Android 无法在后台播放gif

我正在尝试在我的应用程序的背景中播放gif。我试过Glide，但我搞不清楚安装过程。我试图制作一个动画xml，但只能得到要显示的第一帧。目前正在尝试使用PlayGifView，但出现渲染错误，我的应用程序崩溃。如果有人对这些过程有更好的经验，请帮助我将其付诸实施。另外，请尽可能多地将代码保存在Kotlin中，因为我认为一些错误可能来自尝试从Java转换

主要活动

val bgGif = findViewById<PlayGifView>(R.id.viewGif)
    bgGif.setImageResource(R.drawable.background_gif)

val bgGif=findviewbyd（R.id.viewGif）
bgGif.setImageResource（R.drawable.background\u gif）
