Pracuję nad podstawową aplikacją aparatu. Mogę zrobić zdjęcie i zobaczyć je w mojej aplikacji. Ale chcę zobaczyć moje zdjęcie w galerii asynchroniczne. Po ponownym uruchomieniu telefonu widzę moje zdjęcie w galerii.

Przykładowy kod.

public class PhotosActivity extends Fragment implements View.OnClickListener {

    private final int REQUEST_CODE   = 100;

    private Button fotobutton;
    private ImageView foto_image;
    private static final String IMAGE_DIRECTORY_NAME = "OlkunMustafa";
    public static final int MEDIA_TYPE_IMAGE = 1;

    private Uri fileUri;
    // Directory name to store captured images and videos

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView       = inflater.inflate(R.layout.photos_activity,container,false);
        fotobutton          = (Button) rootView.findViewById(R.id.fotobutton);
        foto_image          = (ImageView) rootView.findViewById(R.id.foto_image);

        fotobutton.setOnClickListener(this);

        return rootView;
    }

    @Override
    public void onClick(View v) {
        if( v == fotobutton) {
            Intent photo_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            fileUri = getOutputMediaFile(MEDIA_TYPE_IMAGE);
            photo_intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

            startActivityForResult(photo_intent,100);
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(resultCode == getActivity().RESULT_OK)
        {
            BitmapFactory.Options options = new BitmapFactory.Options();
            final Bitmap bitmap = BitmapFactory.decodeFile(fileUri.getPath(),
                    options);
            foto_image.setImageBitmap(bitmap);

            Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
            Uri contentUri = getOutputMediaFile(MEDIA_TYPE_IMAGE);
            mediaScanIntent.setData(contentUri);
            getActivity().sendBroadcast(mediaScanIntent);
        }
    }

    private static Uri getOutputMediaFile(int type) {

        // External sdcard location
        File mediaStorageDir = new File(
                Environment
                        .getExternalStorageDirectory(),
                IMAGE_DIRECTORY_NAME);

        // Create the storage directory if it does not exist
        if (!mediaStorageDir.exists()) {
            if (!mediaStorageDir.mkdirs()) {
                Log.d(IMAGE_DIRECTORY_NAME, "Oops! Failed create "
                        + IMAGE_DIRECTORY_NAME + " directory");
                return null;
            }
        }

        // Create a media file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
                Locale.getDefault()).format(new Date());
        File mediaFile;
        if (type == MEDIA_TYPE_IMAGE) {
            mediaFile = new File(mediaStorageDir.getPath() + File.separator
                    + "IMG_" + timeStamp + ".jpg");
        } 
        else {
            return null;
        }

        return Uri.fromFile(mediaFile);
    }
}

Jak mogę to zrobić?
