NotSerializableException in Android

I verified from the java docs that boolean and byte are serializable. As per the android docs, my class implements the serializable interface. I am not sure why I keep getting the exception. What am I missing here? The class is like this:

public class msgStruct implements Serializable {
    boolean pingPong = false; 
    int msgId = 0;
    byte[] bufferMsg = new byte[100];
}

This is serialized before being sent via a socket to the server, like this:

sendMsgStruct.pingPong = false;
sendMsgStruct.msgId = msgId;
rand.nextBytes(sendMsgStruct.bufferMsg);
try {
    ObjectOutputStream serializeMobile = new ObjectOutputStream(mobileSocket.getOutputStream());
    serializeMobile.writeObject(sendMsgStruct);
    serializeMobile.close();
} catch (IOException e1) {
    e1.printStackTrace();
    return false;
}

The server deserializes like this:

try {
     ObjectInputStream deserializeServer = new ObjectInputStream(clientSocket.getInputStream());
     recvMsgStruct = (msgStruct) deserializeServer.readObject();
     deserializeServer.close();
    } catch (ClassNotFoundException e1) {
      e1.printStackTrace();
    }

I get the exception at the lines where the object is serialized and deserialized.

Is msgStruct an inner class by chance? If so, then try to make it static, or move it to its own java file.
