How can send images from Android Application to Server? -
i want store images in server via post, images sent sent local storage cell, code asynchronous class in android :
class imageupload extends asynctask<void, void, string>{ @override protected string doinbackground(void... var) { system.out.println(incidentid); httpurlconnection connection = null; dataoutputstream outputstream = null; inputstream inputstream = null; string twohyphens = "--"; string boundary = "*****" + long.tostring(system.currenttimemillis()) + "*****"; string lineend = "\r\n"; string result = ""; int bytesread, bytesavailable, buffersize; byte[] buffer; int maxbuffersize = 1 * 1024 * 1024; string[] q = mcurrentphotopath.split("/"); int idx = q.length - 1; try { file file = new file(mcurrentphotopath); fileinputstream fileinputstream = new fileinputstream(file); url url = new url(url_add_attachment); connection = (httpurlconnection) url.openconnection(); connection.setdoinput(true); connection.setdooutput(true); connection.setusecaches(false); connection.setrequestmethod("post"); connection.setrequestproperty("content-type", "multipart/form-data; charset=utf-8"); connection.setrequestproperty("accept", "application/json"); outputstream = new dataoutputstream(connection.getoutputstream()); outputstream.writebytes(twohyphens + lineend); outputstream.writebytes("content-disposition: form-data; name=\"" + "file" + "\"; filename=\"" + q[idx] + "\"" + lineend); outputstream.writebytes("content-type: " + "image" + lineend); outputstream.writebytes("content-transfer-encoding: binary" + lineend); outputstream.writebytes(lineend); bytesavailable = fileinputstream.available(); buffersize = math.min(bytesavailable, maxbuffersize); buffer = new byte[buffersize]; bytesread = fileinputstream.read(buffer, 0, buffersize); outputstream.write(buffer, 0, buffersize); bytesavailable = fileinputstream.available(); buffersize = math.min(bytesavailable, maxbuffersize); bytesread = fileinputstream.read(buffer, 0, buffersize); outputstream.writebytes(lineend); try { outputstream.writebytes(twohyphens + lineend); //outputstream.writebytes("content-disposition: form-data; name=\"" + key + "\"" + lineend); outputstream.writebytes("content-type: text/plain" + lineend); outputstream.writebytes(lineend); outputstream.writebytes(lineend); //} outputstream.writebytes(twohyphens + twohyphens + lineend); } catch (exception e) { e.printstacktrace(); } int status = connection.getresponsecode(); inputstream in; if(status >= httpstatus.sc_bad_request) in = connection.geterrorstream(); else in = connection.getinputstream(); inputstream = connection.getinputstream(); result = convertstreamtostring(in); fileinputstream.close(); inputstream.close(); outputstream.flush(); outputstream.close(); }catch(exception e){ e.printstacktrace(); } return result; } } the server throws 400 error response send me exception :
