我有一个问题,我有这样的源代码
public int uploadFile(String sourceFileUri) {
SharedPreferences myPref = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
String upLoadServerUri = new String(myPref.getString("serverURL", Constants.URL)+"/upload.php");
String fileName = picturePath;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(picturePath);
如何在上传前重命名 图片路径上的文件 。谢谢你
