'我已经写了这个代码加载我的Android应用程序的屏幕。但每当我安装在我的手机上，我的加载屏幕的fps非常低，似乎有2-3 fps加载屏幕是一个gif文件。

class splash_screen:AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_splash_screen)
        val gifImageView = findViewById<ImageView>(R.id.loading_gif)
        Glide.with(this).asGif().load(R.drawable.loading_gif).into(gifImageView)
        val background = object : Thread() {
            override fun run() {
                try {
                    Thread.sleep(5000)
                    val intent = Intent(baseContext, MainActivity::class.java)
                    startActivity(intent)
                } catch (e: Exception) {
                    e.printStackTrace()
                }
            }
        }
        background.start()
    }
}
