detect Shake in android

Question

I am trying to hit an API when user shake a device 10 times. I have tried many git sample and stack overflow solution but non of them did solve my problem. Some of them detecting shake before 10 times or after 10 times. I have tried Seiamic and ShakeDetector libraries. Please give me some valuable solution.

Answer 1

I have done that using this library :

1) Add the dependecy in your build.gridle file

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

dependencies {
   compile 'com.github.safetysystemtechnology:android-shake-detector:v1.2'
}

2) Give the permission to your app manifest file

<uses-feature android:name="android.hardware.sensor.accelerometer" android:required="true" />

if you will run in background, register your broadcast receiver

<receiver android:name=".ShakeReceiver">
    <intent-filter>
        <action android:name="shake.detector" />
    </intent-filter>
</receiver>

3) start that in onCreate method Like this :

private ShakeDetector shakeDetector;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    buildView();

    ShakeOptions options = new ShakeOptions()
            .background(true)
            .interval(1000)
            .shakeCount(2)
            .sensibility(2.0f);

    this.shakeDetector = new ShakeDetector(options).start(this, new ShakeCallback() {
        @Override
        public void onShake() {
            Log.d("event", "onShake");
        }
    });

    //IF YOU WANT JUST IN BACKGROUND
    //this.shakeDetector = new ShakeDetector(options).start(this);
}

4) override onStop method and stop that

@Override
protected void onStop() {
    super.onStop();
shakeDetector.stopShakeDetector(getBaseContext());
}

5) override onDistroy method and distroy like this :

@Override
protected void onDestroy() {
    shakeDetector.destroy(getBaseContext());
    super.onDestroy();
}

(*) Optional step : if you will run in background, create your broadcast receiver

public class ShakeReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (null != intent && intent.getAction().equals("shake.detector")) {
            ...
        }
    }
}

Answer 2

By Using SensorListener

Please check this ticked answer...

You have to adjust SHAKE_THRESHOLD value to achieve this

Thank you!

Answer 3

have a static variable that gets incremented every time a shake is detected.

static int count = 0;
public void onSensorChanged(SensorEvent event) {
if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
    long curTime = System.currentTimeMillis();
    if ((curTime - mLastShakeTime) > MIN_TIME_BETWEEN_SHAKES_MILLISECS) {

        float x = event.values[0];
        float y = event.values[1];
        float z = event.values[2];

        double acceleration = Math.sqrt(Math.pow(x, 2) +
                Math.pow(y, 2) +
                Math.pow(z, 2)) - SensorManager.GRAVITY_EARTH;

        if (acceleration > SHAKE_THRESHOLD) {
            mLastShakeTime = curTime;
            count++;
            if(count==10){
                //your code goes here
            }
        }
    }
}
