android - Dynamically setting SENDER_ID in GCM -


i trying set project sender id dynamically fetching server throws invalid sender id exception. fetching sender id server in base application class make sure before application launches , have overrided getsenderids() method in gcmintentservice. 

    public gcmintentservice() {           super();     }      @override     protected string[] getsenderids(context context) {          string[] ids = new string[1];          ids[0] = sender_id;          return ids;     }

but getting invalid sender id exception. i'd appreciate if 1 give me informed opinion on how set sender id dynammically server.

ok managed self. i'll try explain it. so, firstly edited getsenderids() method this: 

     @override     protected string[] getsenderids(context context) {              updatesenderidtask(context);             string[] ids = new string[1];             ids[0] = getsenderid(context);             return ids;     }

previously had set ids[0] variable sender_id set inside updatesenderidtask method. invalid sender id exception thrown because gcm access sender_id variable before updatesenderidtask method executed though had called inside base application class. so, called updatesendertask inside getsenderids overrided method make sure fetch id server before gcm uses it. double check it, set ids[0] local method getsenderid. here implementation it: 

    static string getsenderid(context context) {              customsharedprefs prefs = customsharedprefs.getinstance(context);             if (prefs.getstring(constants.sender_id).equals("0")                     || prefs.getstring(constants.sender_id) == null) {                 updatesenderidtask(context);             }             log.e("returned sender_id", prefs.getstring(constants.sender_id));             return prefs.getstring(constants.sender_id);  }

the updatesenderidtask method fetches id server , stores in shared preference variable.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
