Screen-caps, screen-grabs, screen-shots… Whatever you call them, the ability to take one is at the top of the list of reasons to root your Android device. Yes, there are alternatives to running a root-only app to attain screen-grabs, but none are quite as easy to set up and use.
There are many apps out their for saving screen images, but Drocap2 is all I need. The app is incredibly simple and effective. Here’s how it works:
When you first open Drocap2, you’re greeted with a little information about the app, including instructions.
“Tap start button and shake the device or wait for timer to capture screen image. You can also make a capture trigger from the Notification bar. If you recently execute drocap2 application, long pressing home key will will bring the diralog [sic] of recently used applications in any time.”
After that, you have two options – start the shake trigger or press the menu key for preferences.
Should you decide to use the shake trigger command before messing with any of the preferences, things are pretty straight forward. You just press “Start,” back out of Drocap2, shake your device, and an icon will show up in your notification bar letting you know your screen-cap is ready. By default, all screen-caps will go into a folder on your SD card titled “drocap.” They’ll have the prefix “cap,” and be saved as a JPEG. Just like most root only apps, all of these settings can be changed.
By pressing the menu key from the Shake Trigger screen, you can press Info (which brings up the original start dialog), or Preferences. From there, you can change several things.
Capture mode – This is perhaps the most important option within Drocap2. Changing the capture mode changes how you take your screen-cap. If you don’t like the Shake trigger (which I personally cannot stand), you can change the capture mode to Timer trigger, or Notification trigger. Timer trigger mode will enable a slider bar to appear when you open Drocap2, which you can slide to select how long it will take to go from start to picture. Notification trigger mode (my favorite) puts a small camera icon in your notification bar that you can press to take a screen-cap at anytime. This mode isn’t the best for taking screen-caps of games, or any other app that hides your notification bar, but for everything else it’s easily the most convenient.
Picture format – From the Picture format option, you can select to have your images saved as JPEG or PNG. For more information on that, I’d advise looking elsewhere.
Tick sound – Enable or disable sound.
Filename prefix – Every image you take can have a prefix added to it for. There’s several reason you may want to do this, for example screen-caps associated with a root only app review on Drocap2 would be easy to sort if every one started with something like “DC2.”
Folder name – This function is pretty self-explanatory.
Auto registration – The Auto registration option allows you to enable or disable notification registration on reboot. Essentially, change whether or not Drocap2 starts on reboot.
That’s all for this week, don’t forget, if you have any questions just use the comments or get ahold of me on Twitter: @du57in. As far as screen-cap apps go, Drocap2 is the only one I’ll need to whitelist.
