How to save the image (taken using camera) manually in Android

Question

I'd like to know how can I control when a pciture taken from camera can be saved, right now I have this code:

File storagePath = new File(Environment.
                    getExternalStorageDirectory() + "/PhotoAR/"); 
      storagePath.mkdirs(); 
   
      File myImage = new File(storagePath,
                    Long.toString(System.currentTimeMillis()) + ".jpg");
            
      try
      {
        FileOutputStream out = new FileOutputStream(myImage);
        newImage.compress(Bitmap.CompressFormat.JPEG, 80, out);


        out.flush();
        out.close();
      }
      catch(FileNotFoundException e)
      {
        Log.d("In Saving File", e + "");    
      }
      catch(IOException e)
      {
        Log.d("In Saving File", e + "");
      }

But right now, the preview isn't working, I mean, the image is saved in PhotoAR folder, but it's saved automatically, I'd like to have a button or something, and save or discard option, is there any way to improve it to accomplish this behavior?

Any example perhaps?
