Issue

Need help to fix this or any suggestion which can help here to fix SimpleCache outofmemory issue.

I also tried the LeastRecentlyUsedCacheEvictor but by that way offline videos were not getting played when maxBytes gets exceeded.

I am not able to reproduce this issue in my device, got this issue from crashlytics.

Attaching the stack trace for the crash below:

Fatal Exception: java.lang.OutOfMemoryError: Failed to allocate a 120 byte allocation with 1468512 free bytes and 1434KB until OOM, target footprint 536870912, growth limit 536870912; giving up on allocation because <1% of heap free after GC.

Attaching the code for creating simple cache object:

val cookieManager = CookieManager()
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ORIGINAL_SERVER)
CookieHandler.setDefault(cookieManager)
val standaloneDatabaseProvider = StandaloneDatabaseProvider(context)
val downloadContentDirectory = File(context.filesDir.absolutePath + "/" + APP_NAME + "/Videos")
val simpleCache = SimpleCache(
    downloadContentDirectory, NoOpCacheEvictor(), standaloneDatabaseProvider
)
val upstreamFactory =
    DefaultDataSource.Factory(context, dataSourceFactory)
cacheDataStoreFactory = CacheDataSource.Factory()
    .setCache(simpleCache)
    .setUpstreamDataSourceFactory(upstreamFactory)
    .setCacheWriteDataSinkFactory(null)
    .setFlags(CacheDataSource.FLAG_IGNORE_CACHE_ON_ERROR)
downloadManager = DownloadManager(
    context,
    standaloneDatabaseProvider,
    simpleCache,
    ResolvingDataSource.Factory(dataSourceFactory, resolver),
    Executors.newFixedThreadPool(12) 
)
