- Make sure that input stream is seekable

[doubleday]

I guess I'm not using a pattern which prevents my current issue but when I'm registering sprite maps with

CCSpriteFrameCache.AddSpriteFramesWithFile

I get an exception on Android. The plist file is opened via TitleContainer.OpenStream and this returns a non-seekable stream.

Microsoft.Xna.Framework.TitleContainer.OpenStream (name="Content/tiles/tiles.plist") in ...cocos2d-xna/MonoGame/MonoGame.Framework/TitleContainer.cs:144
Cocos2D.CCContentManager.InternalLoad<Cocos2D.PlistDocument> (assetName="tiles/tiles.plist", path="tiles/tiles.plist", weakReference=false) in ...cocos2d-xna/cocos2d/Platform/CCContentManager.cs:302
Cocos2D.CCContentManager.Load<Cocos2D.PlistDocument> (assetName="tiles/tiles.plist", weakReference=false) in ...cocos2d-xna/cocos2d/Platform/CCContentManager.cs:230
Cocos2D.CCContentManager.Load<Cocos2D.PlistDocument> (assetName="tiles/tiles.plist") in ...cocos2d-xna/cocos2d/Platform/CCContentManager.cs:185
Cocos2D.CCSpriteFrameCache.AddSpriteFramesWithFile (pszPlist="tiles/tiles.plist") in ...cocos2d-xna/cocos2d/sprite_nodes/CCSpriteFrameCache.cs:192

Local vars in PlistDocument looks like this:

public void LoadFromXmlFile(Stream data)

this                {Cocos2D.PlistDocument}                                         Cocos2D.PlistDocument
data                {Android.Runtime.InputStreamInvoker}                            Android.Runtime.InputStreamInvoker
base                {System.IO.Stream}                                              System.IO.Stream

CanSeek             false                                                           bool
CanWrite            false                                                           bool
Length              System.NotSupportedException: Operation is not supported.       
Position            System.NotSupportedException: Operation is not supported.       
Non-public members                                                                  
magicHeader         (null)                                                          System.Byte[]

Simple fix is attached.

BTW: I've seen that MonoGame is doing this in for Android at another place. I'm using the same code. Just search for the comment (which makes no sense here) ...

ha! Wonder why we never had seen that problem manifest before. Thanks!
