java - Error while debugging an Android Widget -

-

i have android widget application. application this page (i downloaded source code).
debugging widget user this tutorial. put 1 breakpoint in code (provided below).

public static void pushwidgetupdate(context context, remoteviews remoteviews) { log.d("message", "fortunately, have come point");  componentname mywidget = new componentname(context, mywidgetprovider.class); //breakpoint here! appwidgetmanager manager = appwidgetmanager.getinstance(context); manager.updateappwidget(mywidget, remoteviews);      }

when begin debugging process, green debugging line shown on line breakpoint usual. after several seconds disappears, , see widget (or debugging process, or process on phone itself) has been terminated. process no more in process list in ddms perspective.
why debugger stop?

i have read on stackoverflow, debugging android apps better via logging (log.d(string tag, string log_text). so, have not found reason of error, started debug via logging.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
