ExifInterface 1.3.3 returns "0/1 0/1" for longitude and latitude values

Question

fun ExifInterface.getTags(): HashMap<String, String> {
        val mAttributes = mAttributes()

        var map = HashMap<String, String>()
        if (mAttributes is Array<*>) {
            val arrayOfMapAux = mAttributes as Array<HashMap<String, *>>
            arrayOfMapAux.indices
                .flatMap { mAttributes[it].entries }
                .forEach { map[it.key] = this.getAttribute(it.key)!! }
        } else if (mAttributes is HashMap<*, *>) {
            map = mAttributes as HashMap<String, String>
        }

        val latLonArray = FloatArray(2)
        if (this.getLatLong(latLonArray)) {
            val lat = latLonArray[0].toString()
            val lng = latLonArray[1].toString()
            Log.d("imgGpsTracker", "lat = $lat & lng = $lng")
        }
        Log.d("imgGpsTracker", "lat = ${latLonArray[0].toString()} & lng = ${latLonArray[1].toString()}")
        return map
    }

Im trying to get the gps location of the images, but all i got is 0/1 0/1 0/1. Images which doesn't have gps location returns null value. checkout logcat lines from here
