今天花费了一天的时间来解决这个bug. 这种在程序运行期间出现的问题比较棘手,如果再没有规律的话就更难解决. 还好这个bug是由规律的,也就是说在程序执行半个小时左右后就会因为此异常而导致程序退出:那么在网上找了下原因,无非是说一下几点: 1.把业务放在子线程中去完成,然后通过handler来更新界面 2.通过runOnUiThread的方法来实现 再补充一点就是:优化代码,将不需要重复执行的代码执行一次就ok了,特别是需要绘制UI的代码更不能随便放在重复执行的地方 一.bug现场还原 我的程序…

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. 我的出现这个原因是,jquery的async: false,导致 async:true,(默认),异步方式,$.Ajax执行后,会继续执行ajax后面的脚本,直到服务器端返回数据后,触发$.Ajax里的success方法,这时候执行的是两个线程. a…
Xcode打印栏出现如下警告: Main Thread Checker: UI API called on a background thread 这个是什么错误呢? 其实这并不一定是错误,也可以理解为一种警告,说他不是错误,是因为它不一定会影响你的代码功能,可能对你的实现功能毫无影响. 那么它的含义是这样: 这是Xcode 9的新特性:主线程检测器(Main Thread Checker). 出现的时候意味着:本来需要在主线程执行的代码 被你放在了子线程里边执行. 那么我们解决的话,只需要检查…

是Java程序的入口方法,JVM在运行程序时,会首先查找main()方法. public是权限修饰符,表明任何类或对象都可以访问这个方法: static表明main()方法是一个静态方法,即方法中的代码时存储在静态区的,只要类被加载后,就可以使用该方法而不需要通过实例化对象来访问,可以直接通过 类名.main() 直接访问: void表明方法没有返回值: main是JVM识别的特殊分方法名,是程序的入口方法: 方法的参数为字符串数组,字符串数组参数args为开发人员在命令行状态下与程序交互提供了…
1.区别是main()函数是否有返回值.2.void定义的函数没有返回值,int定义的函数返回整型值.3.void,字面意思是"无类型",常用在程序编写中对定义函数的参数类型.返回值.函数中指针类型进行声明,有注释和限制程序的作用. 4.标准的main函数格式为:int main(int argc, char *argv[]);即返回值为整型,带两个参数,argc为命令行参数的个数,argv为指针数组,前argc个指针为参数列表,最后一个指针值为NULL.…
