How to compile C++ Game for Andorid NDK using Mac Terminal and Ant

This is a walkthrough of building C++ application with Android ndk and ant without using Eclipse IDE

1. Download the latest Android SDK from http://dl.google.com/android/android-sdk_r23.0.2-macosx.zip

and install Java SDK SE from Oracle say jdk-7u71-macosx-x64.dmg
2. Download Android NDK from say https://dl.google.com/android/ndk/android-ndk-r9d-darwin-x86_64.tar.bz2

3. Install apache ant

Please take note that for Mac OSX Mavericks, ant is no longer in Mac, just download a binary distribution of Ant from http://ant.apache.org/bindownload.cgi . and unzip/untar it, and add its bin directory to PATH.

4. Use Mac Terminal and add path to the above three installation folders
e.g. export PATH=${PATH}:~/android-sdk-macosx/tools:~/android-sdk-macosx/platform-tools:~/android-ndk-r9d:~/apache-ant-1.9.4/bin


5. Use Terminal command android sdk and android avd to update the sdk (install sdk of minimum of API-15 (Android 4.0.x) and create a new avd)

If you use Intel HAX for fast virt mode in emulator, please set Use Host GPU to on.

6. Download some C++ game source code e.g. here http://www.apress.com/9781430258308 . Just download the Source Code from the book website and extract say chapter2.zip
If you want to support multiple platforms add this APP_ABI in HelloDroid/jni/Application.mk
APP_PLATFORM := android-16
APP_ABI := armeabi armeabi-v7a x86

7. ndk-build
cd ~/Download/HelloDroid
ndk-build clean && ndk-build

list target (assume sdk installed already in step 5 above)
android list target

update project with target 1 (assume target id 1 is already created with API-16 in step 5 above)
android update project -n com.beginndkgamecode.hellodroid -t 1 -p .

list avd (assume "NokiaX" is created in step 5 above)
android list avd

8. start emulator
emulator -avd NokiaX -scale 0.5 &

debug build
ant clean && ant debug

install apk to emulator
ant debug install

Note:
(1) use ant uninstall if need to remove
(2) use Control-fn-F12 to rotate the emulator in Mac
(3) the generated apk file is bin/com.beginndkgamecode.hellodroid-debug.apk
(4) add android:icon to AndroidManifest.xml like this to add a default icon.
<application android:icon="@drawable/ic_launcher" android:label="@string/app_name" ...

How to run Android 5.0 samples in Android Studio

(1) Install Android 5.0 and Android SDK Build-tools to 21.0.1 using the latest Android Studio


(2) Download the samples from github
say from https://github.com/googlesamples/android-RecyclerView
and use Import Project in Android Studio


(3) Install HAXM if you run emulator in Windows
After you download it make sure you run the setup located in:
{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe

If you get the error "VT not supported" during the installation disable Hyper-V on windows features. You can execute this command as administrator dism.exe /Online /Disable-Feature:Microsoft-Hyper-V. You will also need "Virtualization Technology" to be enabled on your BIOS.


If you are using Mac OSX 10.10 Yosemite, run this (to allow ALL UNSIGNED KEXT to be loaded)
sudo nvram boot-args="kext-dev-mode=1"
and reboot before installing the package in
{SDK_FOLDER}/extras/intel/Hardware_Accelerated_Execution_Manager/IntelHAXM_1.1.0_for_10.10.dmg


(4) setup AVD like below
Choose Intel Atom X86 and with Ram 768M (for Windows). You can use 2G for Mac


(5)change build.gradle file compileSdkVersion to 21 and buildToolsVersion to "21.0.1"
and also change AndroidManifest.xml file android:minSdkVersion= to "13"

CSS Selector in Chrome (Part 2) Apple On-line Store for iPhone 6

Apple On-line Store for iPhone 6 URL for HK is here
http://store.apple.com/hk/buy-iphone/iphone6

The selection flow and the CSS Selector code are listed as below


(1) Choose a model:

AOS/availability    Select all

<div id="group-1"> <div id="Item1" class="step"> <div class="selection"> <div class="small-size-buttons enabled"> <fieldset> <legend class="size-selection-header"> <h2 class="fwl"><span class="section-number step1"><span class="a11y">1</span>>/span> <span class="section-heading">Choose a model:</span> </h2> </legend> <div class="selection-buttons"> <div class="item "> <input type="radio" value="4_7inch" id="Item14_7inch" name="dimensionScreensize" class="a11y"> <label for="Item14_7inch"> <div class="details"> <div class="label"> <div class="size-label">iPhone 6 <span>4.7-inch display</span> </div> <div class="price"> <span itemtype="http://schema.org/Offer" itemprop="offers" itemscope="itemscope"> <meta itemprop="priceCurrency" content="HKD"> <span itemprop="price">From <span>HK$5,588</span></span> </span> </div> </div> </div> </label> </div> <div class="item "> <input type="radio" value="5_5inch" id="Item15_5inch" name="dimensionScreensize" class="a11y" checked=""> <label for="Item15_5inch"> <div class="details"> <div class="label"> <div class="size-label">iPhone 6 Plus <span>5.5-inch display</span> </div> <div class="price"> <span itemtype="http://schema.org/Offer" itemprop="offers" itemscope="itemscope"> <meta itemprop="priceCurrency" content="HKD"> <span itemprop="price">From <span>HK$6,388</span></span> </span> </div> </div> </div> </label> </div> </div> </fieldset> </div> </div> </div>

$("group-1 #Item1 div.selection-buttons div.item").eq(0).find("input").click();
where 0=iPhone 6; 1=iPhone 6 Plus


(2) Choose color:
$("group-1 #Item2 div.selection-buttons div.item").eq(0).find("input").click();
where 0=Silver; 1=Gold; 2=Space-Grey


(3) Choose storage:
$("group-1 #Item3 div.selection-buttons div.item").eq(0).find("input").click();
where 0=16GB; 1=64GB; 2=128GB


(4) Product Summary and Availability:
$("primary .product-title").text() + " " + $("actiontray .customer_commit_display").text();


(5) Enable Select button:

AOS/availability    Select all

<div id="actiontray" class="actiontray"> <ul class="purchase-info"> <li class="specials"></li> <li class="shipping"> Available to ship<b>:</b><br> <span class="customer_commit_display">Currently unavailable</span> <span class="freeshipping promo-text">Free Shipping</span> </li> <li> <span class="price"> <span class="current_price"> <span itemscope="itemscope" itemprop="offers" itemtype="http://schema.org/Offer"> <meta itemprop="priceCurrency" content="HKD"> <span itemprop="price"> HK$7,188 </span> </span> </span> </span> <span class="financing"></span> </li> <li class="add-to-cart"> <button class="button disabled" type="button" disabled="disabled"><span>Select</span></button> </li> <li class="shipping-lead"></li> </ul> </div>

Monitoring program see http://youtu.be/Nj1vcbEyhf4

CSS selector in Chrome using the example of Apple iPhone 6 Availability Monitoring

The iPhone 6 Reserve Page for HK is a dynamic web content as in
https://reserve.cdn-apple.com/HK/en_HK/reserve/iPhone/availability


An example of the implementation of monitoring program uses javascript and the Chrome browser and further automation to reserve an iPhone can possibly be completed using Webdriver JS from the Selenium + chrome driver (see http://youtu.be/I1-m_qcmQLk).

To start with and illustrate, the steps for the javascript code preparation are as below:

(1) Goto the website and open the javascript console (Control-Shift-J in PC, Cmd-Option-J in Mac) in Chrome browser



(2) Click the element tab, the dynamic webpage code can be revealed.

iPhone/availability    Select all

<div id="wrapper" class="check-availability"> <div class="two-col-container"> <div class="options-container"> <div class="availability-title-container"> ... </div> <div class="storeselect select-style products" style="..."> <select name="products"> <option value="">Select a model</option> <option data-index="0">iPhone 6 Plus</option> <option data-index="1">iPhone 6</option> </select> </div> <div class="storeselect select-style stores" style="..."> <select name="stores"> <option value="">Select a store</option> <option value="R409">Causeway Bay</option> <option value="R485">Festival Walk</option> <option value="R428">ifc mall</option> </select> </div>

(3) Use the CSS style locator (to be entered into the javascript console of Chrome Browser) as below to quickly locate the model selection box and make changes to it, eq(1) being iPhone 6 plus and eq(2) is iPhone 6.
div#wrapper means the div id locator for the id wrapper.
div.two-col-container means the div class locator for the class two-col-container.
$('div#wrapper div.two-col-container div.options-container select[name="products"] option').eq(1).select().attr("selected","selected").change();
$('div#wrapper div.two-col-container div.options-container select[name="products"] option').eq(2).select().attr("selected","selected").change();

(4) Similarly, the code to select the store is
$('div#wrapper div.two-col-container div.options-container select[name="stores"] option').eq(1).select().attr("selected","selected").change();

(5) To retrieve the dynamic content of the store info, use
$("div#wrapper div.two-col-container div.dropdown-container div.results-container .store").text() + $("div#wrapper div.two-col-container div.dropdown-container div.results-container .date").text();

(6) To retrieve the dynamic content of availability of say 16GB sliver, use
" 16GB " +$("div#wrapper div.two-col-container div.dropdown-container div.results-container .device-sizes tbody tr").eq(0).attr("class") + " " + $("div#wrapper div.two-col-container div.dropdown-container div.results-container .device-sizes tbody tr").eq(0).find(".16GB .isAvailableText").text();

(6.1) Similarly, 16GB gold is
" 16GB " +$("div#wrapper div.two-col-container div.dropdown-container div.results-container .device-sizes tbody tr").eq(1).attr("class") + " " + $("div#wrapper div.two-col-container div.dropdown-container div.results-container .device-sizes tbody tr").eq(1).find(".16GB .isAvailableText").text();

(6.2) For others, just repeat and substitute '16GB' for '64GB' and '128GB' and change the eq(0) to eq(1) and eq(2) for different colors, 0=silver, 1=gold, 2=space-grey.

(7) To click the Get Started button on the right of the webpage, use
$('div.skip-wrapper div.button-container .button')[0].click();



To automate the scripts, one possible solution is to use node.js + chromedriver
Download and Put the ChromeDriver (note that it is 32 bit only for Windows/Mac) on your PATH
http://chromedriver.storage.googleapis.com/index.html?path=2.10/

and then install node.js from
http://nodejs.org/download/
and see the WebDriver wiki here https://code.google.com/p/selenium/wiki/WebDriverJs

Note: for windows 8, please create folder in "%HOMEPATH%\AppData\Roaming\npm"
before installing WebDriver using "npm install selenium-webdriver"

appleiphone6_availability.js    Select all
