Apache Cordova: Package/Build iOS/Andorid App from Polymer HTML5 Project

Requirement: Build iOS/Android app using existing Polymer project.

Solution:

There’re lots of tools/platforms to build an app from HTML5 project, such as Trigger.io, Intel XDK, PhoneGap, Apache Cordova. I choosed Cordova to build my first html app;

Install Apache Cordova by npm:
```
$ sudo npm install -g cordova
```

Create a Cordova project using cordova CLI;

$ cordova create hello com.liguoliang.app HelloWorld

Navigate to the project folder, add platform:
```
$ cordova platform add ios/android
```
Build project:
```
$ cordova build
```
Emulate the app:
```
$ cordova emulate ios/andorid
```

Note: It is required to install Xcode or Android SDK/Tools for simulating. you may follow the Cordova CLI message to installed the required sdk/tool.
