Getting Started with Android

If this is your first Phidget, we highly recommend working through the Getting Started guide for your specific Phidget device, which may be found in its user guide.


The Phidget libraries for Android development are available here:

Download and unpack the libraries. You will need to reference these files from your project in order to use Phidgets. This step is covered in detail in the Android Java page.

Direct USB Connection

For directly controlling a Phidget with your Android device (i.e. plugging a Phidget directly into your device), you will need to ensure the device is capable of being a USB host. Just having a port that the USB cable can fit into does not necessarily indicate that the port can host a USB device. On the other hand, some phones can use an OTG (on-the-go) cable to allow plugging USB devices into their charging port. Some tablets (like the Samsung Galaxy Tab, for example) have the large 30-pin connectors that can be changed into a USB host using an adapter.

The best way to know before getting your hands on a device is to check its specifications for whether it can serve as a USB host. Alternately, a quick way to figure out if your device can serve as a USB host is to try plugging other devices (such as a mouse, or USB memory stick) into your Android device.

Network Server

In applications where you aren't plugging Phidgets into your Android device directly, you must have a host computer that is running the Phidget Network Server.

  • Host computer: the computer that is physically connected to the Phidgets via USB and is running the Phidget Network Server.
  • Client computer: a computer running a Phidgets application that accesses Phidgets connected to the host computer. When developing for Android, your Android device acts as the client.

In this case, you will need to install the Phidget libraries on your host computer, and get the Phidget Network Server up and running. Follow the Getting started guide, and continue with the Network Server guide for your operating system. When you are done, come back and finish this guide!

Programming Languages

Now that you have the basics set up, check out the Android Java page for information on how to write code for Phidgets to run on your Android device.

Note that Android Java is NOT the same as mainstream Java. Any Java programs you have will probably need significant modification before they run on Android, including our mainstream Java Phidget Examples.
