plz me this,i in big trouble.
things have tried :
private static final int pick_from_camera = 1; private static final int pick_from_file = 2; private string imgpath = null; private uri mimagecaptureuri; private string encodedimage; @override public void onclick(view v) { // onregisterbuttonclick();

you can use http mime library(preferable 4.3.3) , http post upload file server.
php server recognize image file required in case.
have created class helps me upload image or file server
public class fileuploadhelper extends asynctask<void, void, void> { private multipartentitybuilder multipartentity; private string url; public fileuploadhelper(string url) { multipartentity = multipartentitybuilder.create(); this.url = url; } @suppresslint("trulyrandom") @override protected void doinbackground(void... arg0) { try { multipartentity.addtextbody("<your string key>", "<string value>"); multipartentity.setmode(httpmultipartmode.browser_compatible); httpclient httpclient; httpclient = new defaulthttpclient(); httpclient.getconnectionmanager().closeexpiredconnections(); httppost httppost = new httppost(url); httppost.setentity(multipartentity.build()); httpresponse response = httpclient.execute(httppost); int responsecode = response.getstatusline().getstatuscode(); string serverresponse = entityutils.tostring(response.getentity()); } catch (exception e) { e.printstacktrace(); } return null; } public void addfile(string key, file newfile) throws filenotfoundexception { if (newfile.exists()) { multipartentity.addbinarybody(key, newfile); } else { throw new filenotfoundexception("no file found @ path " + newfile.getpath()); } } } to use class create object of fileuploader class, call addfile() function , call execute() class extends asynctask. in code have file object
file file = new file(environment.getexternalstoragedirectory(), "tmp_avatar_" + string.valueof(system.currenttimemillis()) + ".jpg"); just pass object addfile().
hope you
