android - Send SMS only once from BroadcastReceiver -


i saw commonwares locationpoller demo here github.com/commonsguy/cwac-locpoll/

here in locationreceiver checking whether location in specified area or not. if not in area send text message(sms) phone number.

but sendind text messages(sms) continuously receives new location @ every specific interval. defined class varible flag=0 (initally)

            public class locationreceiver extends broadcastreceiver {                 int flag=0;             public void onreceive(context context, intent intent) {              ............               if( flag==0)    //center of campus                        {                           checkarea(loc,"500","22.599669","72.820473","5556","your ward out of college campus");                           toast.maketext(context, "you have moved out",toast.length_short);                           flag=1;                       }                 }             }

but not working, still sends sms continuously. should ?

save unix timestamp when send message using sharedpreferences next time broadcast fired check existance of said timestamp. you'd send message if timestamp not exist or old enough (actual time - saved timestamp >= threshshold define), updating or creating timestamp when send message.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
