Disabling AppNap from java
I think Im having problems with AppNap with my application, although it is difficult to understand when/if it is kicking in. 'The correct way to disable App Nap is to use the -[NSProcessInfo beginActivityWithOptions:reason:] and -[NSProcessInfo endActivity] APIs within your app via JNI, and only when your app is actually doing work.' - Mike Swingler Has anything been done to disable AppNap from java without having to use JNI Paul

Re: Disabling AppNap from java
I've resisted posting this until now as it will probably just confuse the issue, but on this page you can find code which calls Objective C using both Rococoa and plain old JNI so you can compare and contrast. Of course the problem this is solving has nothing to do with AppNap and so it might be more distracting than anything else: http://pixel.recoil.org/code/rococoa/ Unfortunately like most things this is a matter of experience. Having done this before I could probably knock something up in a couple of hours that would meet your needs. But if it's your first time it'll be trickier for you.

However, it is based on C interfaces and calling conventions. Rococoa ( https://code.google.com/p/rococoa/) implements a similar thing for interacting with Objective-C interfaces. Scott

Re: Disabling AppNap from java
For doing simple Objective-C things like this, I wrote an objective-c bridge. It uses JNA and allows you to access any OS X SDK without having to generate stub classes for them (like you do with rococoa). https://github.com/shannah/Java-Objective-C-Bridge Some sample code to give you an idea: WebView : https://github.com/shannah/Java-Objective-C-Bridge/blob/master/java/test/ca/weblite/objc/TestWebView.java NSOpenPanel : https://github.com/shannah/Java-Objective-C-Bridge/blob/master/java/test/ca/weblite/objc/NSOpenPanelSample.java Loading a nib file: https://github.com/shannah/Java-Objective-C-Bridge/blob/master/java/test/ca/weblite/objc/LoadNibSample.java Steve On Sat, Feb 22, 2014 at 4:53 PM, Michael Hall mik3h...@gmail.com wrote: On Feb 22, 2014, at 6:23 PM, Scott Palmer swpal...@gmail.com wrote: On Sat, Feb 22, 2014 at 4:49 PM, Paul Taylor paul_t...@fastmail.fm wrote: On 22/02/2014 20:43, Eirik Bakke wrote: JNA might be a simpler way to call native functions: https://github.com/twall/jna ...
