Delete file from internal storage

Question

I\'m trying to delete images stored in internal storage. I\'ve come up with this so far:

File dir = getFilesDir();
File file = new File(dir, id+\".jpg\");
bo         


        

Answer 1

The getFilesDir() somehow didn't work. Using a method, which returns the entire path and filename gave the desired result. Here is the code:

File file = new File(inputHandle.getImgPath(id));
boolean deleted = file.delete();

Answer 2

Have you tried Context.deleteFile() ?

This is an old topic, but I will add my experience, maybe someone finds this helpful

2019-11-12 20:05:58.801 27764-27764/com.strba.myapplicationx I/File: content://com.strba.myapplicationx.fileprovider/my_images/JPEG_20191112_200550_4444350520538787768.jpg //same file when trying to delete it

solution1:

              Uri uriDelete=Uri.parse (adapter.getNoteAt (viewHolder.getAdapterPosition ()).getImageuri ());//getter getImageuri on my object from adapter that returns String with content uri

here I initialize Content resolver and delete it with a passed parameter of that URI

            ContentResolver contentResolver = getContentResolver ();
            contentResolver.delete (uriDelete,null ,null );

solution2(my first solution-from head in this time I do know that ): content resolver exists...

              String path = "/storage/emulated/0/Android/data/com.strba.myapplicationx/files/Readings/" +
                    adapter.getNoteAt (viewHolder.getAdapterPosition ()).getImageuri ().substring (58);

            File file = new File (path);
            if (file != null) {
                file.delete ();
            }

Hope that this will be helpful to someone happy coding

Answer 4

This works for me:

Java

File file = new File(photoPath);
file.delete();

MediaScannerConnection.scanFile(context,
                new String[]{file.toString()},
                new String[]{file.getName()},null);

Kotlin

val file = File(photoPath) 
file.delete()

MediaScannerConnection.scanFile(context, arrayOf(file.toString()),
      arrayOf(file.getName()), null)

Answer 5

Have you tried getFilesDir().getAbsolutePath()?

Seems you fixed your problem by initializing the File object with a full path. I believe this would also do the trick.

Answer 6

You can also use: file.getCanonicalFile().delete();
