Hai to all,

I am developing a sample animation application. while i run this application it shows the following errors. I don''t know why this error was occured. The application usage memory was increases simultaneously while running the application. How to solve this error. If anybody had the solution for this error please reply this post.

推荐答案

代码在哪里?查看堆栈跟踪-您是否可以使用图像(并且可以访问)?

Where''s the code? Looking at the stack trace - is you image available (and accessible)?

您发布了堆栈跟踪，而不是错误.您没有发布代码.我看不到没有代码和错误消息，没有人能提供帮助.

You posted a stack trace and not an error. You posted no code. I don''t see how anyone can help without both code and the error message.
