Listen to changes of a file in cloud

Question

once i gained persistant access to a file in a cloud picked by the user using

Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
intent.setType("application/json");
startActivityForResult(intent, IMPORT);

and

getContentResolver().takePersistableUriPermission(uri, Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

is there a way to listen to changes made to that file outside the app? Or would i have to check it myself with some time interval? If so, can i get the last modified date without downloading the whole file?

Answer 1

is there a way to listen to changes made to that file outside the app?

No, sorry.

Or would i have to check it myself with some time interval?

Presumably yes.

If so, can i get the last modified date without downloading the whole file?

Wrap the document Uri in DocumentFile.fromSingleUri() , then call lastModified() on the DocumentFile . Note that the value of this is up to the cloud document provider and may or may not be up to date.
