的cocos2d-x的OpenGL上下文在Android失踪（OK与iPhone）

Question

当我退出程序，并重新进入它，我得到了一个错误：

libEGL call to OpenGL ES API with no current context (logged once per thread)  (red warning text) 
libc  Fatal signal 11 (SIGSEGV) at 0x5f012000 (code=2)     (black text) 

和错误文件：（不知道在哪里，但确定如果我不使用这个文件）

    glEnableClientState(GL_TEXTURE_COORD_ARRAY); 
    glEnable(GL_TEXTURE_2D);   

    masked->end(); 

} 

请注意，它适用于iOS，但适用于android崩溃。

编辑::

如果我注释掉的刮开圆/矩形方法的最后一行，没有什么会被吸引，但它不会崩溃。所以问题是行：masked-> end（）？

这恰好是cocos2d-x的错误。固定在新版本v2.x上。 （看起来cocos2d-x会停止更新使用opengl 1.x的1.x版本），因此可悲地不支持iPhone和iPhone 3g。无论如何更新cocos2d-x 2.x现在工作。
