从 Url 获取图像无法解码流：fileNotFoundException

Question

我知道这个问题被问了很多次，但我尝试了很多解决方案，但没有一个有效。

在 Android 上，我试图从 URL 获取图像以将其放入图像视图中。 不幸的是，我收到以下错误：

E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: http:/lorempixel.com/1920/1920/business (No such file or directory)

当我尝试从模拟器的浏览器访问此 URL 时，它可以工作。

我已经尝试过以下解决方案： Load image from url

How to get image from url website in imageview in android

how to set image from url for imageView

我的实际代码如下：

public class DownloadImage extends AsyncTask<String, Void, Bitmap> {

    ImageView imgView;

    public DownloadImage(ImageView imgView){
        this.imgView = imgView;
    }

    @Override
    protected Bitmap doInBackground(String... urls) {
        return download_Image(urls[0]);
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        if (result != null)
            imgView.setImageBitmap(result);
    }


    private InputStream OpenHttpConnection(String urlString) throws IOException {
        InputStream in = null;
        int response = -1;

        URL url = new URL(urlString);
        URLConnection conn = url.openConnection();

        if (!(conn instanceof HttpURLConnection))
            throw new IOException("Not an HTTP connection");

        try {
            HttpURLConnection httpConn = (HttpURLConnection) conn;
            httpConn.setAllowUserInteraction(false);
            httpConn.setInstanceFollowRedirects(true);
            httpConn.setRequestMethod("GET");
            httpConn.connect();
            response = httpConn.getResponseCode();
            if (response == HttpURLConnection.HTTP_OK) {
                in = httpConn.getInputStream();
                Log.e("CON ", "HTTP connection OK");
            }
        } catch (Exception ex) {
            throw new IOException("Error connecting");
        }
        return in;
    }


    private Bitmap download_Image(String URL) {
        Bitmap bitmap = null;
        InputStream in = null;
        try {
            in = OpenHttpConnection("http://lorempixel.com/1920/1920/business");
            bitmap = BitmapFactory.decodeStream(in);
            in.close();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        return bitmap;

    }
}

在主要活动中，我的代码是：

 ImageView img = (ImageView) findViewById(R.id.imageView);
 DownloadImage download = new DownloadImage(img);
 download.execute(url);

在我添加的清单中：

<uses-permission android:name="android.permission.INTERNET" />

我能做什么？

这很完美：

String urlPath = "http://anyWebsite.com/images/12"
Bitmap bm = BitmapFactory.decodeStream((InputStream) new URL(urlPath).getContent());
myImageView.setImageBitmap(bm);
