Android is a mobile OS commonly used on smartphones and tablet computers.
Recommended Languages
Android OS programs are written in Java using the Android SDK and the Phidgets library.
Installing Libraries and Drivers
Development for your Android OS Phidget application can occur on Linux, Mac OSX, or Windows.
Setup
You will need the following:
- The JDK and Java on your development system
- The Android SDK package for your development system
- See the download link at http://developer.android.com/sdk/installing.html
- For 64-bit Linux, you will need the
ia32-libs
package as well
- The Eclipse plug-in for Java development
- http://www.eclipse.org/downloads/ for Windows or MacOS
sudo apt-get install eclipse
(for Linux)
- The Phidget Libraries for Android
- For using Android to control a Phidget remotely, the Phidget Webservice should be installed on the remote computer
- Click on the remote computer's OS on the List of Languages page for setup information
Step One: Install the Android SDK
Google's instructions for installing the Android SDK may be found here:
http://developer.android.com/sdk/installing.html
That link contains help and code for:
- Installing the SDK and platform emulators
- Connecting the SDK into Eclipse, which is useful for following the example descriptions later
Step Two: Run Google's Hello Android Application
To check that the JDK, the Android SDK, and Eclipse have all been configured correctly, use the Google HelloAndroid example:
http://developer.android.com/resources/tutorials/hello-world.html
Step Three: Install the Phidget Library
When you download and unzip the Phidget Library for Android, it will contain three things:
- A libs/ folder
- A jar file containing the general Phidget java library (phidget21.jar)
- A jar file for directly driving USB devices from a USB port on the Android device (PhidgetsUSB.jar)
To install libraries to run a Phidget remotely:
- Add libs/ and phidget21.jar to your project
- Add the following to your
AndroidManifest.xml
file:
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
To install libraries to run a Phidget directly (Android 3.1 and later, with USB port on device):
- Add libs/, phidget21.jar, and PhidgetsUSB.jar to your project
- Add the following to your
AndroidManifest.xml
file:
<uses-feature android:name="android.hardware.usb.host" />
In Eclipse, jar files and library files can be added by: Project → Properties → Java Build Path → Libraries (tab) → Add JAR
Common Problems and Solutions
If you are having trouble, ensure your Phidget libraries are up to date.
- List relevant problems from "Common Problems and workarounds" doc
- List common problems for this OS from support forums
Limitations
Android 3.1 and later can run Phidgets directly plugged into a local USB port.
Other versions of Android can remotely control Phidgets via the Phidget Webservice. This has been tested down to Android version 2.1.
