java.Ио.FileNotFoundException в android

Я выбираю изображение из галереи с помощью кода

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.gallery);

    Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(i, SELECT_PICTURE);
}

public void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
    Bitmap bitmap = null;
    switch (requestCode) {
    case SELECT_PICTURE:
        if (resultCode == RESULT_OK) {
            Uri selectedImage = imageReturnedIntent.getData();
            try {
                bitmap = decodeUri(selectedImage);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
            MyApplicationGlobal.bitmap = bitmap;
            MyApplicationGlobal.imageUri = selectedImage.toString();
            Log.v("selectedImage", "selectedImage: " + selectedImage.getPath());

            Intent intentUpload = new Intent(GalleryActivity.this, UploadActivity.class);
            startActivity(intentUpload);
            finish();
        }
    }

затем я пытаюсь загрузить это изображение, позвонив в веб-службу 

MultipartEntity reqEntity = new MultipartEntity();
    try {
        reqEntity.addPart("email", new StringBody(email));
        Log.v("in uploadImageUsingMultiPart", "imagePath: " + MyApplicationGlobal.imageUri);
        reqEntity.addPart("name", new FileBody(new File(MyApplicationGlobal.imageUri)));
        reqEntity.addPart("img_desc", new StringBody(img_desc));
        reqEntity.addPart("amount", new StringBody(amount));
        reqEntity.addPart("request_type", new StringBody("INSERT"));
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }

но я получаю ошибку java.io.FileNotFoundException

Log cat является

вызовите этот метод, передайте ему selectedUri, взамен вы получите путь, который хотите

public String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

просто обновление, так как managedQuery устарел.

private String getPath(Uri uri) {
    String[]  data = { MediaStore.Images.Media.DATA };
    CursorLoader loader = new CursorLoader(context, uri, data, null, null, null);
    Cursor cursor = loader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

потому что content:/media/external/images/media/526 Не файл. Это URI-адрес медиа-провайдера. Если вы хотите, чтобы файл проверил этот вопрос SO:

получить имя файла и путь от URI из mediastore
