Developing with Phonegap Building mobile applications with HTML/JS Monday, January 23, 2012
Ryan Stewart Web Developer Evangelist, Adobe ryan@adobe.com blog.digitalbackcountry.com @ryanstewart github.com/ryanstewart Based in Seattle Things I Like: Beer Mountaineering/Hiking/Backpacking Geolocation/Mapping stuff Monday, January 23, 2012
Agenda • Why PhoneGap? • Who is PhoneGap...really? • Getting Started with PhoneGap • PhoneGap APIs • Extending PhoneGap • Final Considerations Monday, January 23, 2012
Why PhoneGap? Monday, January 23, 2012
The moral reason: The web is awesome Monday, January 23, 2012
The realistic reason Cross platform applications with HTML/JS will be faster and easier Monday, January 23, 2012
What is PhoneGap? Monday, January 23, 2012
Monday, January 23, 2012
Your Code Monday, January 23, 2012
Your Code Native Web View Monday, January 23, 2012
Your Code Native Web View Native APIs Monday, January 23, 2012
Your Code Native Web View Native APIs Native App - .apk, .ipa, etc Monday, January 23, 2012
PhoneGap uses the native browser on the device to render the HTML/CSS/JS Keep in mind that can affect the experience It also keeps apps nice and small Monday, January 23, 2012
PhoneGap uses the native project format for each platform. Open, emulate, and test from within the native development environment! Monday, January 23, 2012
Because it’s using the native projects it’s fully extendable. Monday, January 23, 2012
PhoneGap provides a JavaScript Library that reaches out into the native APIs. That means anything the device supports is doable. Monday, January 23, 2012
PhoneGap is completely open source and has been submitted to the Apache Foundation. Monday, January 23, 2012
It will be known as Cordova when it gets approved http:// incubator.apache. org/callback/ Monday, January 23, 2012
The entire project is available on Github https:// github.com/ cordova Monday, January 23, 2012
Getting Started Monday, January 23, 2012
There are multiple ways to “start” with PhoneGap. The project includes command line tools, IDE plugins, and Dreamweaver 5.5 ships with PhoneGap support. Monday, January 23, 2012
bin/create ~/Sites/phonegap_preso/demo Demo Monday, January 23, 2012
Quick tour through the project structure Monday, January 23, 2012
Demo: Hello World Monday, January 23, 2012
Quick segue: mobile web apps versus mobile applications Monday, January 23, 2012
Very important to keep in mind that we’re building a mobile app, not a mobile web app. Let’s look at jQuery Mobile Monday, January 23, 2012
You can use ANY framework you want, but try to design for an app. (I kind of like Bootstrap) Monday, January 23, 2012
Diving into the PhoneGap APIs Monday, January 23, 2012
- Accelerometer - Camera - Capture Out of the box, - Compass - Connection PhoneGap - Contacts provides support for a - - Device Events number of basic device - - File Geolocation APIs - Media - Network - Notification - Storage Monday, January 23, 2012
Camera API example Monday, January 23, 2012
Demo: Using the device APIs Monday, January 23, 2012
Debugging Monday, January 23, 2012
It’s all just HTML/JS, so you can use your browser! Take advantage of Chrome Developer tools/Firebug to test your app’s UI. Monday, January 23, 2012
But what about Device APIs? Because we’re in the web view, there is no way to do line-by-line debugging. Monday, January 23, 2012
Luckily we have Weinre, which lets us debug and manipulate the DOM from our PCs. Monday, January 23, 2012
Weinre can be configured as a server (there is a Mac application) and uses the developer tools from Chrome to provide hooks into the mobile app. Monday, January 23, 2012
Drop in a <script> tag on a remote server and Weinre will let you use the Developer Tools on your apps. Requires internet access, so keep that in mind. Monday, January 23, 2012
Demo: Debugging with Weinre Monday, January 23, 2012
But, a much easier way: http:// debug.phonegap.com/ Monday, January 23, 2012
Demo: debug.phonegap Monday, January 23, 2012
Extending Phonegap Monday, January 23, 2012
For added functionality PhoneGap provides a plug-in mechanism. Includes OS-specific code/libraries and the JS to use it in PhoneGap Some of the helpful ones: PayPal, Facebook, Push Notification Monday, January 23, 2012
Plug-is are one of the areas that show off the power of a hybrid web/ native approach. There are a ton of native-centric SDKs (like Facebook) that provide a great native experience. We can use those! Monday, January 23, 2012
Available at https://github.com/phonegap/phonegap-plugins Monday, January 23, 2012
This app can just use the plugins.barcodeScanner.scan method to call out to some native code that reads and parses a barcode. Monday, January 23, 2012
Demo: PhoneGap Plugins Monday, January 23, 2012
Final Considerations Monday, January 23, 2012
Remember that we’re on different platforms Monday, January 23, 2012
Versus http://developer.apple.com/library/IOs/#documentation/ UserExperience/Conceptual/MobileHIG/UIElementGuidelines/ http://developer.android.com/design/index.html UIElementGuidelines.html Monday, January 23, 2012
Some important performance implications: Currently only iOS hardware accelerates CSS3 transitions. Monday, January 23, 2012
Couple of tips: Always test features first (if !supported) For UI-specifics, you can use the device class to get device info Monday, January 23, 2012
Demo: PhoneGap in Action Monday, January 23, 2012
One more thing. build.phonegap.com Monday, January 23, 2012
The Problem: You’re building a cross-platform app, but dealing with a lot of native projects Monday, January 23, 2012
The Solution: Monday, January 23, 2012
Monday, January 23, 2012
Build includes git support so you can use git and host projects on PhoneGap or build a project from Github. Monday, January 23, 2012
Build lets you define individuals as tester/ developer which changes permissions on the project accordingly. Monday, January 23, 2012
You can use Build as your testing distribution as well by making the download pages public. Monday, January 23, 2012
Will (soon) support popular plugins so that you can build plugins right into the build process. Monday, January 23, 2012
Supports multiple PhoneGap versions so you can target a wide range of devices. Monday, January 23, 2012
Demo: PhoneGap Build Monday, January 23, 2012
