问题 I need to send images and small video files (around 5MB, less than 10MB) to a REST service, which I will write. I am wondering whether I should use Byte[] or Stream to accomplish this task. What would be the dividing line in terms of transfer file size between using Byte[] and Stream? 回答1: The amount of free memory you're willing to commit to the transaction is your only real constraint. If you have a 5M file, then you'll need to load the entire thing in to RAM, which will cost 5M. If you

It's not the @login_required decorator that comes with Django, but it's almost the same thing, except that allows access only to users from certain groups. This works as intended. Also, I'm serving media (user uploaded) files with Apache, like this: Alias /media /path/to/media <Directory /path/to/media> Require all granted </Directory I

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . In Android, we can use the mediaplayer to play songs on the device, and cursors to get the track information (which the OS keeps track of). My question is, what are the Java equivalents of these?

问题 My service extends the MediaBrowserService class and it responds to certain MediaController actions such as getMediaController().getTransportControls().onPlay() . However, I didn't find a way to "control" my service from a Widget, because the MediaController class isn't available from it.
