How do I delete a file using it's path on Android 7?

Question

I have a file on a memory card with path: /storage/7AB3-1EEF/EXTERNAL_eicar-tf.com

With the File class, I can read it, but I can't delete it.

So, how do I delete the file using only the real path to it? My code works if file stored in /storage/0/[file]

Permissions written in manifest:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The code fully works on Android 4.2.2

I tried converting the file to a URI and deleting it, but I've got an "unknown URL" error message.

Uri ur = Uri.fromFile(new File(reports.get(getAdapterPosition()).getPath()));
context.getContentResolver().delete(ur, null, null);

My button's code:

button_Delete_File.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) { 
                    File file = new File(reports.get(getAdapterPosition()).getPath()); //Here comes out the described path...
                    file.delete();
                    Log.e("File deleted?", reports.get(getAdapterPosition()).getPath());
                    if (!file.exists()) {
                        Log.e("Yes", reports.get(getAdapterPosition()).getPath());
                    } else {
                        Log.e("No", reports.get(getAdapterPosition()).getPath());
                        Toast.makeText(context, context.getResources().getString(R.string.delete_file_error), Toast.LENGTH_SHORT).show();
                    }
                }
            });

I did it! Thanks for Mr. CommonsWare's point about Storage Access Framework I was able to rework my code:

button_Delete_File.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) { //Remove item from list and delete assigned file.
       if (Build.VERSION.SDK_INT >= 19) {
           try {
               Uri uri = Uri.parse(reports.get(getAdapterPosition()).getPath());
               ContentResolver contentResolver = context.getContentResolver();
               contentResolver.takePersistableUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
               DocumentsContract.deleteDocument(contentResolver, uri);
               reports.remove(getAdapterPosition());
               notifyItemRemoved(getAdapterPosition());
           } catch (FileNotFoundException e) {
               Toast.makeText(context, context.getResources().getString(R.string.delete_file_not_found), Toast.LENGTH_SHORT).show();
           }
       } else {
           File file = new File(reports.get(getAdapterPosition()).getPath());
           file.delete();
           if (!file.exists()) {
               reports.remove(getAdapterPosition());
               notifyItemRemoved(getAdapterPosition());
           } else {
               Toast.makeText(context, context.getResources().getString(R.string.delete_file_error), Toast.LENGTH_SHORT).show();
           }
       }
   }
});

Now it works on Android 4.2.2 and 7.0.
