i have download activity in app, users can download content. activity called main activity, , retrieves list of available files download on network. to avoid fetching whole list again when download activity recreated e.g. because of rotation, override onsaveinstancestate() store list in bundle , evaluate bundle passed oncreate() method. works rotation. however, able implement same behavior if user hits , later returns download activity. android in case not call onsaveinstancestate() , hence nothing gets saved. my idea override onbackpressed() , include call onsaveinstancestate() . will work @ all? can onsaveinstancestate(new bundle()) , or have initialize new bundle somehow? will android store bundle , pass oncreate() next instance of activity creates, or have take care myself of storing bundle , passing new instance (if so, how)? update: simply adding @override public void onbackpressed() { onsaveinstancestate(new bundle()); super.onbackpressed(); ...

when should use file , when should use string filename constructor? constructed method should contain contents of file. can choose: public graphmodel(file file) throws ioexception { this(); readfromfile(file); } versus public graphmodel(string filename) throws ioexception { this(); readfromfile(new file(filename)); } is 1 preferred on other? some people think matter of taste / personal preference ... or doesn't matter. argue matter. lets assume api's implementation require file internally. then, there 3 alternative approaches: // #1 public graphmodel(file file) throws ioexception {...} // #2 public graphmodel(string file) throws ioexception {...} // #3 public graphmodel(file file) throws ioexception {...} public graphmodel(string file) throws ioexception { this(new file(file)); } now compare these apis in various contexts: if adopt approach #1, , caller has filename string must construct file . potenti...
