Any update about this issue?

[glennawatson]

Chris Pulman and myself are bringing across the changes we made in our incubator program ReactiveMarbles.CacheDatabase to akavache.

Should fix this type of issue.

That would be great @glennawatson, thank you very much for the prompt reply!

Still encountering the issue on latest versions of akavache, any workaround or fix ?

[ChrisPulman]

I will try to find a resolution after I return from Australia, there has been a few changes in the way the core Sqlite package which may have affected the operation in some ways.

With this code at launch of the maui ios app I was able to retrieve the data saved by xamarin version. But still struggling with android.

var fs = Locator.Current.GetService<IFilesystemProvider>() ??
                     throw new InvalidOperationException(
                         "Failed to initialize Akavache properly. Do you have a reference to Akavache.dll?");

            var userAccount = new Lazy<IBlobCache>(() =>
            {
                var directory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.UserProfile), "Library/Application Support", BlobCache.ApplicationName, "BlobCache");
                

                if (directory is null || string.IsNullOrWhiteSpace(directory))
                {
                    throw new InvalidOperationException(
                        "There is a invalid directory being returned by the file system provider.");
                }
                

                fs.CreateRecursive(directory).SubscribeOn(BlobCache.TaskpoolScheduler).Wait();
                return new SqlRawPersistentBlobCache(Path.Combine(directory, "userblobs.db"),
                    BlobCache.TaskpoolScheduler);
            });
            Locator.CurrentMutable.Register(() => userAccount.Value, typeof(IBlobCache), "UserAccount");
