How to save bitmap in custom gallery?

Question

I have understood that I can create a folder in DCIM and if there is a file in it, the dir is displayed as an album name. I can create the dir just fine, in this case, I call the dir "ThoughtCast."

I try saving a PNG file, however, and it does not appear.

Here is my code:

   public void savebitmap(Bitmap bmp) throws IOException {

        String file_path =Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + File.separator + "ThoughtCast/";

        File dir = new File(file_path);
        if(!dir.exists())
            dir.mkdirs();
        File file = new File(dir, "sketchpad"  + ".png");
        FileOutputStream fOut = new FileOutputStream(file);

        bmp.compress(Bitmap.CompressFormat.PNG, 85, fOut);
        fOut.flush();
        fOut.close();

    }

Any help will be appreciated. Thanks

Try this it may help you (it's in kotlin)

I am currently do this task

 private fun saveImage(bitmap: Bitmap) {
    var outStream: FileOutputStream? = null
    // Write to SD Card
    try {
        val dir = File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + File.separator + "ThoughtCast/")
        dir.mkdirs()
        val fileName = String.format("%s_%d.jpg", "Image", System.currentTimeMillis())
        val outFile = File(dir, fileName)
        outStream = FileOutputStream(outFile)
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream)
        outStream.flush()
        outStream.close()
        Utils.showSnackBar(binding.rootView, getString(R.string.image_saved))
    } catch (e: FileNotFoundException) {
        Crashlytics.logException(e)
    } catch (e: IOException) {
        Crashlytics.logException(e)
    } finally {
    }
}
