我得到了一个关于权限的错误,但是我已经在清单文件上设置了所需的权限,所以我不知道我做错了什么,或者我必须修复什么,有人能解释一下情况吗

此外,我也不理解关于doinbackground的一些错误,是因为许可错误,我在那里也会出错,还是我做错了什么

编辑#1:

似乎我通过您提供给我的链接的权限解决了这个问题,但现在看来我在weatherview类的doinbackground中出现了致命的异常

编辑#2: 当我使用清单1时,我得到了错误输出1,这给了我一个权限错误,但当我使用清单2时,这消除了权限错误,我得到了一个标记错误:/

编辑#3: 已更新错误输出和清单文件,以匹配当前文件输出
