To resolve the problem of multiple videos or processes trying to access the same cache, you need a true Singleton. A reliable way would be to do it this way:

object VideoCache {
    private var sDownloadCache: SimpleCache? = null
    private const val maxCacheSize: Long = 100 * 1024 * 1024

    fun getInstance(context: Context): SimpleCache {
        val evictor = LeastRecentlyUsedCacheEvictor(maxCacheSize)
        if (sDownloadCache == null) sDownloadCache = SimpleCache(File(context.cacheDir, "koko-media"), evictor)
        return sDownloadCache as SimpleCache
    }
}

which you can now use:

private val simpleCache: SimpleCache by lazy {
        VideoCache.getInstance(context)
    }
