06-14 18:27:46.186 4948-4974/? E/GamesNativeSDK? Could not register one or more required Java classes.

Earlier in the log, there should be some errors about registering java classes? To fix this make sure you have the latest play services SDK (in SDK manager, it is in the "Extras" section). and run the plugin setup again, Window > Google Play Games > Setup > Android Setup ...

[GeorgeDominic]

ok will try and see

[GeorgeDominic]

yes that worked well, I had to run plugin setup again. signin working now but I have an issue with opening saved games logcat: 06-15 15:08:28.545 21606-21623/?

How to open a saved game which does not exist, for example a someone sigining into google play services for the first time. normally you would use Games.Snapshot.open(apiClient, filename, createIfNotFound); createIfNotFound will do the job but unity plugin has different methods and different ways of handling thing I think.

[claywilkinson]

From the log, it looks like SDKs may need to be updated? There are a lot of methods that look missing.

In the C++ SDK (and the Unity plugin), createIfNotFound is effectively always true, so you can call it with a filename that does not exist and open will succeed.

I am trying to convert an object to byte array using the following C# code, but it is not working in Android, can you tell me what to do please. I want to save the obj to the GPS cloud

public static byte[] ObjectToByteArray(Object obj) { BinaryFormatter bf = new BinaryFormatter(); using (var ms = new MemoryStream()) { bf.Serialize(ms, obj); return ms.ToArray(); } } // Convert a byte array to an Object public static InventoryItems ByteArrayToObject(byte[] arrBytes) { using (var memStream = new MemoryStream()) { var binForm = new BinaryFormatter(); memStream.Write(arrBytes, 0, arrBytes.Length); memStream.Seek(0, SeekOrigin.Begin); InventoryItems obj =(InventoryItems) binForm.Deserialize(memStream); return obj; } }

[claywilkinson]

The way is done in the NearbyDroids sample is:

       private static BinaryFormatter bf = new BinaryFormatter();

        MemoryStream m = new MemoryStream();
        bf.Serialize(m, msg); 
        m.Flush();
        return m.ToArray();`

Then to deserialize:

        MemoryStream ms = new MemoryStream(data);
        GameDataMessage msg = bf.Deserialize(ms) as GameDataMessage;

yup saved games working just fine I am able to serialize and deserialize objs, very cool thank you. please close this issue
