I am trying to get the progress of the actual file upload using HttpPost. I have a stable solution so far (that i found here in SO) that has a progress but after uploading large files i realized it only counts the bytes written to the output buffer NOT the post transfer progress. I would like to somehow get the progress of the actual "post". Can someone explain how I can achieve this using what I worked so hard to get so far? Most of the solutions I have found online are only counting bytes written to output buffer (which is good enough for small files but not when transferring large files).
public static String postFile(final Context context, String fileName) throws Exception {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://my.url/");
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
final File file = new File(fileName);
final long totalSize = file.length();
FileBody fb = new FileBody(file);
builder.addPart("uploaded_file", new FileBody(new File(fileName)));
final HttpEntity yourEntity = builder.build();
int progressPercent = 0;
class ProgressiveEntity implements HttpEntity {
@Override
public void consumeContent() throws IOException {
yourEntity.consumeContent();
}
@Override
public InputStream getContent() throws IOException,
IllegalStateException {
return yourEntity.getContent();
}
@Override
public Header getContentEncoding() {
return yourEntity.getContentEncoding();
}
@Override
public long getContentLength() {
return yourEntity.getContentLength();
}
@Override
public Header getContentType() {
return yourEntity.getContentType();
}
@Override
public boolean isChunked() {
return yourEntity.isChunked();
}
@Override
public boolean isRepeatable() {
return yourEntity.isRepeatable();
}
@Override
public boolean isStreaming() {
return yourEntity.isStreaming();
} // CONSIDER put a _real_ delegator into here!
@Override
public void writeTo(OutputStream outstream) throws IOException {
class ProxyOutputStream extends FilterOutputStream {
public ProxyOutputStream(OutputStream proxy) {
super(proxy);
}
public void write(int idx) throws IOException {
out.write(idx);
}
public void write(byte[] bts) throws IOException {
out.write(bts);
}
public void write(byte[] bts, int st, int end) throws IOException {
out.write(bts, st, end);
}
public void flush() throws IOException {
out.flush();
}
public void close() throws IOException {
out.close();
}
} // CONSIDER import this class (and risk more Jar File Hell)
class ProgressiveOutputStream extends ProxyOutputStream {
long totalSent;
public ProgressiveOutputStream(OutputStream proxy) {
super(proxy);
totalSent = 0;
}
public void write(byte[] bts, int st, int end) throws IOException {
// end is the amount being sent this time
// st is always zero and end=bts.length()
totalSent += end;
int progress = (int) ((totalSent / (float) totalSize) * 100);
out.write(bts, st, end);
}
}
yourEntity.writeTo(new ProgressiveOutputStream(outstream));
}
};
ProgressiveEntity myEntity = new ProgressiveEntity();
post.setEntity(myEntity);
//Output to buffer is complete at this point!
HttpResponse response = client.execute(post);
String jsonResponseStr = getContent(response);
Log.d("MYTAG",jsonResponseStr);
return jsonResponseStr;
}
In my receiving script on the remote server, I am only echo-ing a string so that I can send an immediate response (no file/database processing at all) and the response from server still takes a very long time. I strongly believe at this point the transfer happens after write to buffer completes.
Since I don't see any solution for this, I suppose the answer is to use a spinning animation without a progress percent. Since nothing can be done until the transmission is complete anyway. Oh well... atleast it solved my problem.
