Detecting Currently running App. Android -


i using following code detect running app . when running new app. not getting it's package name, toasting "com.hedy.launcher". whats wrong code ? 

 @override           public int onstartcommand(intent intent,int flags, int startid) {                 // todo auto-generated method stub                 super.onstartcommand(intent, flags,startid);                 toast.maketext(this, "service running", toast.length_short).show();                  handler = new handler(){                      @override                     public void handlemessage(message msg)                      {                         // todo auto-generated method stub                         super.handlemessage(msg);                        // count=count+1;                        // toast.maketext(myservice.this, ""+count, toast.length_short).show();                         activitymanager = (activitymanager) getapplicationcontext().getsystemservice(activity.activity_service);                         string packagename = am.getrunningtasks(1).get(0).topactivity.getpackagename();                         toast.maketext(myservice.this, ""+packagename, toast.length_short).show();                     }                  };                    new thread(new runnable(){                     public void run() {                     // todo auto-generated method stub                     while(true)                     {                        try {                         thread.sleep(1000);                         handler.sendemptymessage(0);                      } catch (interruptedexception e) {                         // todo auto-generated catch block                         e.printstacktrace();                     }                       }                                      }                 }).start();                 return 0;             } 

string packagename = am.getrunningtasks(1).get(0).topactivity.getpackagename();

this line extracting package name. try increase maxnum parameter(you have set 1).

am.getrunningtasks(maxnum) return arraylist. check contents of arraylist see whether getting required item in of them

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
