Android skimageDecoder :: Factory返回null

Question

當我從瀏覽器打開php文件時：“ http://192.168.1.30/save/load_image_from_db.php?id= ” + id; 圖像顯示正確，但是當我嘗試從android應用程序顯示圖像時，它不起作用，並且出現此錯誤：skimageDecoder :: Factory返回null。

即使我將其分配給從url.opencnnection（）。getStream（）獲得的流的解碼流，Bitmap對象仍然為null！

代碼：

 @Override
            protected Bitmap doInBackground(String... params) {
                String id = params[0];
                String add = "http://192.168.1.30/save/load_image_from_db.php?id="+id;
                URL url;
                Bitmap image = null;
                try {
                    url = new URL(add);
                    InputStream is = url.openConnection().getInputStream();
                    image = BitmapFactory.decodeStream(is);
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                return image;
            }
        }

嘗試這個 ：

@Override
 protected Bitmap doInBackground(String... params) {
        String id = params[0];
        String add = "http://192.168.1.30/save/load_image_from_db.php?id="+id;          
        Bitmap image = null;

        HttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet(add);
        HttpResponse response;
        try {
            response = (HttpResponse)client.execute(request);           
            HttpEntity entity = response.getEntity();
            BufferedHttpEntity bufferedEntity = new BufferedHttpEntity(entity);
            InputStream inputStream = bufferedEntity.getContent();
            image = BitmapFactory.decodeStream(inputStream);
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return image;
}
