Android: Uploading Image on Server with PHP

Uploading Image from android to PHP server

Use below code. It will do the same.

public class UploadImage extends Activity {
    InputStream inputStream;
        @Override
    public void onCreate(Bundle icicle) {
            super.onCreate(icicle);
            setContentView(R.layout.main);

            Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.icon);           ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream); //compress to which format you want.
            byte [] byte_arr = stream.toByteArray();
            String image_str = Base64.encodeBytes(byte_arr);
            ArrayList<NameValuePair> nameValuePairs = new  ArrayList<NameValuePair>();

            nameValuePairs.add(new BasicNameValuePair("image",image_str));

             Thread t = new Thread(new Runnable() {

            @Override
            public void run() {
                  try{
                         HttpClient httpclient = new DefaultHttpClient();
                         HttpPost httppost = new HttpPost("server-link/folder-name/upload_image.php");
                         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                         HttpResponse response = httpclient.execute(httppost);
                         String the_string_response = convertResponseToString(response);
                         runOnUiThread(new Runnable() {

                                @Override
                                public void run() {
                                    Toast.makeText(UploadImage.this, "Response " + the_string_response, Toast.LENGTH_LONG).show();                          
                                }
                            });

                     }catch(Exception e){
                          runOnUiThread(new Runnable() {

                            @Override
                            public void run() {
                                Toast.makeText(UploadImage.this, "ERROR " + e.getMessage(), Toast.LENGTH_LONG).show();                              
                            }
                        });
                           System.out.println("Error in http connection "+e.toString());
                     }  
            }
        });
         t.start();
        }

        public String convertResponseToString(HttpResponse response) throws IllegalStateException, IOException{

             String res = "";
             StringBuffer buffer = new StringBuffer();
             inputStream = response.getEntity().getContent();
             int contentLength = (int) response.getEntity().getContentLength(); //getting content length…..
              runOnUiThread(new Runnable() {

            @Override
            public void run() {
                Toast.makeText(UploadImage.this, "contentLength : " + contentLength, Toast.LENGTH_LONG).show();                     
            }
        });

             if (contentLength < 0){
             }
             else{
                    byte[] data = new byte[512];
                    int len = 0;
                    try
                    {
                        while (-1 != (len = inputStream.read(data)) )
                        {
                            buffer.append(new String(data, 0, len)); //converting to string and appending  to stringbuffer…..
                        }
                    }
                    catch (IOException e)
                    {
                        e.printStackTrace();
                    }
                    try
                    {
                        inputStream.close(); // closing the stream…..
                    }
                    catch (IOException e)
                    {
                        e.printStackTrace();
                    }
                    res = buffer.toString();     // converting stringbuffer to string…..

                    runOnUiThread(new Runnable() {

                    @Override
                    public void run() {
                       Toast.makeText(UploadImage.this, "Result : " + res, Toast.LENGTH_LONG).show();
                    }
                });
                    //System.out.println("Response => " +  EntityUtils.toString(response.getEntity()));
             }
             return res;
        }
}

PHP Code

<?php
    $base=$_REQUEST['image'];
     $binary=base64_decode($base);
    header('Content-Type: bitmap; charset=utf-8');
    $file = fopen('uploaded_image.jpg', 'wb');
    fwrite($file, $binary);
    fclose($file);
    echo 'Image upload complete!!, Please check your php file directory……';
?>

UPDATE

NameValuePair and Http Classes are deprecated so, I've tried this code and it's working for me. Hope that helps!

private void uploadImage(Bitmap imageBitmap){
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    imageBitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);
    byte[] b = stream.toByteArray();
    String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);
    ArrayList<Pair<String, String>> params = new ArrayList<Pair<String, String>>();
    params.add(new Pair<>("image", encodedImage));

    try {
        new AsyncUploader().execute(my_upload_php, getQuery(params));
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
}

private String getQuery(List<Pair<String, String>> params) throws UnsupportedEncodingException{
    StringBuilder result = new StringBuilder();
    boolean first = true;

    for(Pair<String, String> pair : params){
        if(first)
            first = false;
        else
            result.append("&");

        result.append(URLEncoder.encode(pair.first, "UTF-8"));
        result.append("=");
        result.append(URLEncoder.encode(pair.second, "UTF-8"));
    }
    return result.toString();
}

private class AsyncUploader extends AsyncTask<String, Integer, String>
{
    @Override
    protected String doInBackground(String... strings) {
        String urlString = strings[0];
        String params = strings[1];
        URL url = null;
        InputStream stream = null;
        HttpURLConnection urlConnection = null;
        try {
            url = new URL(urlString);
            urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestMethod("POST");
            urlConnection.setDoOutput(true);

            urlConnection.connect();

            OutputStreamWriter wr = new OutputStreamWriter(urlConnection.getOutputStream());
            wr.write(params);
            wr.flush();

            stream = urlConnection.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(stream, "UTF-8"), 8);
            String result = reader.readLine();
            return result;
        }catch (IOException ioe){
            ioe.printStackTrace();
        } finally {
            if (urlConnection != null)
                urlConnection.disconnect();
        }
        return null;
    }

    @Override
    protected  void onPostExecute(String result) {
        Toast.makeText(MakePhoto.this, result, Toast.LENGTH_SHORT).show();
    }
}

Android : Upload image to PHP server

Have you verified that the user apache (or whichever user php is running as) has permissions to write to the directory specified in $file_path?

Put the following code in the same directory as your PHP script is, and then visit it in your web browser.

<?php

$file_path = 'uploads/';

$success = file_put_contents($file_path . "afile", "This is a test");

if($success === false) {
    echo "Couldn't write file";
} else {
    echo "Wrote $success bytes";
}

?>

Does this give a success message or an error message?

If it gives an error message, trying changing the ownership of the uploads directory.

Upload image to web server from Android

you can save the files in server and keep the filename in DB is the preferred solution. Also there is upload limit for every server. You can increase by editing server configuration or using php ini_set.
