how to delete an image from android when its URI is known?

Question

Im developing an android app which selects an image from the gallery in one activity and displays it in another.But when I try to delete the selected image it doesnt delete.I'm passing its uri between the two activies. Many thanks in Advance!!!!

Here's my Code :

ACTIVITY HOMESCREEN

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     super.onActivityResult(requestCode, resultCode, data);

     if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
          Uri uri = data.getData();
          Intent i = new Intent(this, Imageviewer.class);       
          i.putExtra("imgpath", uri.toString());
          startActivity(i);
     }
}

IMAGEVIEWER ACTIVITY :

Uri imageUri;
imageUri = Uri.parse(intent.getStringExtra("imgpath"));
File fdelete = new File(imageUri.toString());

    if (fdelete.exists()) {
         if (fdelete.delete()) {
               System.out.println("file Deleted :" );
         } else {
               System.out.println("file not Deleted :");
         }
    }

In the `ACTIVITY HOMESCREEN` you converted the `imgpath` to string once and then in the imgviewer activity you did the same and you get the `URI` again which is the problem..Do it like this : Get the imgPath first from URI, Convert it to string the send it to the next Activity(`IMAGEVIEWER` in your case) then there is no need to convert it or using it as `Uri`, Just retrieve the path then use it.

First you must take real path of image:

//getting real path from uri
private String getFilePath(Uri uri) {
    String[] projection = {MediaStore.Images.Media.DATA};

    Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
    if (cursor != null) {
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(projection[0]);
        String picturePath = cursor.getString(columnIndex); // returns null
        cursor.close();
        return picturePath;
    }
    return null;
}

Then you can delete this file like below:

Uri imageUri;
imageUri = Uri.parse(intent.getStringExtra("imgpath"));
File fdelete = new File(getFilePath(imageUri));

if (fdelete.exists()) {
     if (fdelete.delete()) {
           System.out.println("file Deleted :" );
     } else {
           System.out.println("file not Deleted :");
     }
}

@hkchakladar maybe you don't have correct access to read storage? If your android version is higher than 5 you must ask runtime permission from user. — Axbor Axrorov, Jun 17 '19 at 07:21

Try this : (In the second Activity) ImageViewerActivity in your case.

Intent intent = getIntent();
        String receivedPath = intent.getExtras().getString("imgpath");
        File fdelete = new File(receivedPath);

        if (fdelete.exists()) {
            if (fdelete.delete()) {
                System.out.println("file Deleted :" );
            } else {
                System.out.println("file not Deleted :");
            }
        }

Also you can debug your codes line by line to see and check if the ImgPath is getting correctly or not!

With kotlin you could do: uri.toFile().delete() and its deleted
