What is QuickCamera?

QuickCamera is a free and open source application that lets you quickly launch the camera app (normally or from the lock screen) with a simple gesture that involves twisting your wrist twice, quickly. It's the same gesture that's used to launch the camera app on the Moto X. Pull out your phone, perform the gesture and the camera app will be ready to take wonderful photos. No need to wake the phone or press any buttons.

Why did I make this?

I am a big fan of Moto X's gesture controls and I really liked the gesture to launch the camera from anywhere, by twisting your wrist quickly 2 times. It's really handy, but unfortunately not available to other devices, so I decided to replicate the feature and bring it to all Android devices. It involved weeks of experimentation, but I finally have a working alpha version ready.

Changelog:

Alpha 10 - May 2nd 2014


  • Night mode: Automatically disable gesture recognition when you go to sleep and automatically enable it when you wake up. To set the wake-up and sleep time, enable Night Mode in Settings and set the wake-up and sleep timings. This saves battery life substantially.
    Inbuilt QuickCapture camera app: Not available for testing right now but will be soon
    Optimizations to code and some bug fixes
    Improvements to Gesture Calibration: Added a help button

Alpha 9 - April 30th 2014

  • Option to enable/disable gesture recognition only when the screen is off
  • Ability to save calibration settings without trying them
  • Fixed bugs in Settings

Alpha 8 - April 30th 2014

  • Improvements to accuracy and sensitivity; completely switched to rotation vector now
  • Gesture Calibration option added: You can now adjust the sensitivity/accuracy values and try them out to see which combination works the best for you. Once you're satisfied, you can save the values and the service will start using them
  • Added an option to let you control whether the service should automatically start after rebooting or not

Older alpha version changelogs

Alpha 7 - April 30th 2014

  • Switched to rotation vector by default, accuracy and sensitivity highly improved and chances of accidental launches significantly reduced
  • Added an option to change vibration intensity in Settings
  • Bugfix: Camera launch due to vibration on notifications like messages, etc

Alpha 6 - April 29th 2014

  • Improved sensitivity: Gesture will now activate ONLY if you twist your wrist 2 times within 2 seconds, else the gesture will not be recognized. It should fix most of the accidental launch issues everyone was having!
  • Slightly improved battery usage
  • Gesture detection now pauses when when a call comes and resumes when the call ends

Alpha 5 - April 28th 2014

  • Lockscreen and screen off support (Requires Google Camera on some devices)
  • Bugfix: Performing gesture on lockscreen disables security

Alpha 4 - April 28th 2014

  • Reduced battery consumption when the phone is in your pocket (Make sure you enable proximity sensor in Settings)
  • Improved accuracy/sensitivity
  • Bugfix: Camera launched in pocket even when proximity sensor was turned on in Settings
  • Bugfix: Pressing the back button did not put the application in background
  • Bugfix: If camera app was already in background and gesture was performed, the camera app will open but throw an error.
  • Prevent accidental camera launch while the user is in a call

Alpha 3 - April 27th 2014

  • Vibration on camera launch
  • Service auto-starts on device startup
  • Tutorial when you launch the app for the first time
  • Settings menu now exposed (No need to press volume down button 3 times!)

Alpha 2 - April 27th 2014

Alpha 2 has been pushed, will go live in few hours and you will receive an update via Play Store. I have attached the APK in OP also. Oh, and I forgot to mention: You can access the debugging settings by pressing volume down button 3 times in the app.

Wow... Great stuff.. I mean.. Really great!!! Neo V running 4.4 works flawlessly.. Only one thing. I cant seem to find any settings. I'd like to change the time between the twists because IMO its too long.. (Even after 5-6 seconds it would activate.)

Open the app, press volume down button 3 times, the debug settings will open. You cannot change the time between twists, but you can tweak one value which affects the twists in a certain way (X-axis threshold).

Works on the note 3 but it seems to have trouble bypassing the lock screen and seems too sensitive. I assume changing the axis threshold would help with that?

Thank you for this app.

I could not get it to work on my rooted Note 2 running Kitkat 4.4.2 (IOAP ROM) w/AGNI kernel

I tried to change axis threshold values between 0 to 10 and none worked.

Also, how do you exit the app after turning it on ? I have to use the home button to get out.

Please send logcat, without it I cannot identify what went wrong on your device. Also, are you performing the gesture properly?
You can close it from multitasking menu.

    linear accelerometer and value 3 worked for me.
    on 4.4.2 stock btw.

    steps :
    open app.
    go to debug menu via volume down button pressing 3 times.
    select linear and make value you like. i did 3.
    go back to main screen.
    activate.
    press home button.
    lock screen and do gesture like shown in 1st page.

      Hey folks, just wanted to make a small announcement. The feedback I am getting on this app is phenomenal and I've been working hard every single day to fix the bugs and improve the app even more. It's almost been a week since I launched this app and so far I have added many new features and improved the accuracy tremendously. This app is now ready to enter BETA testing stage & I will be releasing the first BETA build in a few days. Current ALPHA testers will automatically start receiving beta builds, so you don't have to worry about anything.

      What can you expect from the beta builds? Since the accuracy of the gesture recognition has been significantly improved, beta builds will focus on new features (like an inbuilt QuickCapture camera app) and battery saving. Yes, I will still be improving accuracy even more and fixing bugs, but the main focus will be on the above two things. If there's anything you'd like to see (like a new feature) in the beta builds, then you can comment below.

      Also, the first beta build will bring back something that a lot of people have been asking for ;)

      Awesome, it is! :good: :good: :good:
      Well, you have given the source, but I,m still asking, can i implement it in my ROM as an inbuilt feature?

      You can do anything you like, as long as you follow the license (GPL v2)

      Publishing Alpha 10 to the Play Store, it will be live in a couple of hours!
