问题:
在AppDelegate::applicationWillEnterForeground()代码中显示了一个对话框,结果从后台切换会前台时,出现
call to OpenGL ES API with no current context (logged once per thread)错误。
解决:
Don't call it inAppDelegate::applicationWillEnterForeground
. Because OpenGL context will be lost when enter to background. At this time OpenGL context may not be re-create by Android system. So,please do the operation after it is totally enter foreground.(摘自网络)
在AppDelegate::applicationWillEnterForeground中启动一个定时器,延时一段时间(0.1,具体时间可能需要使用不同手机测试,确定)再显示对话框,结果就可以。
