Open an image with Android Gallery

Question

I need to open a specific image in Android Gallery, but I tried some codes with no success. This is my code:

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse( "file:///Download/screenshot.jpg"), "image/*");
startActivity(intent);

It seems the Android Gallery is open but with no image, it show a black screen.

I'm trying my app in a Samsung Galaxy Nexus with ICS 4.0

Hope anyone can help me.

Thanks, Víctor.

Usew Button And EditID To "btnLoadPicture" And ImageView ID "imgView" Use THe Following And Try Again

private static int RESULT_LOAD_IMAGE = 1;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Button btnLoadPicture = (Button) findViewById(R.id.buttonLoadPicture);

    btnLoadPicture.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

            startActivityForResult(i, RESULT_LOAD_IMAGE);

        }
    });
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();
        // String picturePath contains the path of selected Image
        ImageView imageView = (ImageView) findViewById(R.id.imgView);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
    }
}
