	override fun onCreate(savedInstanceState: Bundle?) {
		super.onCreate(savedInstanceState)
		binding = ActivitySplashBinding.inflate(layoutInflater)
		setContentView(binding.root)

		Glide.with(this).load(R.drawable.weathericon).into(binding.imageView)

		activityScope.launch {
			delay(3000)
			startActivity(Intent(this@SplashActivity,MainActivity::class.java))
			finish()
		}
