Uploading image from android to php server is not working properly -

i´m trying upload image using openurlconnection i´m facing problems. java class:

public class upload extends appcompatactivity {     inputstream inputstream;      @override     protected void oncreate(bundle savedinstancestate)    {       super.oncreate(savedinstancestate);       setcontentview(r.layout.activity_upload);        strictmode.enabledefaults();        bitmap bitmap = bitmapfactory.decoderesource(getresources(), r.drawable.sss);       bytearrayoutputstream stream = new bytearrayoutputstream();       bitmap.compress(bitmap.compressformat.png, 90, stream);       byte [] byte_arr = stream.tobytearray();       string encodedimage = base64.encodetostring(byte_arr, base64.default);       string msj = downloadimage(encodedimage);       toast.maketext(getbasecontext(), "mensaje "+msj, toast.length_short).show();     }       public string downloadimage(string tabla)     {       string urlg = "http://192.168.43.98/jober/";        try {           url url = new url(urlg+"upload.php");           httpurlconnection conn = (httpurlconnection) url.openconnection();           conn.setrequestmethod("post");            // para activar el metodo post           conn.setdooutput(true);           conn.setdoinput(true);           dataoutputstream wr = new dataoutputstream(                   conn.getoutputstream());           wr.writebytes("image="+tabla);           wr.flush();           wr.close();            inputstream = conn.getinputstream();           bufferedreader rd = new bufferedreader(new inputstreamreader(is));           string line;           stringbuffer response = new stringbuffer();           while((line = rd.readline()) != null) {               response.append(line);               response.append('\r');           }           rd.close();           return response.tostring();        }         catch(exception e){ return "error";}     } } 

and php code is:

<?php        $base=$_request['image'];     $binary=base64_decode($base);     header('content-type: bitmap; charset=utf-8');     $file = fopen('uploaded_image.png', 'wb');     fwrite($file, $binary);     fclose($file);     echo 'image upload complete!!, please check php file directory……'; ?> 

the problem when check file , looks like:

i looking error i´m not able to.

you have urlencode string before send php, since default base64 decode includes symbols + , =. change

string encodedimage = base64.encodetostring(byte_arr, base64.default); 

to

string encodedimage = urlencoder.encode(base64.encodetostring(byte_arr, base64.default), "utf-8"); 

and go.
