this camera movement on onresume

if(map != null && northeast != null && southwest != null){         map.animatecamera(cameraupdatefactory.newlatlngbounds(new latlngbounds(southwest,northeast),10));     }else if(map != null && centerpoint != null){         cameraposition position = new cameraposition.builder()          .target(centerpoint).zoom(17).build();         map.animatecamera(cameraupdatefactory.newcameraposition(position));     }

if take out camera movement not crash not go point of moved away or something.

i check make sure map not null not know causing error?

caused by: java.lang.illegalstateexception: map size should not 0. likely, layout has not yet occured map view.

this should clear enough. cannot call

map.animatecamera(cameraupdatefactory.newlatlngbounds(new latlngbounds(southwest,northeast),10));

before layout complete. need use 3 param version instead.

see documentation here: newlatlngbounds

aternatively may listen layout complete instead of calling code in onresume.

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.
