PhoneGap/Android

PhoneGap/Android is an Android application library that allows for PhoneGap based projects to be built for the Android Platform. PhoneGap based applications are, at the core, an application written with web technology: HTML, CSS and JavaScript.

Pre Requisites

• Java JDK 1.5
• Android SDK http://developer.android.com
• Apache ANT
• Ruby (Optional, see section: DroidGap with JRuby)

Install

On any POSIX machine add PhoneGap/Android to your PATH variable like so:

export PATH=$PATH:~/phonegap-android/bin

On Windows add the phonegap-android/bin to your PATH as normal.

DroidGap: PhoneGap/Android Dev Script

Tools for developers building mobile apps using PhoneGap for Android.

Usage:

droidgap [command] [parameters]

Commands:

	help ...... See this message. Type help [command name] to see specific help topics.
	gen ....... Generate an example PhoneGap application to current directory.
	create .... Creates an Android compatible project from a WWW folder. 
	classic ... Backwards support for droidgap script. Run "droidgap help classic" for more info.
	update .... Copy a fresh phonegap.jar and phonegap.js into a valid PhoneGap/Android project.
	test ...... Gets edge copy of mobile-spec and runs in first device or emulator attached.

Quickstart:

  	$ droidgap gen example 
  	$ cd example
	$ ant debug install && adb logcat

DroidGap with JRuby

If you want to use the droidgap command but do not want to install Ruby then you can call it using jruby jar included in the lib folder. All the options are the same and a call looks like this:

java -jar jruby-complete-1.4.0RC1.jar ../bin/droidgap help run

Keep in mind this will be slower due to JVM warmup.

Importing a PhoneGap/Android app into Eclipse

1. File > New > Project...
2. Android > Android Project
3. Create project from existing source (point to the generated app found in tmp/android)
4. Right click on libs/phonegap.jar and add to build path
5. Right click on the project root: Run as > Run Configurations
6. Click on the Target tab and select Manual (this way you can choose the emulator or device to build to)
