Subir imágenes al servidor android

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); photoPickerIntent.setType("image/*"); startActivityForResult(photoPickerIntent, 1); 

CÓDIGO ANTERIOR PARA SELECCIONAR LA IMAGEN DE LA GALERÍA

 @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 1) if (resultCode == Activity.RESULT_OK) { Uri selectedImage = data.getData(); String filePath = getPath(selectedImage); String file_extn = filePath.substring(filePath.lastIndexOf(".") + 1); image_name_tv.setText(filePath); try { if (file_extn.equals("img") || file_extn.equals("jpg") || file_extn.equals("jpeg") || file_extn.equals("gif") || file_extn.equals("png")) { //FINE } else { //NOT IN REQUIRED FORMAT } } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } public String getPath(Uri uri) { String[] projection = {MediaColumns.DATA}; Cursor cursor = managedQuery(uri, projection, null, null, null); column_index = cursor .getColumnIndexOrThrow(MediaColumns.DATA); cursor.moveToFirst(); imagePath = cursor.getString(column_index); return cursor.getString(column_index); } 

AHORA ENVIAR LOS DATOS USANDO DATOS DE FORMULARIO MULTIPART

 HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("LINK TO SERVER"); 

DATOS DE FORMULARIO

 MultipartEntity mpEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); if (filePath != null) { File file = new File(filePath); Log.d("EDIT USER PROFILE", "UPLOAD: file length = " + file.length()); Log.d("EDIT USER PROFILE", "UPLOAD: file exist = " + file.exists()); mpEntity.addPart("avatar", new FileBody(file, "application/octet")); } 

FINALMENTE POST DATA TO SERVER

 httppost.setEntity(mpEntity); HttpResponse response = httpclient.execute(httppost);

Código php para manejar la imagen de carga y también crear la imagen de base64 datos codificados

 <?php error_reporting(E_ALL); if(isset($_POST['ImageName'])){ $imgname = $_POST['ImageName']; $imsrc = base64_decode($_POST['base64']); $fp = fopen($imgname, 'w'); fwrite($fp, $imsrc); if(fclose($fp)){ echo "Image uploaded"; }else{ echo "Error uploading image"; } } ?> 

Utilice debajo del código que le ayuda …

  BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 4; options.inPurgeable = true; Bitmap bm = BitmapFactory.decodeFile("your path of image",options); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bm.compress(Bitmap.CompressFormat.JPEG,40,baos); // bitmap object byteImage_photo = baos.toByteArray(); //generate base64 string of image String encodedImage =Base64.encodeToString(byteImage_photo,Base64.DEFAULT); //send this encoded string to server
