Java: Create Drawable from UTF8 String

I have the following code:

public void onSuccess(String response) {
    Log.i("EOH",response);
    Drawable d = null;
    Object content=response.getBytes();
    InputStream is = (InputStream)content;
    d = Drawable.createFromStream(is, "src");

    ImageView captcha = (ImageView)findViewById(R.id.imageView2);
    captcha.setImageDrawable(d);
}

Here is the response string I'm getting (from LogCat):

As you can see, I'm trying to convert a String called 'response' to a Drawable object. Trouble is, the image is always blank!

Does anyone 开发者_如何转开发know of any way I might be able to fix this?

Many thanks in advance,

Edit:

This didn't work either ;(

@Override
public void onSuccess(String response) {
    Log.i("EOH",response);          
    ByteArrayInputStream bis = new ByteArrayInputStream(response.getBytes());
    Bitmap bm=BitmapFactory.decodeStream(bis);

    ImageView imgView = (ImageView)findViewById(R.id.imageView2);
    imgView.setImageBitmap(bm);
}

Try this:

BitmapDrawable drawable = BitmapFactory.decodeFile(response);

Or you could do the following, if you don't need it to be Drawable.

Bitmap bm = BitmapFactory.decodeFile(response);
ImageView captcha = (ImageView)findViewById(R.id.imageView2);
captcha.setImageBitmap(bm);

EDITED

For online files, you can use this:

BitmapFactory.decodeStream(is)

Here's the full function I'm using (doesn't work...):

private void captchaLoad() {
         AsyncHttpClient myClient = new AsyncHttpClient();
         PersistentCookieStore myCookieStore = new PersistentCookieStore(context);
         myClient.setCookieStore(myCookieStore);
         RequestParams params = new RequestParams();

         myClient.post("http://www.extremetech.com/wp-content/uploads/2011/08/amd-logo-106x59.jpg", params, new AsyncHttpResponseHandler() {
            @Override
            public void onStart() {

            }

            @Override
            public void onSuccess(String response) {
                Log.i("EOH",response);

                ByteArrayInputStream bis = null;
                try {
                    bis = new ByteArrayInputStream(response.getBytes("UTF8"));
                } catch (UnsupportedEncodingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                Bitmap bm=BitmapFactory.decodeStream(bis);

                ImageView imgView = (ImageView)findViewById(R.id.imageView2);
                imgView.setImageBitmap(bm);
            }

            @Override
            public void onFailure(Throwable e) {

            }
        });
     }
