我正在使用方法“uploadAvatar”在我的ubuntu服务器上使用android 4.1和php上传nginx和php-fpm 5.3上的图像。照片被挑选或从相机拍摄，然后被裁剪，保存在文件夹中，然后上传到服务器。
我可以使用图库应用程序在正确的路径中看到手机中的图像。我用图像的绝对路径调用方法然后应用程序开始上传图像，服务器响应200，图像在服务器上但是坏了，我无法用浏览器读取图像。

String fileName = sourceFileUri;

String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
ProgressDialog_.dismiss();
Log.e("uploadFile", "Source File not exist :" + sourceFile.getAbsolutePath());
runOnUiThread(new Runnable() {
public void run() {
//messageText.setText("Source File not exist :"+uploadFilePath + "" + uploadFileName);

这是服务器端PHP脚本：
图片已上传但已损坏，在设备上可以正常... 大约2天我正在研究这个问题，有人可以帮助我吗？
您可以在此处看到损坏的图片：http://putp.about42.com/testimage.png
更新：
构建此方法我遵循here的教程：
我在行中发现错误：
dos.writeBytes("Content-Disposition: form-data; name="uploaded_file";filename=""
+ fileName + """ + lineEnd);
我改变了这个：
dos.writeBytes("Content-Disposition: form-data; name=uploaded_file;filename=" + fileName + " + lineEnd");
也许破碎的图像依赖于此...我很抱歉，但我不知道这行代码是做什么的......

此代码工作正常！

我在代码上做了一些修改，现在它就像一个魅力！
