请各位大侠帮忙看一下，这种错误一般在什么情况下出现，现在项目上线了监测到这样一个错误，花好长时间找不到原因，请各位看看，谢了！

IllegalArgumentException此异常表明向方法传递了一个不合法或不正确的参数。你看看传值的方法是否参数不正确。

非法参数

SubForumActivity中你引用了Bitmap的构造函数

java.lang.IllegalArgumentException: width and height must be > 0 说的很清楚，在你传入给Bitmap参数前，进行下width、height的判断

++ 就是非法参数， Width Height值小于0

让我猜猜，长宽获取不对，估计解码的时候用int去读float的值

谢谢各位的帮助，但是让我很不解的是，我的工程里面没有用到是什么Width、Height之类的东西
