NoSuchMethodError：类 Landroid/util/SparseArray 中没有包含 (I)Z 的虚拟方法；

Question

1.每当我在应用程序中滑动查看下一张图片时，应用程序就会崩溃，我不知道出了什么问题

2.更新到Android 30之后出现此问题，然后才能正常工作

java.lang.NoSuchMethodError：类 Landroid/util/SparseArray 中没有包含(I)Z 的虚拟方法；或其超类（“android.util.SparseArray”的声明出现在 /system/framework/framework.jar!classes2.dex 中）

class PostViewFragment : DialogFragment() {
private var player: SimpleExoPlayer? = null
private lateinit var mediaDataSourceFactory: DataSource.Factory
//var post: FeedNodeModel? = null

    val view = inflater.inflate(R.layout.fragment_post_view, container, false)

    //post = arguments?.getSerializable("post") as FeedNodeModel?

                        isFirstLoad = false

                    return fragment
                }

                override fun getCount(): Int = post?.feedNodeModel?.size!!

                }

                override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) {

                }

                @RequiresApi(Build.VERSION_CODES.R)
                override fun onPageSelected(position: Int) {
                    if (post?.feedNodeModel?.get(currentPos)?.__typename == "GraphVideo") {
                        registeredFragments[currentPos]?.onPause()
                    }

                    currentPos = position
                    view.txt_pager_count.text = "${currentPos+1}/${post?.feedNodeModel?.size}"

                    if (registeredFragments.contains(position)) {
                        registeredFragments[position]?.loadVideo()
                    }
                }
            })

            view.viewpager.visibility = View.VISIBLE
            view.img_post.visibility = View.GONE
            view.playerView.visibility = View.GONE
        }
    }

应用程序在此行崩溃

 if (registeredFragments.contains(position)) {
                        registeredFragments[position]?.loadVideo()
                    }

Answer 1

使用containsKey

/** Returns true if the collection contains [key]. */
inline fun <T> SparseArray<T>.containsKey(key: Int) = indexOfKey(key) >= 0
