permissions - Android - dynamically request camera access -

-

i want add following permissions android app, doing block 500 devices supported in current build:

<uses-permission android:name="android.permission.camera"/> <uses-feature android:name="android:hardware.camera" /> <uses-feature android:name="android.hardware.camera.front" android:required="false" /> <uses-feature android:name="android.hardware.camera.autofocus" />

is there way conditionally request access camera os's , not others? way achieve release 2 apps?

if app uses camera but it's not mandatory feature, can set required attribute false, did second feature.-

<uses-permission android:name="android.permission.camera"/> <uses-feature android:name="android:hardware.camera" android:required="false" /> <uses-feature android:name="android.hardware.camera.front" android:required="false" /> <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />

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.
