Answer 1

you can try with only saving the name like "joe_pic" and can get this way

private void showImage() {
    String uri = "drawable/icon";

    // int imageResource = R.drawable.icon;
    int imageResource = getResources().getIdentifier(uri, null, getPackageName());

    ImageView imageView = (ImageView) findViewById(R.id.myImageView);
    Drawable image = getResources().getDrawable(imageResource);
    imageView.setImageDrawable(image);
}

but if you have already added "R.drawable.joe_pic" complete can use String.split to get 3 rd string part
