As the Apple iPhone can take screenshots from just holding down the Power and Home buttons, while it would save a screenshot in the Camera Roll, the Android devices do not have this option in any version of this OS made for smartphones by Google. Though there is always an app for that!, and with a third party app you can just do, just that, buy using a component of the Android SDK.
To utilize this app, once you have the Android SDK configured, along with the USB drivers included, if you already have them installed that is good. If you don’t know how to install them check this guide out here.
First off you must have USB Debugging enabled which is done by going to Settings, Wireless and Network, USB Settings and you just click on which setting you want, which is USB Debugging mode of course.
By connecting your Android to your PC via uSB, go into the tools folder in the Android SDK and run the file “ddms”.
This brings up a Dalvik Debug Monitor Service, which allows you to see your device connected on the very top, and in the messages pane’s, this debugger could continue to give error messages, so just ignore them.
Under the menu of Device, click on Screen Capture or hold down Ctrl + S inside the Debugger window that you can see here:
Alast you can see the Device Screen Capture window as long as you are next to your PC or laptop. If you want you can rotate the photo, or copy it to your own clipboard. When going into the new screen on your device, simply click Refresh on the capture image thing and the photo will change. Click “Done” when you are complete.
This way of doing it is not the easiest way, though it’s the main way of doing, or the official way I should say. The photos are always saved to a folder in PNG format, so they aren’t too big at all, as it’s just a screenshot of a small phone screen too. Your memory card is unable to be accessed while in debug mode, remember. So screenshots of movies, or your music, etc is not even possible.
Those photos that are taken can be the interface of your Android device as long as you are connected through USB Debugging mode, while connected to your PC. Lame, I know. I know that eventually the feature of taking screenshots while on the go will be an option one day, Google just has some catching up to do with it’s firmware releases. On my Galaxy S, I’ve had two firmware updates so far in the past 8 months. Not bad at all, and they are all free, as they should be. The problem with firmware upgrades though is with Android devices, Google releases the firmware and the manufacturer of your phone has to modify the firmware update for it to work on their phone. I’ve got the best selling Android phone ever made, so it’s probably why I get updates so frequently.
