set android development environment

before can build android applications, must install android sdk. installing android sdk installs avd manager, graphical user interface creating , managing android virtual devices (avds).

from android web site, download correct version of android sdk operating system.

unzip archive location of choosing. example, on linux or mac, can place in root of user directory. see android developers web site additional installation details.

configure android_home environment variable based on location of android sdk. additionally, consider adding android_home/tools, , android_home/platform-tools path.

windows set android_home=c:\\android-sdk-windows set path=%path%;%android_home%\tools;%android_home%\platform-tools

to run code in guide, need download , install latest sdk platform. using android sdk , avd manager installed in previous section.

  1. open android sdk manager window

  2. select tools checkbox.

  3. select checkbox latest android sdk.

  4. from extras folder, select checkbox android support library.

  5. click install packages…​ button complete download , installation.

if not have android device testing, can use android virtual device.to this, must first install android sdk , install corresponding sdk platforms , packages. see set android development environment.

this command creates new avd named "default" based on android 5.1, api level 22:

android create avd --name default --target android-22 --abi armeabi-v7a

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.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
