I have implemented a simple Android application that I now would like to test

  • 0

I have implemented a simple Android application that I now would like to test on a real device. I have a Nexus One.

In the Android Eclipse plugin, I have downloaded and installed the USB driver (revision 3) package. But when I connect my Nexus One to my PC (running Windows 7) using the USB cable, a message box pops up and shows that “No driver found” for “Nexus One”.

Driver Software Installation

I have activated USB Debugging on my device. And when I run adb devices on my PC, it just prints List of devices attached and no devices are listed. And if I use Device Manages in Windows, and tries to update the driver for “Nexus One”, I can not select a driver in the “driver directory” of Android SDK.

How can I install a driver for Nexus One on Windows 7 so I can use it for USB debugging my Android applications on a real device?

    The USB driver for Windows is a downloadable component for the Android SDK. If you are developing on Windows and would like to connect an Android-powered device to test your applications, then you will need to install the USB driver.

    This document provides information about the latest version of the USB driver and a guide to installing the driver on your development computer.

    USB Driver for Windows, Revision 3 (January 2010)
    Adds support for the Nexus One.

    The USB Driver for Windows is
    available for download as an optional
    SDK component. You need the driver
    only if you are developing on Windows
    and want to connect an Android-powered
    device to your development environment
    over USB.

    To install the driver or upgrade your
    existing driver to the latest
    revision, you must first download the
    driver to your development computer.

    To download the driver, use the
    Android SDK and AVD Manager tool that
    is included with the Android SDK. If
    you haven’t yet installed the Android
    SDK, as described in Installing the
    Android SDK    , please do so before
    continuing with the driver
    installation.

    When you are ready to download the
    driver, follow the instructions given
    in Adding SDK Components to launch the
    Android SDK and AVD Manager. From the
    Available Packages panel, select “Usb
    Driver Package” and download it to
    your computer. The driver files are
    downloaded into the <sdk>\usb_driver
    directory.

    After the download, follow the
    instructions below to install or
    upgrade the driver, based on your
    needs and Windows operating system
    version. If you are connecting an
    Android-powered device to your
    computer for the first time, follow
    the below procedure to “Perform a
    fresh installation.” If you have
    installed one of the older USB drivers
    and would like to upgrade to the
    latest version, follow the procedure
    to “Upgrade an existing driver.”

    Once you’ve completed the USB driver
    installation, please see Developing on
    a Device     for other important
    information about using an
    Android-powered device for
    development.
