NoSuchMethodError : Landroid / util / SparseArray 클래스에 Z가 포함 된 가상 메서드가 없습니다.

Question

1. 내 앱에서 다음 사진을 위해 스 와이프 할 때마다 앱이 다운되고 무엇이 잘못되었는지 모르겠습니다.

2.이 문제가 제대로 작동하기 전에 Android 30으로 업데이트 한 후 발생합니다.

java.lang.NoSuchMethodError : Landroid / util / SparseArray 클래스에 Z가 포함 된 가상 메소드가 없습니다. 또는 수퍼 클래스 ( 'android.util.SparseArray'선언이 /system/framework/framework.jar!classes2.dex에 표시됨)

사용하다 containsKey

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