I want upload videos from my android apps to server.When iam trying to upload the video my apps shows04-23 13:07:41.602: ERROR/dalvikvm-heap(519): Out of memory on a 15607356-byte allocation.I dont know why the error is occuring.My question is
Can we upload video of size upto 50MB using the below code?if anybody knows please help me...

Explained: read() will return you the number of bytes it read or -1 if the end of the stream is reached and no further data can be read. It also fills the first N bytes of buffer with the data it read. The (a = b) != c syntax first assigns b to a, then compares the value to c (here: execute read, assign result to bytesRead, compare to -1). Therefore the loop runs until every byte is read from start to the end of the stream.
After each read the data in buffer is written via write. Since we know from bytesRead how much bytes in buffer are actually newly read bytes we tell write to write only the bytes from 0 to bytesRead. No need to check InputStream.available() (which may even return meaningless results if the length of the stream is not known) or any other method.
Note: changing that to while (bytesRead > 0) introduces a subtle difference. It will stop reading if you read 0 bytes but did not reach the end of the stream. That case is legal although it is pretty safe to assume that it does not happen. You are safer if you use bytesRead >= 0 though.
That means, you run out of memory. Try to reduce your my memory usage by decreasing buffer size:
int maxBufferSize = 2*1024*1024;
even after using this code you will have same error "out of memory" in this case you should use httppost and multipart entity to post your data...

[HttpPost]

{
var httpRequest = HttpContext.Current.Request;
HttpPostedFile file = httpRequest.Files["ProfilePic"];
if (file == null)
throw new EmptyObjectException(ErrorMessageTypes.EmptyObject, jobSeekerId);

}
What actually is happening is- somehow the image is not being sent properly from client. It would be great to have your help on this context. Thanks
I've found the solution. Android HttpUrlConnection is a bit restricted for file uploading sort of things. It has a specific format- if violated it won't work. The format is
--xxxxxxxxxx
Content-Disposition: form-data; name="filetoupload"; filename="helloworld.png"
Content-Type: image/png
Image data
--xxxxxxxxxx--
here 'xxxxxx' part is the one we call boundary. '--' is twoHyphens. And the lineEnd must be put in the right place with right amount. So in my code it should be
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"ProfilePic\"; filename=\""+ file.getPath() + "\"" + lineEnd);
outputStream.writeBytes("Content-Type: image/png" + lineEnd);
outputStream.writeBytes(lineEnd);
FileInputStream fileInputStream;
fileInputStream = new FileInputStream(file.getPath());
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// Read file
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
try{
outputStream.write(buffer, 0, bufferSize);
} catch (OutOfMemoryError e) {
e.printStackTrace();
Log.d("Exception occured", "Out of memory");
return "out of memory";
}
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

I am working on an android app which let's user record a video 30sec long and then I need to save this video file on the server. I am using a web service which accepts the video file in the byteArray format.
So, I don't know how to convert and compress .mp4 file and then send it to web service over the wire. Please help...

I want to upload images to a server. I used http://katharnavas.blogspot.com/2009/10/upload-files-from-mobile.html code and other methods, but phone sometimes fail, and analog machine always run well. Can you help me to analyze the cause of the error and whether I need some setting? Thank you.

can anyone suggest some idea to solve this.
I think error happened in follow line because DataOutputStream size is exceeds VM budget when you write
dos.write(buffer, 0, bufferSize);
