fragment tab paging

Download: http://www.mediafire.com/?puv6e3ls6vcqe0v

apk fie install from termina

$ echo $PATH ---(should return the directories associated with $PATH)

$ export PATH=$PATH:/home/YOUR-USERNAME/sdk/tools
---(replace with path to your tools directory, you may need to add 'sudo' to the beginning of this cmd)
Update: later versions of the SDK have ADB moved to the platform-tools directory, so adjust the above accordingly.

$ echo $PATH
---(you should now see your tools directory added to the end of the $PATH variable)

$ adb devices
---(now adb should do something, if nothing else at least error, no devices)

And now I get:


List of devices attached
emulator-5554 device

uninstall cmd: adb uninstall com.stylingandroid.viewpager

install cmd: adb install ~/Downloads/BarcodeScanner3.6.apk
