Answer 1

An updated, more efficient, Kotlin version, that bypasses Bitmaps and doesn't store entire ByteArray's in memory (risking OOM errors).

fun convertImageFileToBase64(imageFile: File): String {
    return ByteArrayOutputStream().use { outputStream ->
        Base64OutputStream(outputStream, Base64.DEFAULT).use { base64FilterStream ->
            imageFile.inputStream().use { inputStream ->
                inputStream.copyTo(base64FilterStream)
            }
        }
        return@use outputStream.toString()
    }
}
