This easy tutorial describes how to make an Android application with PhoneGap & jQuery Mobile to send streams to Altair SmartWorks. In this project you will learn how to:
- Set up your development environment
- Make an easy Android application with PhoneGap & jQuery Mobile
- Send streams to Altair SmartWorks with your Android application
- Your favorite IDE, in our case Eclipse
- Android SDK
- ADT Plugin
- The latest copy of PhoneGap (in our case cordova-2.9.0)
- The latest copy of JQuery Mobile (in our case JQueryMobile 1.3.2)
- An Android phone

This project is a quick way to create an Android application and understand how to send streams to Altair SmartWorks using PhoneGap and jQuery Mobile.
Here is overall diagram of the project:
All the data streams sent by the phone are collected and stored in Altair SmartWorks. Altair SmartWorks is a huge database that collects all the information that your sensors send.
In addition to storing data, the true power of Altair SmartWorks is to let you build Apps very quickly with few lines of Groovy code.
With Altair SmartWorks you can build very complex Apps to support all the logic of your product on the cloud and integrate it with other devices and IT systems. But for now let’s keep it simple.
If you are a new Android developer, the best way to start is download the ADT Bundle.
ADT Bundle includes everythings you need to begin developing apps:
- Eclipse + ADT plugin
- Android SDK Tools
- Android Platform-tools
- The latest Android platform
- The latest Android system image for the emulator
Setting Up the ADT Bundle
- Download ADT Bundle
- Unpack the ZIP file and save it to an appropiate location
- Open the adt-bundle-your_platform/eclipse/ directory and launch eclipse
- That's all!. Your IDE is already loaded with the Android Developer Tools plugin and the SDK ready to run
This point describes how to set up your development environment for PhoneGap.
Select menu item -> New project -> Android Application Project
- New Project
Complete the remaining windows with the desired values for your project.
In the project root directory, create this directories:
Copy PhoneGap libraries
- Download PhoneGap Files (in our case 2.9.0 version)
- Copy lib/android/cordova.js to /assets/www
- Copy lib/android/cordova-2.9.0.jar to /libs
- Copy lib/android/xml folder to /res
- Add cordova-2.9.0.jar in the project Build Path.
Right click on the libs folder, go to Build Path -> Configure Build Path -> Libraries Tab and add cordova-2.9.0.jar to the project
- Refresh the project (F5)
Edit the main activity java file in src folder
- Add import org.apache.cordova.*;
- Change the visibility from private class MainActivity to public class MainActivity
- Change the class's extend from Activity to DroidGap
- Replace setContentView()line by super.loadUrl("file:///android_asset/www/demo1.html");
Configure the file AndroidManifest.xml
- Type the following permissions between uses-sdk and application tags
- Type on tag activity the following configuration:
Check that everything is correct
- Create a new file named demo1.html in /assets/www with the following code:
- Run in the simulator.
Right click on the project and Run As -> Android Application
- Run in your device.
Make sure USB debugging is enabled on your device and plug it into your system. Right click on the project and Run As -> Android Application
To create a complete look and feel for our app, we need JQuery mobile.
- Create a css folder under assets/www. This will be the place for your applications css files
- Create a vendor folder under assets/www
- Create a jquery.mobile folder under assets/www/css. This will be the place for your JQuery Mobile css files
- Download JQuery File (in our case 2.0.3 version)
- Download JQueryMobile Zip File (in our case 1.3.2 version)
- Copy .css files and the images folder from your JQueryMobile zip file to assets/www/css/jquery.mobile folder
- css files
- Copy .js files to assets/www/vendor
- js files
- Add in the head tag to demo1.html file a meta tag to provide information which will be used by JQuery Mobile to improve the device rendering
- Add the JQuery Mobile stylesheets to demo1.html file
- Add JQuery and JQuery Mobile .js files to demo1.html file
- Modified demo1.html file with the following code to check that JQuery Mobile is working
- The code will be like this:
- Final code
- And the result:
If youre registered in Altair SmartWorks, you have a default device already created for you.
Check your control panel and see what it looks like.
Basically you need the device id_developer that might be something like defaultDevice@myusername.
But if you want, you can create a new device and use it in this example.
Now, go to your control panel “My account menu” and check your Apikey.
Its a big alphanumeric token like:
You need this number to complete the example.
From ypur phone you have to build a HTTP request and send the data.
POST /streams HTTP/1.1
Apikey: YOUR APIKEY HERE
"device":"YOUR DEVICEs ID_DEVELOPER HERE",
It's time to build our interface and send a stream to Altair SmartWorks
- Edit the file demo1.html body tag and replace with the following code:
- Add application.js file to demo1.html head tag
- The code will be something like this:
- In application.js file, type the code to send a stream to Altair SmartWorks
- Run in simulator or device (where you prefer), and push button to send a stream to Altair SmartWorks
- Android App (JQuery Mobile + PhoneGap)
If you get here, your device must be sending streams when you turn on and turn off the lights.
Its time to test our control panel and check if we have new streams.
Go to “Data management” → “Data streams” and you will see your data.
- menu option
Now you know how to create a simple App for your Android phone and send streams to Altair SmartWorks. But you can enhance this project in many ways.
In a second part of this tutorial, you will learn how to send to Altair SmartWorks your custom data.
