Sensey

Android library which makes playing with sensor events & detecting gestures a breeze.

The library is built for simplicity and ease of use. It eliminates most boilerplate code for dealing with setting up sensor based event and gesture detection on Android.

Changelog

Starting with 1.0.1, Changes exist in the releases tab.

Including in your project

Sensey is available in the Jcenter, so getting it as simple as adding it as a dependency

implementation 'com.github.nisrulz:sensey:{latest version}'

where {latest version} corresponds to published version in

Simple example

• To initialize Sensey under your onCreate() in the activity/service, call

Sensey.getInstance().init(context);

• To stop Sensey, under your onDestroy() in the activity/service, call

 // *** IMPORTANT ***
 // Stop Sensey and release the context held by it
 Sensey.getInstance().stop();

• Next to enable shake detection

  • Create an instance of ShakeListener

  ShakeDetector.ShakeListener shakeListener=new ShakeDetector.ShakeListener() {
      @Override public void onShakeDetected() {
         // Shake detected, do something
     }
  
     @Override public void onShakeStopped() {
         // Shake stopped, do something
     }
  };

  • Now to start listening for Shake gesture, pass the instance shakeListener to startShakeDetection() function

  Sensey.getInstance().startShakeDetection(shakeListener);

  If you want to modify the threshold and time before declaring that shake gesture is stopped, use

  Sensey.getInstance().startShakeDetection(threshold,timeBeforeDeclaringShakeStopped,shakeListener);

  • To stop listening for Shake gesture, pass the instance shakeListener to stopShakeDetection() function

  Sensey.getInstance().stopShakeDetection(shakeListener);

Pull Requests

I welcome and encourage all pull requests. It usually will take me within 24-48 hours to respond to any issue or request. Here are some basic rules to follow to ensure timely addition of your request:

1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (Reformat code) on Mac (not sure for Windows) with Android Studio defaults. This project uses a modified version of Grandcentrix's code style, so please use the same when editing this project.
2. If its a feature, bugfix, or anything please only change code to what you specify.
3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge :)
4. Pull requests must be made against develop branch. Any other branch (unless specified by the maintainers) will get rejected.
5. Check for existing issues first, before filing an issue.
6. Have fun!
