OOM allocating Bitmap with dimensions 16776943 x 63

[hereisderek]

my current implementation is

class EditSubPanelDrawView @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null) : LinearLayout(context, attrs) {

    @IntRange(from = 0x0, to = 0xFF)
    private var alphaValue : Int = 0

    @ColorInt
    private var colorValue : Int = getRandomRainbowColor(context)

    private val mComponentLayoutParams = LinearLayout.LayoutParams(dpToPx(200f).toInt(), dpToPx(30f).toInt()).apply{
        weight = 1f
        gravity = Gravity.CENTER
    }
    private val mColorPickerView : ColorPickerView by lazy {
        ColorPickerView(context).apply {
            layoutParams = mComponentLayoutParams
            setEnabledAlpha(true)
            setEnabledBrightness(true)
            setInitialColor(colorValue)
            subscribe { color, fromUser, shouldPropagate ->
                Timber.d("ColorPickerView newColor: $color")
                colorValue = color
            }
        }
    }
    private val mAlphaSeekBar : SeekBar by lazy {
        SeekBar(context).apply {
            // min = 0
            max = 0xFF
            layoutParams = mComponentLayoutParams
            setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener{
                override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
                    alphaValue = progress
                    Timber.d("mAlphaSeekBar progress: $progress, alphaValue:$alphaValue")
                }

                override fun onStartTrackingTouch(seekBar: SeekBar?) {
                }

                override fun onStopTrackingTouch(seekBar: SeekBar?) {
                }
            })
        }
    }

    init {
        orientation = LinearLayout.VERTICAL
        gravity = Gravity.CENTER
        layoutParams = ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT).apply {
            val xPadding = dpToPx(30f).toInt()
            val yPadding = dpToPx(40f).toInt()
            setPadding(xPadding, yPadding, xPadding, yPadding)
        }

        addView(mAlphaSeekBar)
        // 16776943 x 63??
        addView(mColorPickerView)
    }
}

crash log
