                    Log.i(TAG, "Success")

If rename() returns false then which of the three was false? Wrong coding. Do the checks before you calll renameTo then you know what happens. — blackapps, Sep 14 '22 at 18:18
It does not make sense to check of the parent exists. Checking if the file exists is very good. But do it outside your function. — blackapps, Sep 14 '22 at 18:20

renameTO() doesn't work in my environment. The solution is to skip the temporary file method alltogeher, since it doesn't seem to be possible to solve in any reasonable time frame.

so i suggest not use File.renameTo() method in Internal Storage environment. Renaming a file in this environment, can do: - Copy content of the old file to new file. - Delete old file. :)

I really don't know how to delete the file. Please share code to handle my question. Thank bro ! – Xuân Đức Nguyễn Sep 14 '22 at 04:45
This is code for delete File dir = getFilesDir(); File file = new File(dir, "filename"); boolean deleted = file.delete(); – SAVAN JADAV Sep 14 '22 at 05:05
RenameTo works just fine as long as both paths are in the same mount point. It only becomes a problem when renaming and moving between internal and external storage. – Gabe Sechan Sep 14 '22 at 05:08
