Hey guys try this and see if it works. It's not an app but better than nothing.
Step 1: Enable USB DebuggingOn your Android phone, go to Settings, Applications, and then Development. Check the checkbox for "USB debugging."
Step 2: Download the Android SDKDownload the SDK for your platform
here. Go ahead and plugin your Android handset into a USB port on your computer, if it is not plugged in already.
Step 3: Run DDMSYou need to open up the DDMS application from within the "tools" folder in the Android SDK's main folder.
After DDMS launches, select your handset from the menu on the left (it should be the only device listed). You might see an error message, but the debug tool should be loaded. Then, click CTRL-S on your keyboard. This will bring up the "Device Screen Capture" interface. From here, a static image is captured from what is appearing on your handset. You can save the image (nicely defaulted as PNG) and then refresh to your heart's content to grab updated or different screenshots from your phone.
Try this.
