expected member declaration

[hemo7f12]

Hello,
I'm trying to use the library to take a screenshot but there is issue with the code here

    Instacapture.capture(this, object : SimpleScreenCapturingListener() {
        override fun onCaptureComplete(bitmap: Bitmap) {
            //Your code here..

        }
    })

// or in Rx way
    Instacapture.captureRx(this).subscribe { bitmap ->
        //Your code here..
    }

it says "expected member declaration " in these two lines ( Instacapture.captureRx(this).subscribe ) and ( Instacapture.capture(this, object : SimpleScreenCapturingListener() {
)

and for (bitmap )it says unresolved reference
