Fix Android device not showing up on Windows 8
I’ve been doing, or trying to do, some Android development on my new Windows 8 machine, but every time one problem gets fixed a new one seems to pop up.
Problem: Can’t debug using my Android tablet.
Step 1: Confirm computer can’t see device:
- Open a command window
- Navigate to <sdk-install>\sdk\platform-tools where you have adb.exe
- Enter ‘adb devices’
- If your computer can see your device you will see it’s serial number
Quick Fix: Switch the device into PTP mode (under Settings -> Storage -> USB Computer Connection.) and connect to computer. Let it install, switch back to USB mode and plug in again. This sometimes is enough.
Step 2: Enable USB debugging on your device:
On pre-Version 4.2 developer mode is just an option in settings.
On Version 4.2 or higher or higher you have to perform a weird/cool sequence to unlock usb debugging:
- Open up “Settings”->
- “About phone” or “About tablet”.
Scroll to the bottom and tap on “Build number” seven times.
- If done properly you will see a “You are now a developer!” message
- Don’t skip this > Now you can toggle USB debugging any time from: “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.
Step 3: Install USB driver (Windows auto install is not good enough)
- Download the USB driver with the SDK Manager: http://developer.android.com/sdk/win-usb.html
- Install it using Windows Device Manager: http://developer.android.com/tools/extras/oem-usb.html#InstallingDriver
Step 4: Repeat Step 1 to test if it’s now working.
Restart your computer and device, and try Step 1 again.
