If you are using Kotlin and Glide in your app then this is for you:

Glide.with(this)
                .asBitmap()
                .load(imageURL)
                .into(object : SimpleTarget(1920, 1080) {
                    override fun onResourceReady(bitmap: Bitmap, transition: Transition?) {
                        saveImage(bitmap)
                    }
                })

and this is that function

internal fun saveImage(image: Bitmap) {
    val savedImagePath: String

    val imageFileName = System.currentTimeMillis().toString() + ".jpg"
    val storageDir = File(Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES).toString() + "/Folder Name")
    var success = true
    if (!storageDir.exists()) {
        success = storageDir.mkdirs()
    }
    if (success) {
        val imageFile = File(storageDir, imageFileName)
        savedImagePath = imageFile.absolutePath
        try {
            val fOut = FileOutputStream(imageFile)
            image.compress(Bitmap.CompressFormat.JPEG, 100, fOut)
            fOut.close()
        } catch (e: Exception) {
            e.printStackTrace()
        }

        galleryAddPic(savedImagePath)
    }
}


private fun galleryAddPic(imagePath: String) {
    val mediaScanIntent = Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE)
    val f = File(imagePath)
    val contentUri = FileProvider.getUriForFile(applicationContext, packageName, f)
    mediaScanIntent.data = contentUri
    sendBroadcast(mediaScanIntent)
}

galleryAddPic() is used to see the image in a phone gallery.

Note: now if you face file uri exception then this can help you.
