Android 安卓上传删除字节
我正在尝试从我的android手机(三星Galaxy s2)上传4.1.2版的视频 我已经配置了一个apache服务器来承载上传的视频。我的问题是:每次我从手机上传视频时,我都有一个损坏的文件。服务器上的文件比手机文件少几个字节。它不是来自服务器,因为我使用html表单做了一些测试,一切都很顺利。所以我猜,它来自我的代码,但我就是不知道在哪里。谁能帮帮我吗,我已经花了好几天时间了 这是我的代码: @凌驾 公共布尔上传文件(){Android 安卓上传删除字节,android,file,video,upload,Android,File,Video,Upload,我正在尝试从我的android手机(三星Galaxy s2)上传4.1.2版的视频 我已经配置了一个apache服务器来承载上传的视频。我的问题是:每次我从手机上传视频时,我都有一个损坏的文件。服务器上的文件比手机文件少几个字节。它不是来自服务器,因为我使用html表单做了一些测试,一切都很顺利。所以我猜,它来自我的代码,但我就是不知道在哪里。谁能帮帮我吗,我已经花了好几天时间了 这是我的代码: @凌驾 公共布尔上传文件(){ HttpURLConnection=null; DataOutput
