I am storing images in SQLiteCipher as a blob (byte[] form):

    public void insertNewImageBlob (byte[] image, String password) {
        System.out.println(image);
        SQLiteDatabase db = instance.getWritableDatabase(password);
        ContentValues values = new ContentValues();
        values.put(COLUMN_IMAGE, image);
        db.insert(TABLE_NAME,null,values);
        db.close();
    }

The table has nothing just a list of byte array, no ids or anything. Insertion is good, RecyclerView shows all the images from the database, now then the user clicks on the image, i want the one to be deleted. So, user clicks an image and I send the image to deleteImage method to delete it from the database.

Here is the code trying me to Delete a single image:

    public void deleteImage (String password, byte[] image) {
        SQLiteDatabase db = instance.getWritableDatabase(password);
        ContentValues values = new ContentValues();
        values.put(COLUMN_IMAGE,image);
        db.delete(TABLE_NAME,COLUMN_IMAGE+"='"+ image +"'",null);
        db.close();
    }

But it does not delete the image from the database.
