I want to upload a file to net server use the codes. but when the size > 6M ,throw a FATAL EXCEPTION java.lang.OutOfMemoryError
HttpURLConnection conn;
URL url = new URL(mServerUrl);
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", file.getContentType());
conn.setRequestProperty("Connection", "close");
conn.setRequestProperty("Charset", "UTF-8");
conn.connect();
DataOutputStream os = new DataOutputStream(conn.getOutputStream());
int totalSize = 0;
byte[] buffer = new byte[1024];
int len = 0;
while ((len = file.getInStream().read(buffer, 0, 1024)) != -1) {
totalSize += len;
WDLog.i("totalSize = " + totalSize);
os.write(buffer, 0, len);
}
file.getInStream().close();
os.flush();
os.close();
what could i do to solve the question??
thanks

and at
os.write(buffer, 0, len);
this line throw the error.
Upload the file to the server in chunk by chunk basis. example. first upload 1024 bytes of data after getting response from server upload the next 1024 bytes of data and so on until the all the data of the file is uploaded.
