added ability to get gyro input (DiDirty skill uses it)

add <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
to the manifest.xml file above <application

add interface (kotlin):

Code:

interface AccelerometerListener {

    fun onAccelerationChanged(x: Float, y: Float, z: Float)

    fun onShake(force: Float)
}


add a class named AccelerometerManager.kt (kotlin)

main activity.kt :

added JikanMon.kt time gate.

this class stabilizes the gyro input, so it filters out an input overload by violent shakes. only up to 1 input per x seconds

Code:

package com.yotamarker.lgkotlin1

class JikanMon {
    private val playGround = PlayGround()
    private var x = -1
    private var timePause = 3
    val isBlocked:Boolean
        get() {
            val nowSeconds = playGround.getSecondsAsInt()
            if ((x < 0 || nowSeconds > x) || (x > 60 && nowSeconds > (x - 60)))
            {
                x = -1
                return false
            }
            return true
        }
    fun block() {
        this.x = playGround.getSecondsAsInt() + timePause
    }
    fun setTimePause(timePause:Int) {
        if ((timePause > 0) && (timePause < 30))
        {
            this.timePause = timePause
        }
    }
}

the functions handling movement input :
onShake(force:Float)
*onAccelerationChanged which has room for alg improvements ATM (the inside of the function)
