finally {
            inputStream.close()
        }
    }

    companion object {
        const val BUFFER_SIZE = 1024
    }
}

ok

how to show progress if i upload multiple files

[Dean Djermanović]

In that case you’ll observe each progress independently. What’s your concern exactly?

[san]

in this code your passing file as a parameter but I'm having uri only

[san]

so how to do with the uri or how can i get the file from uri
