android - How to not stop surface view while taking picture -

-

i take multi picture , i'm using these codes. makes screen freeze (after stop , start preview) in short time , make users uncomfortable. how can resolve problem. attention.

picturecallback jpegcallback = new picturecallback() {         public void onpicturetaken(byte[] data, camera camera) {             cpreview.mcamera.startpreview();             fileoutputstream outstream = null;             /*try {                  outstream = new fileoutputstream(string.format(                         "/sdcard/camtest/%d.jpg", system.currenttimemillis()));                 outstream.write(data);                 outstream.close();              } catch (filenotfoundexception e) {                 e.printstacktrace();             } catch (ioexception e) {                 e.printstacktrace();             } {             }*/          }     };

if there no way, i'm thinking of recording video , convert images ( though waste more time).

some of latest phones nexus 4, samsung galaxy s5 etc support camera parameter called "zsl" (zero shutter lag).

in regular image capture sequence, camera hal stops preview , takes picture. when parameter set, preview not stopped while capturing picture. , image captured comparatively faster. since preview not stopped not see above problem , don't have call start preview in picture callback.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
