Then your app would be compiled, so the Downloaded event would work. You could then use the notifier progress dialog when the download starts and when the event is fired to finish. But the device should give a notification "ding" in any case.
Okay so I have a question when I downloaded a file aix it still didn't put it in my folder.
It said it in my notifications that I got it but not in my file
What is the path to download files to the chromebook downlaods directory? I have tried: /download /Download /Downloads /sdcard/Download /storage/emulated/0/Downloads
@TIMAI2 says that there is a file on a chromebook called Playfiles which I am guessing the downloads go too. (I have no idea if this is right because I have not checked it out yet.)
I have not said that. I have said that there is a directory in the Files app called Play Files. Also in Files there is a directory called Downloads, which is where downloaded files in the companion end up, on a Chromebook.
Please take the time to read the advice, given, properly, to avoid further confusion.
I haved looked and didn't see it on play files
Because it is not in the play files!
May you please tell me where the file that the mit app companion sends the downloads because I locate it
