How to save a photo by creating a file with another name instead of replacing the previous file?

Question

Hello, good afternoon! I’m having trouble saving the photo, because when you save it replaces, instead of creating another with another name:

The problem is in on-click Istener button btnAbrir:

// TimeStamp: 20210728_165608
String TimeStamp = new SimpleDateFormat("yyyyMMDdd_HHmmss").format(new Date());

// ImageFile: JPEG_20210728_165200_
String ImageFile = "JPEG_" + TimeStamp + "_";

// picsDir: File('/Pictures')
File picsDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);

// imageFile: File('/Pictures/.jpg')
File imageFile = new File(picsDir, ".jpg");

That is, the value of ImageFile is being ignored. To fix this, just add it when creating the file:

// TimeStamp: 20210728_165200
String TimeStamp = new SimpleDateFormat("yyyyMMDdd_HHmmss").format(new Date());

// ImageFile: JPEG_20210728_165200.jpg
String ImageFile = "JPEG_" + TimeStamp + ".jpg";

// picsDir: File('/Pictures')
File picsDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);

// imageFile: File('/Pictures/JPEG_20210728_165200.jpg')
File imageFile = new File(picsDir, ImageFile);
