Ive been getting this error:

10-16 21:56:30.502: INFO/System.out(361): resolveUri failed on bad bitmap uri: android.graphics.drawable.BitmapDrawable@44f0c0c8

While trying to run this code

public class deals extends Activity{

        }
}

I've tried doing something similar to this lad:

"resolveUri failed on bad bitmap uri" when putting image on ListView

But I got a null pointer exception. Does anyone know how to get around this issue?

Answer 1

I am use given below code for fetching image for url try it i hope got your answer.

static Bitmap bmp;
private static File cacheDir;
static Bitmap bitmap = null;
static HttpURLConnection conn;

private static InputStream fetch(String urlString)
        throws MalformedURLException, IOException {

    conn = (HttpURLConnection) (new URL(urlString)).openConnection();
    conn.setDoInput(true);
    conn.connect();
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpGet request = new HttpGet(urlString);
    HttpResponse response = httpClient.execute(request);
    return conn.getInputStream();
}

Resources res;

// ***********New Function For Fatching
public static Drawable LoadImage(String URL) {
    Drawable drawable = null;
    Bitmap bm = null;
    try {
        if (fetch(URL) != null) {
            try {
                BitmapFactory.Options options = null;
                // options.inSampleSize=4;
                InputStream obj = (InputStream) fetch(URL);
                bm = BitmapFactory.decodeStream(obj, null, null);
                obj.close();
                conn.disconnect();
            } catch (OutOfMemoryError e) {
            } catch (IndexOutOfBoundsException e) {
            }
            drawable = new BitmapDrawable(bm);
            return drawable;
        } else {

            return null;
        }

    } catch (Exception e) {
        Log.e("GUIMethodClasas", "fetchDrawable failed", e);
        return null;

    }

}

Answer 2

Try this code:

URL url = new URL(yourImageURL);
HttpUrlConnection conn = (HttpUrlConnection)url.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
Bitmap b = BitmapFactory.decodeStream(is);
yourImageViewObject.setImageBitmap(b);

Hope this will help you! Happy Coding
