This is useful tip for Android developers on Windows, especially if you are AIR for Android developer and use Flash Builder or Flash Professional and want to debug and test your apps on mobile phone via USB. On Mac I didn’t have any problem, I just plugged device via USB and it has started working. On Windows it’s a little more tricky. It’s missing driver problem.
First, you install Android SDK.
And when you connect your Android device via USB – it can happen that you see empty list of devices by calling: adb devices command available in android-sdk/tools folder.
Alright, the problem is that you don’t have your Android USB device driver installed and default Windows driver isn’t enough.
You can find the driver in android-sdk/usb-driver folder.
You see, that Nexus One shows some warning. Open it, reinstall driver by pointing to android-sdk/usb-driver folder.
