你好,我正在开发一款与安卓相关的应用程序,其中我需要将视频上传到PHP服务器。
我使用HTTPURLConnection
进行上传,但是我遇到了在通知区域显示进度条并更新它的问题。
我已经搜索了近一个星期,但是无法找到任何线索。如果有人知道,请帮助我:
我的代码:
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead;
byte[] buffer;
String urlString = "http://xxxxx/My_path.php";
try {
long total = 0;
int count = 0;
// ------------------ CLIENT REQUEST
UUID uniqueKey = UUID.randomUUID();
fname = uniqueKey.toString();
Log.e("UNIQUE NAME", fname);
FileInputStream fileInputStream = new FileInputStream(
new File(selectedPath));
URL url = new URL(urlString);
conn = (HttpURLConnection) url.openConnection();
int length=selectedPath.length();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\""
+ fname + "" + lineEnd);
dos.writeBytes(lineEnd);
buffer = new byte[8192];
bytesRead = 0;
while ((bytesRead = fileInputStream.read(buffer)) > 0) {
dos.write(buffer, 0, bytesRead);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
Log.e("Debug", "File is written");
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
Log.e("Debug", "error: " + ex.getMessage(), ex);
} catch (IOException ioe) {
Log.e("Debug", "error: " + ioe.getMessage(), ioe);
}
// ------------------ read the SERVER RESPONSE
try {
inStream = new DataInputStream(conn.getInputStream());
String str;
while ((str = inStream.readLine()) != null) {
Log.e("Debug", "Server Response " + str);
}
inStream.close();
} catch (IOException ioex) {
Log.e("Debug", "error: " + ioex.getMessage(), ioex);
}
